Therefore need a kind of novel heat pump type air conditioning system of design, meet and reduce power consumption, can also adapt to various areas simultaneously and use, cost is also relatively cheap.
Summary of the invention
The present invention proposes a kind of heat pump based on the ice source heat pump technology, has reduced the heat pump type air conditioning system cost, can also adapt to various areas simultaneously.
Technical scheme of the present invention is achieved in that a kind of heat pump based on the ice source heat pump technology, the ice source heat pump main frame and the room conditioning end that comprise cooling tower, be comprised of reservoir and compressor, be equipped with heat exchanger between described cooling tower and ice source heat pump main frame and between ice source heat pump main frame and room conditioning end.
Further, described heat exchanger adopts two kinds of independent loops system type heat exchangers of refrigerating medium-cold-producing medium.
Further, described heat exchanger one side interface respectively at the inlet of cooling tower with liquid outlet, be connected, the opposite side interface is connected with water inlet and the reservoir of compressor; Described another one heat exchanger one side interface is connected with delivery port and the reservoir of compressor, and the opposite side interface is connected with the room conditioning end.
Further, between described reservoir and two heat exchangers, all be connected with the electronic expansion choke valve.
Further, between described reservoir and two heat exchangers, also be connected with the check valve parallel with the electronic expansion choke valve.
Further, also comprise the commutation cross valve, in described commutation cross valve, be divided into two groups of not connected pipelines, and with the inlet of compressor, be connected with liquid outlet respectively.
Beneficial effect of the present invention is: the heat pump based on the ice source heat pump technology of the present invention, by in the antifreeze circulatory system, adding anti-freezing water solution, this solution can not freeze in the time of subzero 20 ℃, and weather environment can season oneself to cold, liquid can not freeze, and is indoor heating for transferring heat energy.Ice source heat pump utilizes water to supply with the condensation water of heat pump below 30 ℃ at evaporative cooling in cooling tower summer, utilize winter frozen water solution below freezing tow taste heat by cooling tower absorbing environmental air to heat pump, obtain high-grade heat energy for the user.Do not need again defrosting winter, lasting efficient stable heats, and heating efficiency is high.Ice source heat pump structure is simple, does not select geographical position, and the center, big city all can be installed, and system cost is cheap, utilizes us containing the energy that capacity is huge---environment thermal energy at one's side.It is most economical, the most practical, the most inexhaustible regenerative resource.Ice source heat pump is actually the thermal gradient energy of extraction environment, just can become available thermal energy to useless environment thermal energy, produce hot-air required in production and life, hot water etc., ice source heat pump has been opened below 0 ℃ does not just have hot traditional consciousness, as long as in fact there is the temperature difference just can obtain heat.Application and the popularization of ice source heat pump, just be equivalent to open this infinite capacity of environment thermal energy, available, the brand-new energy Bao Kuang of regeneration at any time everywhere.
