Description
Technical field
The utility model relates to a kind of freezing heat pump machine, belongs to heat pump application technical field.
Background technology
Heat pump techniques is the new energy technology received much attention in the whole world in recent years.Heat pump is that one can obtain Lowlevel thermal energy from natural air, water or soil, and through electric energy acting, providing can by the device of people's high level heat used.In recent years, because the cry of low-carbon environment-friendly is more and more surging, people also paid attention to all the more the carbon emission amount that self social activities produces.Economic model based on low energy consumption, low stain, low emission is the again major progress of human society after agricultural civilization, industrial civilization.Therefore, low-carbon (LC) theory, low-carbon (LC) life, green products and service etc. is all in succession created in every field.Heat pump may be used for refrigeration, also may be used for heating, but at present, temperature can be carried out appropriateness and raised or reduce by traditional heat pump, but cannot reach higher temperature (as 70 DEG C) or lower temperature (as-20 DEG C).
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and not only can reach freezing low temperature but also can reach boiler high temperature and the freezing heat pump machine of energy-conserving and environment-protective.
Freezing heat pump machine described in the utility model, comprises the identical low temperature group heat pump of structure and high temperature group heat pump; Often organize heat pump and include the evaporimeter, compressor and the condenser that are connected by pipeline, the outlet of condenser connects the import of evaporimeter by pipeline one, pipeline one installs throttling arrangement, cold-producing medium flows through compressor, condenser, throttling arrangement, evaporimeter in turn, flow back to compressor again, and circulate with this; Heat exchange is carried out by heat transmission equipment between the condenser of low temperature group heat pump and the evaporimeter of high temperature group heat pump.
The low temperature group heat pump of whole freezing heat pump machine operationally, the high steam of being discharged by compressor enters condenser, refrigerant vapour is condensed into liquid (heat of release is generally at about 30 DEG C), enter evaporimeter through throttling arrangement, and absorb heat in evaporimeter, outside air or refrigerating medium are cooled to about-25 DEG C (even lower), reach freezing low temperature, refrigerant vapour after evaporation is sucked by compressor, goes round and begins again like this, realizes circulation; And the heat that in low temperature group heat pump, refrigerant vapour is condensed into liquid release within the condenser passes to evaporimeter in high temperature group heat pump by heat transmission equipment, the operation principle of high temperature group heat pump is identical with low temperature group heat pump, unlike, in the condenser of high temperature group heat pump, refrigerant vapour is condensed into the heat of liquid release generally at about 85 DEG C, can be used for boiler etc.
Wherein, throttling arrangement adopts expansion valve; Cold-producing medium in low temperature group heat pump adopts R22, R404a or other cold-producing mediums; Cold-producing medium in high temperature group heat pump adopts R22, R134a or other cold-producing mediums.
The beneficial effect that the utility model is compared with prior art had is:
The utility model reasonable in design, both can reach the freezing low temperature of-25 DEG C even lower by the utility model, can reach again the boiler high temperature of 85 DEG C, energy-saving effect is remarkable.
