HEAT PUMP WATER HEATER COMPRESSOR CRITERIA
PAGE：5/30
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
Oil should be returned continuously to the compressor and not kept in the refrigeration system.
Oil level of compressor should be higher than 7.5 mm from the lubricating piece fixed on
the end of the crankshaft.
Compressor must not be started operated under a dual-layer separate status.
However, in case of foaming situation, the height of this foam does not mean the height of the oil level.
If you do not keep the oil level, the oil shortage will occur, and influence the reliability of compressor.
(Please check the oil level in the compressor with the sight glass we supply.)

There should be superheated gas returned to the compressor under all normal operating conditions.

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.

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 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.
