Fig. 2 is the refrigeration principle block diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As shown in Figure 1, secondary is under-voltage formula multi-functional fluid seedbed source heat pump device comprises heat-exchange system and compressor, and said compressor is single Spiral Lobe Refrigeration Compressor; Be provided with the refrigerating/heating handover control system between said heat-exchange system and the said compressor.
Said heat-exchange system comprises condenser group and evaporimeter, and said evaporimeter is the shell-tube type dry evaporator; Be provided with liquid storage cylinder between said condenser group and the said evaporimeter, be provided with expansion valve between said liquid storage cylinder and the said evaporimeter; Said condenser group comprises first-stage condenser and secondary condenser, and said first-stage condenser and said secondary condenser are shell and tube condenser; Said first-stage condenser is connected with said refrigerating/heating handover control system, said liquid storage cylinder and said secondary condenser respectively, and said secondary condenser is connected with liquid storage cylinder with said first-stage condenser respectively.Be provided with main temperature controller between said evaporimeter and the said refrigerating/heating handover control system; Be provided with auxilliary temperature controller between said first-stage condenser and the said secondary condenser.
As shown in Figure 2, introduce the refrigeration work principle of this heat pump assembly below:
When the cold-producing medium of saturation state from pipeline, be inhaled into compressor and compress, through after the compressor compresses; Refrigerant vapour reaches the state of superthermal HTHP, gets into first-stage condenser through pipeline, and cold-producing medium is condensed into liquid through after the first-stage condenser; Have most of the entering in the secondary condenser to proceed condensation then, sub-fraction directly and after the condensed liquid mixing of process secondary condenser gets into liquid storage cylinder without secondary condenser; Release heat in the process of cold-producing medium condensation in first-stage condenser and secondary condenser; Liquid refrigerant enters into evaporimeter after through expansion valve, and at this, evaporimeter is only the equipment of real generation refrigeration effect; The cold-producing medium vaporization of absorbing heat within it, thus reach the purpose of air-conditioning cooling house inner room.
Main temperature controller and auxilliary temperature controller can be used to control the degree of heating and refrigeration, are example with main temperature controller control refrigeration, when the lower cryogenic temperature of needs; When reaching better refrigeration; Can be through the control of main temperature controller, the time that the proper extension cold-producing medium stops in evaporimeter, it is more thorough that cold-producing medium is vaporized in evaporimeter; Can absorb more heat, reach better refrigeration.
Water tank is installed on condenser, the heat that the water absorptive condenser in the water tank discharges, thus temperature raises, so the under-voltage formula multi-functional fluid of this secondary seedbed source heat pump device can also provide life to use hot water.
