COMPRESSOR CRITERIA

1 Strictly observe the specification

The compressor should be used in specifications written in this “compressor specification” and

not be used in specifications outside it.. The main circuit must link up with fuse or breaker.

2 Source voltage

Specified inverter is linked up with compressor terminals . Applied voltage of this inverter should

be voltage specified in this “compressor specification”. Alternating voltage should never be applied

on terminals (for example：commercial alternating voltage of 1φ100V,200V,3φ200V).This is because

that if applied alternating current the direct current motor will demagnetize.

3 Operating voltage range

The compressor should be operated in the range of rated voltage ±10% , under standard condition

and overload condition of rated frequency (applied voltage to inverter).It must be satisfied

with item 5 ,6,7.

4 Operating temperatures and pressures

The operating temperatures and pressures of a compressor should be within the range shown in

the table 2 and graph 1.

5Oil Back and height of the oil level

The oil should be returned continuously to the compressor and the structure of the refrigerating

system should not make oil stay in the system. The oil level in compressor should be satisfied

with chart 2.If not keep the oil level, the shortage will occur, and influence the reliability of

the compressor.(please check the oil level in the compressor with the sight glass which supplied

form SHEC.

H EA T PU MP WA TE R HEA TE R CO MPR ES SO R CRI TE

RI A PAGE：6/30

The compressor should be continuously oiled back, and there should be no oil storage part in the refrigeration system

configuration. Also, the oil level in the compressor should meet the conditions in Figure 2. However, when a foam state

occurs and the liquid becomes foamy, this portion does not belong to the oil level. If the oil level is not met, the oil supply

to the sliding part will be insufficient, which will seriously affect the reliability. (It can be confirmed by a compressor with

a sight glass for observing the oil level).

Thereshouldbe superheated gas returned to thecompressorunderall normal operatingconditions.

6 Current limitation

Current peak among motor terminals（include instantaneous current peak）should be

below demagnetizing current in order to prevent magnet in motor from demagnetization.

7 Pressure difference between suction and discharge

In all allowable rotational speed range, the difference of pressure should be more than

0.39MPa{4kgf/cm2}. But if there is no problem of noise when assembled in air conditioner,

it can also below this value.

PAGE：8/30

8 Discharge pipe temperature

Discharge pipe temperature is measured at a distance 300mm from the surface of compressor

and should be less than 110℃. The tip of the thermocouple is fixed by soldering when

measuring discharge pipe temperature .Furthermore, soldering point is covered with urethane

foam to prevent the effect of wind.

9 Dust of compressor hermetic terminals

Compressor hermetic terminals should be mounted with specified cover in right way to prevent

dust entering, and should be used in direction which dust is hard to enter in.

10 Lead wire of compressor hermetic terminals

Measuring the temperature of hermetic terminals , lead wire should be resist to the temperature

and be clamped so as not in touch with the surface of compressor and pipe.

11 Start-stop frequency

The frequency should be less than 6 times per hour. Operating time from start to stop should

be more than 3 minutes. Stopping time should be more than 3minutes.

12 Rate of rotational speed change

The rate of compressor rotational speed (acceleration) should be less than 133min-1/s, But if

The variable range is below 120min-1, rate can also be less than 600min-1/s when rotational

speed is reduced to avoid temporary over-current.

13 Air and moisture in refrigerating system

The degree of vacuum in refrigerating system should be less than 20Pa (150×10－3mmHg) at

room temperature just before charging refrigerant. The quantity of water should be less

than 0.15ml.
