HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM 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 usedin specifications outside it. Moreover, accessories should be specified parts used in
specified way, service must use specified parts too. The main circuit must link up with fuse or
breaker.
2 Source voltage
Specified inverter is linked upwithcompressor 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 1 100V,200V,3200V).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 rangeof 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 1.

5Current limitation
Current peak among motor terminals（include instantaneous current peak）should be
below 29.0A(at130 ) in order to prevent magnet in motor from demagnetization.℃
6 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.
7 Discharge pipe temperature
Discharge pipetemperature is measured at a distance300mm from the surface of compressor
and should be less than 110℃. The tip ofthe thermocouple is fixed bysoldering when
measuring discharge pipe temperature .Furthermore, soldering point is covered with urethane
foam to prevent the effect ofwind.
8Air leakage test pressure
The pressure should be less than 2.847MPa{28kgf/cm2G}.
HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM PAGE:8/30
9Oil back and 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 higher than 7.5 mm from the lu
b
ricating piece fixed
on the end of the crankshaft.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.
10 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.
11 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.
12 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. But oil level should be met
to item 8. Suction and discharge pressure should balance completely before restarting.

13 Rate ofrotational 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. The change of compressor rotational speed is referred to chart 3.
14 Air and moisture in refrigerating system
The degree of vacuum in refrigerating system should be less than 133Pa (998×10－3mmHg) at
room temperature just before charging refrigerant. The quantity of water should be less than 0.15ml.
