Case 4 is realized to 3 heating and thermal insulation of double-tube heat exchanger.
Correspondingly, in conjunction with above scheme, as shown in Figure 1, the present invention also provides a kind of water chiller-heater unit compressor heats to return
Control method is received, applied to water chiller-heater unit compressor heat recovery system described above；Include the first heat-exchanger rig, store
Boiler 2 and water pump 4；First heat-exchanger rig is sheathed on 1 shell of compressor, for absorbing the heat of compressor case；Nothing
When being in heating or cooling condition by water chiller-heater unit, when 1 skin temperature T1 of compressor is higher than preset temperature TS, water pump 4 starts,
It is stored so that the heat transferring medium in the first heat-exchanger rig enters in hot water storage tank 2 by first flow path 12, can be filled in this way
Divide the waste heat using compressor, avoid wasting, while can radiate to compressor, improves the compressor service life.
Preferably, in conjunction with above scheme, as shown in Figure 1, further including having condenser and the second heat exchange dress in the present embodiment
It sets；Second heat-exchanger rig is sheathed on condenser；When water chiller-heater unit is in heating condition, 1 skin temperature T1 high of compressor
When preset temperature TS, 1 skin temperature T1 of compressor are higher than condenser casing temperature；Water pump 4 starts, so that the first heat-exchanger rig
Interior water absorb after the heat of compressor case by first flow path 12 be directly entered in the second heat-exchanger rig with to condenser into
Row heat exchange；Further, when unit disorderly closedown or user force to shut down for a long time, condenser, which is in, to be needed to heat shape
State, and when the temperature of water is higher than condenser casing temperature in hot water storage tank 2, water pump starting, the water in heat storage tank is by first-class
Road 12 is directly entered to carry out heat exchange to condenser in the second heat-exchanger rig, to heat to condenser；Specifically, this is pre-
If temperature TS may be set to 45 DEG C to 50 DEG C, so that compressor has good heat radiating, to guarantee that internal part operates normally,
And lubricating oil has good lubricating action.
Using the above scheme, can the abundant heat that distributes of Collection utilization water chiller-heater unit compressor case, to compressor
Play the role of cooling down, while effectively reducing the consumption of system thermal energy efficiently using above-mentioned heat come heat hot water heat exchanger components
It dissipates and wastes.
Scheme provided by the invention can effectively recycle the heat generated when the operation of water chiller-heater unit compressor, avoid pressing
The heat dissipation of contracting machine shell is bad, and compressor part is caused to damage；Heat of compressor is made full use of to come to water system heat exchanger components simultaneously
Heating and thermal insulation is carried out, prevents water temperature too low, leads to water system heat exchanger components bursting by freezing, avoid the dissipation and waste of system thermal.
The above, only presently preferred embodiments of the present invention not do limitation in any form to the present invention.It is any ripe
