After become Working medium gas, after heat exchanger (18), gas-liquid separator (15) by compressor (1) suck.Cross colod-application evaporator and
In running order evaporator just replaces rotation in sequence to intervals Δ T, i.e. certain evaporator is in current Δ T
The interior supercooling for worker quality liquid, and it is then in running order in next three Δ T, so repeat down.Δ T according to
The atmospheric temperature and humidity adjust automatically detected, when temperature is in 5 DEG C~-5 DEG C ranges, and relative humidity is more than or equal to 75%,
Δ T is adjusted to 10min, and when relative humidity is less than 75%, Δ T is adjusted to 15min；In the case of remaining, Δ T is adjusted to 20min.This
The special defrosting system that removes need not be arranged in kind heat pump system, and system constitutes fairly simple.Oil level control is configured per compressor
Device, when oil level is higher than upper limit value, oil feed line is cut off, fuel cut-off；When oil level is less than lower limiting value, oil feed line is beaten
It opens, to compressor oil-supplying.In this way, according to the oil mass demand of every compressor, oil container (17) can by oil feed line (5) and
When to every compressor repairing.
The heat transfer effect and drag losses for considering heat exchanger (18) generation, when temperature is higher than 10 DEG C or less than -10 DEG C
When, two by-passing valves of the import and export of heat exchanger (18) are opened, and heat exchanger (18) is made to be stopped.
Embodiment two
