Abstract
Disclosed is a phase change heat storage unit. A rotating compressor 1, a brazing plate heat exchanger 2, a throttling component 5 and a finned heat exchanger 4 form a refrigerant circulating system of an air source heat pump. A pipeline pump 7, the brazing plate heat exchanger 2, a heat storage tank 3 and a brazing plate heat exchanger 6 form a heat absorption, heat storage and heat emission process. Running water of the use side is subjected to heat transfer with the brazing plate heat exchanger 6 to finally produce domestic hot water. The unit combines the air source heat pump and the heat storage technology, high efficiency and environmental protection of the air source heat pump are combined, the measure of peak load shifting is taken, the peak load part is shifted to a valley period by means of peak load shifting, power grid load of periodic fluctuation is more balanced, power resource configuration is optimized, efficiency and benefit of power supply are increased, energy resources are saved, cost of power utilization is lowered, and the phase change heat storage unit is of great significance to power utilization enterprises and social and economic development.
Description
Technical field
The present invention relates to air-conditioning technical field, especially a kind of phase-transition heat-storage unit.
Background technology
Along with the development of Chinese national economy and the raising of living standards of the people, cities and towns power consumption constantly increases, and electric power peak-valley difference constantly expands, and particularly the development of the tertiary industry and resident's air-conditioning is universal, the peak valley contradiction of having aggravated power supply.For ensureing the safe operation of electrical network, utilize better limited electric power resource, safeguard the normal electricity consumption order that supplies, ensure numerous clients' interests, alleviate the impact that power shortage brings socio-economic development and people's lives, take peak load shifting measure just seem necessary and advocated.The present invention caters to peak load shifting measure just, utilize night power driven compressor unnecessary and at a low price to carry out air source heat pump process, the hot water heat that heat pump process produces passes to phase transition heat accumulation unit and stores, and daytime, release heat out added hot tap-water for use side again.
Current phase transition heat accumulation unit efficiency is lower, can not widespread adoption.
Summary of the invention
The present invention, in order to solve the technical problem of above-mentioned existence, provides a kind of phase-transition heat-storage unit.
Technical scheme of the present invention is achieved in that
A kind of phase-transition heat-storage unit, is made up of the refrigerant-cycle systems of air source heat pump rotary compressor 1, brazing plate type heat exchanger 2, orifice union 5, finned heat exchanger 4; Formed the process of heat absorption-accumulation of heat-heat release by tubing pump 7, brazing plate type heat exchanger 2, heat storage tank 3, brazing plate type heat exchanger 6; The running water of last use side finally produces domestic hot-water by carrying out heat transmission with brazing plate type heat exchanger 6.
In the present invention, brazing plate type heat exchanger 2 and brazing plate type heat exchanger 6 are stainless steel plate type heat exchanger, adopt stainless steel plate type heat exchanger can improve heat exchanger efficiency, guarantee the heat source of hot water that provides stable.
In the present invention, between brazing plate type heat exchanger 2 and orifice union 5, be provided with filter, prevent that orifice union from stopping up, thereby ensure that refrigeration system provides stable thermal source hot water.
In the present invention, between rotary compressor 1 and brazing plate type heat exchanger 2, be provided with high-pressure switch, between rotary compressor 1 and finned heat exchanger 4, be provided with low pressure switch, when the pressure in pipe-line system is during higher or lower than safe pressure, high-pressure switch and low pressure are switch activated, and equipment is quit work; In the time that the pressure in pipe-line system is returned to the safe pressure scope of equipment, high-pressure switch or low pressure switch reset equipment are normally worked.High-pressure switch and low pressure switch have prevented hypertonia in pipe-line system or too low, thereby ensure that pipe-line system works all the time in the working pressure range of safety.
The regenerative apparatus that heat storage tank 3 in the present invention is special material, it can fill part and absorb the thermal source heat that evening, electric energy drive compression machine carried out the production of air source heat pump process at a low price, and the water that makes that passes to client uses.
The present invention is a kind of unit of air source heat pump+heat storage technology, both combined the efficient and environmental protection of air source heat pump, utilize again peak load shifting measure, by peak load shifting, peak load part is transferred to low ebb period, make the network load of cyclic fluctuation become more balanced, optimized electric power resource configuration, efficiency and the benefit of supply of electric power are improved, save the energy, finally reduce electric cost, to electricity consumption enterprise
,socio-economic development is had to great meaning.
