Semi-hermetic Reciprocating Compressors This service guide provides answers to some of the most common questions and issues in the field. For more information on design, selection, application data and the BITZER software please refer to the BITZER website at www.bitzerus.com. Please consider the following safety instructions prior to attempting to repair, test, start up or diagnose any issues with BITZER compressors. Authorized Staff All work on compressors and refrigeration systems should only be performed by refrigeration personnel who have been trained and certified to perform the task at hand. General safety references:

Warning! The compressor is under pressure with a holding charge of 7.25 to 29 psi above atmospheric pressure. Incorrect handling may cause injury to skin and eyes. Wear safety goggles while working on compressor. Do not open connections before pres-sure has been released. Caution! During operation, surface temperatures exceeding 140°F or below 32°F can be reached. Serious burnings possible. Lock and mark accessible sectors. Before working on the compressor: Switch off and let cool down. Warning! If working on the compressor after the plant has been commis-sioned: Compressor is under pressure! In case of improper handling serious injuries are possible. Release the pressure in the compressor! Wear safety goggles!

1.3 Serial Number Significance starting 01/09/2003

The serial number contains 10 figures. The first 2 digits indicate the factory, the 3 following digits indicate the manufacturing date, and the last 5 digits are running subsequently. Factory codes are the first 2 digits of the serial number (see Table 1). Date Codes are the next 3 digits that indicate the manufactur-ing date (use Table 3 for the 1st digit and Table 2 for the 2nd and 3rd digit).

Contact customer service at 770-503-9226 or email [email protected] for a RMA form. Please Note: A credit card number (or a PO if you have a BITZER account) is re-quired for the replacement compressor and core deposit. We will call you back with a delivery confirmation ASAP. Once a Return Material Authorization (RMA) form is filled out, we will also arrange to have your failed compressor picked up. BITZER will pay the freight back to the factory and, as soon as it arrives at the Atlanta area plant, we will issue you a credit against your core depos-it. BITZER does not charge a core charge for your replacement com-pressor if you adhere to the following procedures: 1. After receiving your replacement compressor, you have 2 weeks

to contact us to schedule the pick up of your core. If you fail to do so BITZER will execute the core charge on your current PO.

2. The compressor should be shipped fully sealed: Use blank offs

or the service valves shipped with replacement compressor. 3. Attach Return Material Authorization form to the compressor.

Your RMA form will be issued when placing your order.

Explanation of Application Limits Diagram of Semi Hermetic Reciprocating Compressors

Figure 2.9.1.Simplified application limits diagram Limitations of the application limits diagram:

1-Pressure differential / pressure ratio If the pressure differential / pressure ratio of the compressor gets too low the resulting force is insufficient to properly open or close the reeds on the valve plate. This can lead to a breakage of the reeds. Furthermore the volumetric displacement decreases due to reverse expansion from the pressure chamber into the working chamber.

2.6 Application Limits

2 Compressor Data

www.bitzerus.com 35

2-Maximum evaporating temperature If the compressor operates at an evaporating temperature close to the maximum allowed evaporating temperature the compressor deliv-ers a high refrigerant mass flow. Hence high forces develop on bear-ings and drive gear. 3-Motor Load The motor load of a semi hermetic reciprocating compressor de-pends on the operating point. The higher the evaporating tempera-ture and the higher the condensing temperature, the higher the corre-sponding motor load. 4-Maximum condensing temperature The maximum condensing temperature is limited by the saturated vapor pressure as well as the maximum allowable operating pressure on the high pressure side of the compressor. According to EN378-2 the maximum allowable operating pressure of the systems with pres-sure relief devices must not exceed 0.9 x maximum allowable operat-ing pressure. 5-Minimum evaporating temperature With decreasing evaporating temperature the saturated vapor pres-sure of the refrigerant decreases as well. For safe operation the cir-cuit should not be operated at pressures too much below ambient air in order to avoid penetration of ambient air into the suction side of the system through a leakage. At low evaporating temperatures the refrigerant mass flow of the compressor as well as the suction gas density are decreasing. This can possibly lead to an insufficient motor cooling as the delivered refrigerant mass flow is too low. 6-Thermal limit At low evaporating temperatures in combination with high condensing temperatures the thermal load limit of the compressor restricts the operation. There are various possibilities to extend the application limits such as water cooled cylinder heads, additional fans, restricting the allowable suction gas superheat or, in individual cases, a direct liquid injection into the suction side of the compressor. The recom-mended methods for additional cooling are displayed in the applica-tion limits diagram as icons.

BITZER semi-hermetic reciprocating compressors are characterized by their universal applications. Our standard reciprocating compres-sors can be applied with R22, R404A, R507A, R134A, R407A and R407C in high, medium or low temperature applications. The compressors are equipped with highly efficient large volume electric motors. According to UL specifications, contactors and cables can be selected by either MCC and RLA or by means of the MOA (maximum operating amps) specified in the following tables. When using MCC to select contactors and cables, the value of RLA = MCC/1.40 should be used for sizing contactors. All other elec-trical sizing should be based on RLA = MCC/1.56. When using MOA to select contactors and cable, use UL listed circuit breakers set to trip at no more than 125% of the MOA. The circuit breaker should not be sized less than 110% of the MOA value to avoid nuisance tripping. Note: All electrical calculations are based on 3 phase at 60Hz.

SE-B3 When installing a dual voltage INT, the service tech should conduct the following tests to ensure proper operation:

WITH THE POWER OFF, remove one of the leads from

either M1 or M2 on the compressor terminal board.

Turn on the power and confirm that the control voltage ap-

pears between terminal 12 and N on the device.

If an optional signal light (H1) is used, it should be illuminat-

ed.

NO voltage should appear between terminal 14 and N.

Please Note: After supplying power between L and N, there will be a 3-second time delay. Manual Reset A manual reset function prevents the compressor from restarting and eliminates short cycling. This can be reset by briefly interrupting the supply voltage for 5 seconds, either by means of the main switch or by a reset push-button which can be installed in the supply line. Automatic Reset In exceptional cases, the lockout function can be cancelled by remov-

ing the link between B1-B2. The compressor then restarts automati-

cally after cooling down. This modification is only permissible if the

cycling rate is limited to 6-8 starts per hour by using an additional

time-lag relay or timer.

Note: INT trips at 4500Ω

The typical resistance at ambient conditions for M1 and M2 is

150Ω - 650Ω.

Oil Monitoring Devices: Delta-P II: Monitors oil pressure differential of compressors with oil pumps OLC-K1: Optically monitors oil presence at the crankshaft of centrifugal disk (Octagon “S”) compressors

Technical Features:

The Delta-P II and OLC-K1 consists of two parts: a sensor unit

and an electronic unit.

Because the mechanical component screws separately into the

BITZER housing, the hermetically sealed electrical piece can be

replaced without refrigerant or oil loss.

Device Trip:

Delta-P II:

If the differential oil pressure drops below 9.5 ± 2 psid (for any

amount of time) a red light will illuminate on the front of the elec-

trical unit.

If the pressure remains below for 9.5 ± 2 psid for longer than the

allowable time (see chart below) then the output relay opens

(stopping the compressor).

OLC-K1:

If there is no oil present for any amount of time in the oil pocket

(center of front bearing cap), a red light will illuminate on the

front of the electrical unit.

If no oil is sensed for longer than the allowable time (see chart

below) then the output relay opens (stopping the compressor).

Delta-P II / OLC-K1:

In case the supply voltage is too low or if the electronic unit is

not properly mounted, the device will lock out after 5 seconds.

The LED at the front end of the electronic unit will flash.


62 www.bitzerus.com

LED indications:

LED is off: Sufficient oil supply

LED is on (red): Insufficient oil supply (presently)

LED is flashing (red): Fault (Voltage or installation)

Manual Reset

Interrupt power supply for at least 5 seconds.

Note: Always try to diagnose the issue in the event of an oil trip in-

stead of repeatedly resetting it. (Tip: View the red LED indicator to

see if oil is intermittently dropping out)

Wiring (see following page):

The Delta-P II and the OLC-K1 have identical wire connections:

Brown and Blue are the main power and used for resetting.

Gray and Orange are the relay (should be in series with the

control circuit). They will close when there is power to the unit

and the oil supply remain sufficient (see chart for trip delays)

Pink is the alarm part of the relay. Gray and Pink will close dur-

ing an oil trip or when there is no power to the unit.

Violet is a run proof to start timing sequences. This must have

power only when the compressor is on (typically uses the N.O.

auxiliary contacts of compressor contactor).

Troubleshooting Tip:

If there is a similar compressor adjacent, unscrew electrical units and

temporarily swop to see if issue stays with compressor or device.

4.4 Capacity Regulator

The BITZER capacity control is based on the principle of suction shut

-off. Hereby the suction-side gas flow to the individual cylinder bank

is shut off by means of a control piston.

In Full-load operation the compressor delivers on all cylinders. The

solenoid coil is DE-ENERGIZED. The gas ports in the valve plate and

cylinder head are opened.

In Part-load operation the pistons of the switched-off cylinder bank

run idle without gas pressure. The solenoid coil is ENERGIZED, the

suction port in the corresponding cylinder head is shut off by means

of a servo valve.

Application limits with part load operation With capacity regulator operation the temperature level rises due to:

reduced refrigerant mass flow,

reduced motor cooling and

electrical and mechanical losses.

Therefore the application ranges of the capacity controlled compres-

sors are restricted to some extent.

Attention! For low temp applications and open drive reciprocating

compressors the use of capacity control is restricted.


70 www.bitzerus.com

Capacity regulator head kit (w/gasket and stem) part numbers:

Possible Combinations for CR Heads:

* In case of base load sequence change, each compressor side must be equipped with the same number of regulators.

** One compressor side shut off. This operation mode should be preferred in view of operating reliability and compressor life.

6.1 Operating Temperatures and Oil Guidelines

Guide values for operating temperatures*

*Values in practice depend much on operating conditions (A/C, medi-

um temp., low temp.) and refrigerant! Please check individual cases

with the selection software or BITZER.

Note: Compressor/Oil Pump rotates in both directions.

Guide values for oil maintenance

**Oil heater recommended.

6 Preventive Maintenance / Service

76 www.bitzerus.com

Operating Temperatures

Suction gas superheat min. ~15°F

typical 20-30°F

Discharge gas temperature min.

40°F above condensing temp. (50° F for R22)

max. 250°F; measured at discharge line

2 Stage Intermediate (middle) pressure superheat

min. ~40°F+subcooler saturation temp;

measured at bulb on MP line

Oil Guidelines

Oil temperatures - on Start-up**

typical 25-35°F above ambient

Oil temperatures - Operating

min. 95°F (min. 55°F > SST)

max. 170°F

Oil pressure differential min. 9.5 ± 2 psi (see pg 61-62 for oil

monitoring devices)

Oil change Every 3 years or 10000 hrs of

operation

Note: When changing oil, remove the oil strainer to inspect and clean.

6.2 Switching Frequency and Vibrations

Vibrations on the high pressure side

Vibrations on the high pressure side of refrigeration systems are

mainly caused by: Pulsations, Structure-borne vibrations, Frame

design / basement

Pulsations

Pulsations (longitudinal gas vibrations on the high pressure side) are

created by the discharge process of the gas out of the cylinders.

Their amplitude and frequency depend on:

Compressor speed

Number of cylinders

Cylinder alignment

Refrigerant properties (pressure, temperature and sonic speed)

Critical discharge gas vibrations can be found if the frequency of the

oscillating gas column in a straight discharge tube section gets into

resonance with the natural frequency of the pipework. In the worst

case this could result in a fracture of the piping. The length of the

pipe segment with a resonance frequency corresponding to the natu-

ral frequency of the gas flow is designated as "critical pipe length".

6.5 Cylinder head and valve plate replacement guidelines


80 www.bitzerus.com

1. Remove cylinder head bolts. 2. If a capacity regulator (unloader) is installed, remove the bolts

holding the unloader stem as they are part of the cylinder head bolts.

3. Remove the cylinder head. 4. Remove the valve plate and inspect for damage. 5. Install a new valve plate gasket 6. Install a new valve plate. -Note: the new valve plate may look different than the original (number of discharge reeds and diameter of holes may vary) - this is normal and will not affect performance. -Use the dowel/guide pins to align and hold the gasket and valve plate correctly. 6. Install a new head gasket 7. Replace the cylinder head, tighten the screws crosswise and in

at least two steps. Torque the screws to the appropriate force listed on page 78.
