Doc. Code MP01E+

DESCRIPTION

Static cooling: the compressor does not require forced cooling, but it must be installed so that the ambient air can adequately cool to avoid overheating. Fan cooling: the compressor requires forced cooling through the use of a fan, sized as indicated in section 6.10 “Compressor Cooling”. With oil cooler: coil positioned in the lower internal part of the housing, immersed in the lubrication oil, where the gas coming from the first part of the heat exchanger circuit circulates.

COMPRESSOR PRESSURISATION The compressor is pressurized to a pressure of about 0.2 bar with dry air (dew point lower than -40 °C); the tubes are sealed with rubber plugs to maintain this pressure. The compressors for use with hydrocarbons are supplied without pressurization.

3.7

OIL CHARGE Table 11 shows the lubricant charged in the various series of compressors. The quantity is indicated in the General Catalog and Technical Bulletin. Only in an exceptional case, in accordance with the Sales Department, can the compressors be shipped without oil. In the interest of warranty, occasionally additives or substitution of the lubricant, can be made by the customer under the approval of Embraco Europe. A colored “O” stamped on the compressor cover indicates the presence and type of oil (for color and oil type see Table 11). The maximum humidity content in the oil is 40 ppm.

(1) The different load structure (1.800 or 1.944 NE series compressors - 1.260 or 1.512 T compressors) is determined by the ratio between the maximum container weight and the compressor weight. (2) No. 3 package filler is added (containing all the equipped components). (3) A package as filler packaging, containing part of the equipped components is added. (4) Type of load which is rarely used. To be avoided due to an incomplete 3rd layer. Packages are added containing the equipped components.

Shipments by truck

5.2.2

The transportation of compressors by truck is the most common system for highway or short distances where the stresses on the product are reduced. This type of transportation, if made without the necessary precautions on load steadiness and travel on uneven roads can cause stresses to compressors with possible damages to the suspension springs and to the internal discharge mufflers. For an Embraco 24,000 kgs (11,000 lb) truck, the load composition is as follows in Table 17: Table 17

ACCEPTABLE COMPRESSOR POSITIONS DURING TRANSPORTATION

5.3

For the finished product (compressor assembled in the application), certain transportation conditions do not require that the compressor is positioned upright. Table 18 represents the various acceptable transportation positions. Any position not listed below is prohibited. Table 18

NB NE

For the solution of potential positioning problems during assembling and transport, please consult the Technical Assistance - Sales Department. MAXIMUM ALLOWABLE RATE OF DECELERATION DURING THE TRANSPORT: 1g

We advise against the transport by rail, even if correctly performed, because during the shunting, stress to the compressors from decelerations can cause stator shifts, or deformation or breaking of brackets and internal discharge tubes.

Guide for the use of R290

6.4.5.1

General information The refrigerant R290 (propane) is used to substitute R22, as well as R404A, for low and medium back pressure applications, and air conditioning. Before supplying compressors for use with R290, it is first necessary to perform an evaluation of the risks involved with the use of this refrigerant. The customer should perform a risk assessment to ensure proper knowledge about the handling and use of the R290 in the refrigerant system (for further information please contact the Technical Assistant Department at Embraco Europe). Refrigerant R290 can normally be used in the same compressor designed for use with R22, but with a different (hermetic type) thermal overload protector. Tabella 29

(Ref.: R 22 = 0.05) (Ref.: R 22 = 1700)

PLEASE NOTE: R290 is flammable and should then be handled by qualified personnel in accordance with the rules and regulations now established for safe use.

6.4.5.2

System component compatibility All of the components in the refrigeration system that may contain contaminants should conform to the requirements outlined in norm DIN 8964(1). The presence of the contaminants paraffin and silicon is not permitted.

6.4.5.3

Expansion device For a new application the first component to be dimensioned should be the capillary tube. To prepare the prototype, use chapter 6.6 - CAPILLARY TUBES as a reference. Generally, when changing a system from R22 to R290, the same capillary tube can be used although the length should be decreased by approximately 5%. It is not recommended to use a capillary tube with an internal diameter less than 0.6 mm. For each system the optimal dimensioning of the capillary tube should be performed in an appropriate test laboratory, in order to obtain the best working conditions.

6.4.5.4

Evaporator and condenser Generally to convert a system from R22 to R290, the same evaporator and condenser may be used. (1) The soluble residual contents and solid residues must be less than 100mg /m2 of system internal surface area. Of this, a maximum of 40 mg/m2 can be soluble and the maximum of 60mg /m2 can be insoluble (for the definitions of solid/soluble and additional details refer to the norm mentioned above).

INFORMATION ABOUT CORRECT COMPRESSOR INSTALLATION 6.4.5.5

Filter dryer Refrigerant R290 requires the use of a normal filter drier type XH-9 (See Chapter 6.5 - Filter Dryer) Always consult the manufacturer for the proper selection of the filter drier.

6.4.5.6

Evacuation and charging equipment Generally the vacuum level for an R290 system is the same used for a system with R22. Good refrigeration practice suggests system evacuation from both low side and high side, achieving a minimum level of 0.14 mbar (100 ÂľHg) with a non-condensable value of less than 0.3% by volume. Use charging equipment suitable for use of the refrigerant R290, and if possible, dedicate this equipment for use only with this refrigerant.

6.4.5.7

Refrigerant charge Generally the quantity of the refrigerant R600a introduced into the system can be reduced from 50% Ăˇ 60% compared to the required charge of R22. This characteristic greatly reduces the legal risk of flammability of the refrigerant in case of a system leak. For each system the optimal refrigerant charge should be determined in an appropriate test laboratory in order to obtain the best working conditions.

6.4.5.8

Moisture In order to avoid problems that can shorten life of the refrigeration system, use components that are supplied internally dried and properly sealed to prevent the entrance of moisture. These components should remain sealed until they are used. The moisture content in a system should conform to norm DIN 8964(1). The level of moisture present in the refrigeration circuit should be below 40ppm and after the system has been operating, the filter dryer should remove moisture from the system from a level below 20ppm.

6.4.5.9

Leak control It is recommended that special attention be given to the correct welding, or other forms of union of the system components, to avoid the possibility of leaks. To guarantee the maximum efficiency in controlling leaks, it is recommended to use a leak detector designed for use with refrigerant R290, or as an alternative, a detector designed for use with Helium.

6.4.5.10

High pressure limit control To protect the system, it may be necessary to install a high pressure limit switch to control the maximum discharge pressure. The settings on this limit switch should be in accordance with the limits established in Chapter 7.1.3 - Discharge gas maximum pressures.

(1) The soluble residual contents and solid residues must be less than 100mg/m2 of system internal surface area. Of this a maximum of 40 mg/m2 can be soluble and the maximum of 60mg /m2 can be insoluble (for the definitions of solid/ soluble and additional details refer to the norm mentioned above).

The filter drier must be chosen with the molecular sieve suitable to the refrigerant type used in the system as indicated in the Table 31. Table 31

MOLECULAR SIEVE

4A-XH-5 (8 = 12) 4A-XH-6 (8 = 12) XH-7 (8 x 12) XH-9 (8 = 12)

For the applications with R134a - R404A, we suggest to increase the weight of the molecular sieve by 10% ÷ 15% compared to the corresponding applications with R12 - R502. The filter drier must be properly protected from absorption of ambient humidity during assembly of the system according to the following practices:

Remove the protection caps from the filter shortly before welding.

The filters supplied without protection caps, in “blister” or in “hermetic boxes” must be duly protected to avoid moisture absorption before welding.

A reduced absorption capacity can cause an incomplete water absorption by the molecular sieve, therefore, the moisture could circulate freely in the system with the following effects indicated in Table 32. Table 32

Inconvenient caused by moisture in the system 1 Ice build-up:

2 Acid build-up:

3 Oil contamination:

Doc. Code MP01E+

Emission 2000-04

Reduces the cross-sectional area of the capillary tube, or expansion valve, up to their complete obstruction. Causes serious problems in the compressor and to the molecular sieve of the filter. Typical marks and consequences are: Copper plating of valve plate, valve reeds, crankshaft bearings, etc. Etching of electric motor insulation by acids, with burning of motor windings. Destruction of the filter with disintegration of molecular sieve and build-up of “dusts”. Wears and blocks alternative and rotating mechanical parts. Causes acidification and reduction of its lubricating power, with change of oil color (brown). It can cause build-up of sludge, with subsequent poor lubrication of compressor.

CAPILLARY TUBES

6.6

During the initial steps of the design of a new cabinet Table 33 can provide a helpful guidance for selecting the most appropriate capillary tube dimensions to start with. The exact size of the capillary must however be found according to the results of the laboratory tests performed on the prototype cabinets. The values, indicated on Table 33, have been determined according to the following considerations: LBP-MBP-HBP Applications: with heat exchanger of minimum length 0.9 m and with 0 °C sub-cooling. Air Conditioning Applications: with condensing temperature of 54 °C, sub-cooling of 8 °C, return gas temperature 18 °C. Table 33

VACUUM OPERATIONS

6.11

It is fundamental to perform a proper evacuation of the refrigeration system to ensure proper running of the refrigerating machine, and to preserve the life of the compressor. A proper evacuation process assures that the air and moisture contents are below the allowed limits. The introduction of new refrigerants require the use of new polyester oils with characteristics of high hygroscopicity which require the greatest care in system evacuation. There are various methods to evacuate a refrigeration system: one-side (low pressure side), two-side (low and high pressure sides), at different times, with phases of refrigerant pre-charge, etc. We must aim to reach a vacuum value (measured at its stabilization on both the low and high pressure sides), better than 0.14 mbar (100 µHg), and the maximum level of non-condensable must not exceed 0.3%. PLEASE NOTE: To avoid irreparable damages to the compressor, never start it under vacuum (without refrigerant charge).

REFRIGERANT CHARGE

6.12

After the vacuum operation, the system must be charged with the refrigerant type indicated on the compressor nameplate or one of the alternate allowed types, in the pre-determined quantity. For a correct charge we suggest, after carrying out the vacuum, to pump part of the refrigerant into the compressor to “break” the vacuum; then start the compressor to draw the remaining part of the charge. In the small refrigerating systems utilizing few grams of charge, the refrigerant is usually pumped into the compressor through the service tube. In this case you must wait 5 to 10 minutes (time depending on the refrigerant quantity and on the ambient temperature), before starting the compressor. This to allow partial refrigerant evaporation and to avoid the suction of liquid refrigerant into the compressor cylinder. PLEASE NOTE: The refrigerant mixtures must be charged in the system exclusively at liquid state. Table 37

Maximum Refrigerant Charge SERIES REFRGERANT CHARGE (g)

EM - NE

NJ - NT

350

500

800

In case the refrigerant charge should exceed the max values allowed for the compressor, take care that the circuit is equipped with liquid receiver, and, for larger systems, an oil heater in the compressor housing to avoid mixing of refrigerant in the oil, foaming with subsequent liquid suction and pumping. If it becomes necessary for a technician to recharge the system in the field, he should first remove all of the remaining original charge, and then recharge the system in accordance with the refrigerant quantity indicated on the data plate. PLEASE NOTE: The use of the compressor outside the intended working range cannot make use of the warranty.

Compressor operating fields

Within the minimum and maximum values typical for each model.

In the diagrams represented on the following pages, indicated are the limits of evaporating, condensing, ambient and return gas temperatures. The compressor can operate within the limits of evaporating and condensing temperatures defined by the outlined area bordered by a continuous line, at the indicated conditions of ambient and return gas temperature. Outside these operating fields, the system operates at high pressures and high temperatures, and cause early defects in the compressor. The compressor defects caused by applications operating outside the prescribed fields will not be considered under warranty. 7.1.5.1

R22 Compressors operating field The production of R22 compressors was required for the replacement of R12 - R502 refrigerants and the choice has been obliged by the non availability at that moment of other suitable alternative gases. For low and medium temperature R22 cabinets, compressors must be selected according to the limits associated with this type of gas, that was developed for high evaporating temperatures, thus characterized by restrictive limits.

RUNNING DATA AND COMPRESSOR CHECKING PROCEDURES 7.4.2

Standard version RSIR - RSCR EM Series with PTC starting device (Refer to the RSIR e RSCR electric diagrams represented on Figure 10, page 24) Verify with a voltmeter the presence of the correct voltage on the “L” and “N” terminals of the PTC starting device. If there is insufficient voltage, the thermostat is defective due to open contacts, connections, or an interruption in the cables. Disconnect the other electrical components if present (motor fan, gear motor, etc.), disconnect the voltage to the circuit at the supply line, and carry out the following operations and checks: 1. Check the continuity on the terminals L3 of PTC starting device. If continuity lack,s the thermostat must be replaced due to open contacts. 2. Take off the PTC starting device from the hermetic terminal. 3. If there is a run capacitor (RSCR version) disconnect it. 4. Take off the protector from the PTC starting device and check between points 1 and 3. If there is no continuity, be sure that the protector has no open contacts due to its trip. In this case, repeat the check after about 10 minutes. Otherwise, the protector is defective due to open contacts. 5. Check the electric motor according to the procedure described in par.7.5.1. 6. Check the ohmic resistance of the stator run and start windings according to the procedure described in par.7.5.2. 7. On the PTC starting device check between the two fastons N and 2, the ohmic resistance of the PTC pill which must be 8÷16 for the 230V model and 2÷4 for the 115V model, at the ambient temperature of 25 °C. (CAUTION: the ohmic resistance values measured with a normal tester can be out of the indicated by as much as 25% ÷ 30%). 8. If there is a run capacitor (RSCR version), check it according to the procedure described in section 7.5.3. If from all the above checks no problem was found, there is no capillary clogging and the system does not yet run correctly, replace the compressor.

7.4.3

Standard version RSIR NB - NE - NT - T Series with electromagnetic current relay (Refer to the RSIR electric diagram represented in Figure 11, page 25) PLEASE NOTE: The contacts of the starting relay are normally open. Verify with a voltmeter the presence of the correct voltage on terminals “1” of relay and “3” of protector. If there is insufficient voltage, the thermostat is defective due to open contacts, connections, or there is an interruption in the cables. Disconnect the other electric components if present (motor fan, gear motor, etc.), disconnect the voltage to the circuit at the supply line, and carry out the following operations and checks: 1. Check the continuity between the points “1” - “3” of protector: If there is no continuity, be sure that the protector has no open contacts due to its trip. In this case, repeat the check after about 10 minutes. 2. Take off the start relay from the hermetic terminal and keeping it in the same vertical position, (do not incline or overturn) carry out the following continuity checks. 3. Between the terminals “1” and “S” on the relay: If there no continuity the relay is faulty due to closed contacts.

RUNNING DATA AND COMPRESSOR CHECKING PROCEDURES 4. Between the terminals “1” and “R” of relay: If there is no continuity the relay has an open coil. 5. Check the electric motor according to the procedure described in par. 7.5.1. 6. Check the ohmic resistance of the stator run and start windings according to the procedure described in par. 7.5.2. If from all above checks, no problem was found, there is no capillary clogging, and the system does not yet run correctly, replace the starting relay, excluding possible faults of contacts opening and closing (pick-up and drop-out current) that can not to be determined with above checks. If the compressor does not yet run correctly, it must be replaced due to internal defects. 7.4.4

Standard version CSIR NB - NE - NT Series with electromagnetic current relay (Refer to the electric diagram CSIR represented in Figure 11, page 25) PLEASE NOTE: The contacts of starting relay are normally open. Verify with a voltmeter the presence of the correct voltage on the terminals 2 of relay and 3 of protector. If there is insufficient voltage, the thermostat is defective due to open contacts, connections, or there is an interruption in the cables. Disconnect the other electric components if present (motor fan, gear motor, etc.), disconnect the voltage to the circuit at the supply line and carry out the following operations and checks: 1. Check the continuity between the points 1 and 3 of the protector. If continuity lacks, be sure that the protector has no open contacts due to its trip. In this case repeat the check after about 10 minutes. 2. Take off the start relay from the hermetic terminal and keep it in the same vertical position (do not incline or overturn). Carry out the following continuity checks: 3. Between the terminals 1 and S on the relay: if there is continuity the relay is faulty due to closed contacts. 4. Between the terminals 2 and R of relay: if there is no continuity the relay coil is open. 5. Check the electric motor according to the procedure described in section 7.5.1. 6. Check the ohmic resistance of the stator run and start windings according to the procedure described on section 7.5.2. 7. Check the start capacitor according to the procedure indicated on section 7.5.3. If from all the above checks, a problem was not found, there is no clogging in the expansion device and the system does not yet run correctly, replace the starting relay, excluding possible faults of the contacts opening and closing (pick-up and drop-out currents) that can not be determined with above checks. If the compressor does not yet run correctly, it must be replaced due to internal defects.

If there is insufficient voltage, the thermostat is faulty due to open contacts, connections, or there is an interruption in the cables. Disconnect the other electric components if present (motor fan, gear motor, etc.), interrupt the voltage to the circuit disconnecting it from the supply line and carry out the following operations and checks: 1. Disconnect all the connections on terminals 2 and 5 of the starting relay. 2. Check the continuity between terminals 2 and 5 of the starting relay. If there is no continuity, there is a broken coil and the relay must be replaced. 3. Check the continuity between the terminals 1 and 2 of the starting relay. If there is no continuity, the contact is open and the relay must be replaced. 4. If there is an external overload protector, check, according to the type, the continuity between the terminals 1 and 3 or 1 and 2. If there is no continuity, the protector can be faulty or there could have been a trip, so repeat the check after about 10 minutes.

Check the start and run capacitors according to the procedure described in section 7.5.3. 9. Check the continuity of the cables disconnected from the 2 and 5 terminals of the starting relay. If from all above checks, no problem was found, there is no clogging in the expansion device, and the system does not yet run correctly, replace the starting relay, excluding possible mistakes of opening and closing of the contacts (pick-up and drop-out currents) that can not be found with above checks. If the compressor does not yet run correctly, it must be replaced due to internal defects. 7.4.10

Standard versions CSIR and CSIR BOX NT and NJ Series with current electromagnetic relay (Refer to electric diagrams CSIR represented on Figure 17, page 28) (Refer to electric diagrams CSIR BOX represented on Figure 18, page 28) PLEASE NOTE: The contacts of the starting relay are normally open. Verify with a voltmeter the presence of the correct net voltage on the terminals 3 and 5 of the starting relay. If there is insufficient voltage, the thermostat is defective due to open contacts, connections, or there is a break in the cables. Disconnect the other electric components, if present (motor fan, gear-motor, etc.), interrupt the voltage to the circuit at the supply line, and carry out the following operations and checks: 1. Disconnect all connections on terminal 3 of the starting relay. 2. Keeping the start relay in the same vertical position as assembled on the hermetic terminal (do not incline or overturn), carry out the following continuity checks: 3. Check the continuity between the terminals 3 and 4 of the starting relay. If there is no continuity, the coil is interrupted and the relay must be replaced. 4. Check the continuity between the terminals 1 and 2 of the starting relay. If there is continuity, the contact is closed and the relay must be replaced. 5. Check the protector continuity between points 1 and 3. If there is no continuity, the protector can be: Â&#x2021;

defective

Â&#x2021;

tripped; then repeat the check after about 10 minutes.

6. Check the electric motor according to the procedure described in section. 7.5.1. 7. Check the ohmic resistance of the stator start and run windings according to the procedure described in section 7.5.2. 8. Check the start capacitor according to the procedure indicated in section 7.5.3. 9. Check the continuity of the cables disconnected from terminal 3 of the start relay. If from all above checks, no problem was found, there is no clogging in the expansion device, and the system does not yet run correctly, replace the starting relay, excluding possible mistakes of opening and closing of the contacts (pick-up and drop-out currents) that can not be found with
