Description
Technical field
The utility model relates to marine air-conditioning system, is a kind of air-cooled heat pump type handpiece Water Chilling Units peculiar to vessel specifically.
Background technology
The superheated steam that common wind-cooled cold-water unit peculiar to vessel is is high temperature, high pressure by the refrigerant vapor compression of low-temp low-pressure enters in air-cooled condenser; Enter the high-temperature high-pressure refrigerant gas of air-cooled condenser, carry out heat exchange with extraneous cooling medium, emit heat, thereby refrigerant gas is condensed into still higher liquid of the not high and pressure of temperature gradually; Expenditure and pressure when condensed high pressure saturated liquid process heating power expansion valve; After refrigerant pressure and temperature decrease, enter dry evaporator, absorb the heat through chilled water in the circulation of dry evaporator appearance, chilled water temperature is reduced, low temperature chilled water is sent in packaged air conditioner peculiar to vessel and carries out cooling to air, thereby cabin temperature is reduced, cold-producing medium itself becomes steam because absorbing heat by liquid evaporation simultaneously, then sucked by compressor, after recompressing into the gas of high temperature, high pressure, enter in air-cooled condenser, thereby complete a circulation, utilize this circulation going round and beginning again to reach the object of refrigeration.In the time that need to heat winter, on ship, needing to provide in addition a set of equipment thermal source to be provided or to increase electric heater in indirect type air-conditioner peculiar to vessel to indirect type air-conditioner heats, air-conditioner and electrical heating optional equipment take hull space, and equipment cost and use cost increase.
Summary of the invention
Meet respectively the deficiency of refrigeration, heating condition requirement for two complete equipments of marine air conditioner in prior art, it is a kind of simple in structure, easy to use that the utility model provides, need not optional equipment, can take into account refrigeration peculiar to vessel and heat requirement, the air-cooled heat pump type handpiece Water Chilling Units peculiar to vessel that use cost is low.
The technical solution adopted in the utility model is: a kind of air-cooled heat pump type handpiece Water Chilling Units peculiar to vessel, comprise compressor, air-cooled condenser, oil conservator, expansion valve and plate type heat exchanger, its technical characterstic is the outlet of described compressor connects respectively air-cooled condenser, compressor import and plate type heat exchanger one channel outlet through four-way change-over valve, and four-way change-over valve is any two-way and connects other two-way on-states simultaneously; Air-cooled condenser is successively through oil conservator and expansion valve connecting plate type heat exchanger one channel entrance, and expansion valve is Bidirectional expansion valve, and another passage import and export of plate type heat exchanger connects chilled water into and out of pipe.
Further, described oil conservator is provided with safety valve.
Further, between described air-cooled condenser and Bidirectional expansion valve, be provided with device for drying and filtering.
Again further, between described air-cooled condenser and Bidirectional expansion valve, be provided with and look filter.
Adopt above technical scheme, the beneficial effects of the utility model are: this handpiece Water Chilling Units is in the time of refrigerating operaton, cold-producing medium exports through compressor, four-way change-over valve is delivered to air-cooled condenser, carry out heat exchange with extraneous cooling medium, condensed cold-producing medium enters plate type heat exchanger through Bidirectional expansion valve expenditure and pressure, absorb through being back to compressor inlet by four-way change-over valve after chilled water heat in the circulation of plate type heat exchanger appearance, chilled water exothermic temperature in plate type heat exchanger reduces, low temperature chilled water is sent in marine air conditioner device and carries out cooling to air, thereby cabin temperature is reduced, when heating operation, cold-producing medium is compressed into the superheated steam of HTHP and delivers to plate type heat exchanger through four-way change-over valve, carry out heat exchange with the chilled water in the circulation of surface, chilled water endothermic temperature raises into heat medium water, heat medium water is delivered in marine air conditioner device air is heated, thereby cabin temperature is raise, enter air-cooled condenser through the condensed cold-producing medium of plate type heat exchanger through Bidirectional expansion valve, then turn back to compressor inlet through four-way change-over valve, one completes thermal source is provided winter, and the requirement of low-temperature receiver is provided summer.
The utility model adopts four-way change-over valve to switch the requirement that provides thermal source, low-temperature receiver for meeting of making of air-cooled condenser and plate type heat exchanger, effectively solve common wind-cooled cold-water unit low-temperature receiver can only be provided, the problem that need another gain of heat source device to heat winter, this set structure is simple, need not be convenient to hull installation by optional equipment, easy to use, cost-saving.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: compressor 1, four-way change-over valve 2, air-cooled condenser 3, oil conservator 4, safety valve 5, device for drying and filtering 6, depending on filter 7, Bidirectional expansion valve 8, plate type heat exchanger 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1, a kind of air-cooled heat pump type handpiece Water Chilling Units peculiar to vessel comprises compressor 1, four-way change-over valve 2, air-cooled condenser 3, oil conservator 4, safety valve 5, device for drying and filtering 6, looks filter 7, Bidirectional expansion valve 8 and plate type heat exchanger 9.The outlet of compressor 1 connects respectively import and plate type heat exchanger 9 one channel outlet of air-cooled condenser 3, compressor 1 through four-way change-over valve 2, four-way change-over valve 2 is any two-way and connects other two-way on-states simultaneously, air-cooled condenser 3 successively through oil conservator 4, device for drying and filtering 6, look filter 7 and Bidirectional expansion valve 8 connecting plate type heat exchanger 9 one channel entrances, oil conservator 4 is provided with safety valve 5, and plate type heat exchanger 9 another passage import and exports connect chilled water into and out of pipe.
This air-cooled heat pump type handpiece Water Chilling Units peculiar to vessel be in the winter time with use same set of handpiece Water Chilling Units summer, not only can in the time of refrigeration, low-temperature receiver be provided but also thermal source can be provided in the time heating, effectively reduce marine electric load, save energy consumption, economical operation.
