Cold and heat combined supply system of heat pump

Abstract

The invention discloses a cold and heat combined supply system of a heat pump. The cold and heat combined supply system of the heat pump comprises the heat pump, a refrigerating chamber and a heat / cold storage water tank, wherein the heat pump is provided with a heat pump first input end, a heat pump second input end and a heat pump output end; the refrigerating chamber is separately connected with the heat pump first input end and the heat pump second input end; a refrigerating chamber air-inlet regulating valve and an evaporator outdoor air air-inlet regulating valve are arranged between therefrigerating chamber and the heat pump first input end; a refrigerating chamber air-return regulating valve and an evaporator outdoor air air-exhasut regulating valve are arranged between the refrigerating chamber and the heat pump second input end; the refrigerating chamber air-inlet regulating valve, the refrigerating chamber air-return regulating valve, the evaporator outdoor air air-inlet regulating valve and the evaporator outdoor air air-exhasut regulating valve are used for regulating cold / heat loads needed for regulating the refrigerating chamber; and the heat / cold storage water tankis connected with the heat pump output end. The cold and heat combined supply system of the heat pump disclosed by the invention can improve indoor environmental comfort while realizing cold and heatcombined supply, energy saving and emission reduction.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a heat pump combined cooling and heating system. Background technique [0002] Under the dual pressure of human energy crisis and environmental crisis, energy conservation and emission reduction has become a topic of much concern. The north is comprehensively promoting the "coal-to-electricity" heating transformation. Through the transformation of heating methods, the main cause of smog is cut off from the source. Air source heat pumps have become the first choice in the implementation of “coal to electricity” in the north because of their energy saving and high efficiency. [0003] With the improvement of people's living standards, the requirements for the comfort of the indoor environment are getting higher and higher. For the heating renovation process in the north, how to achieve energy saving and low carbon while improving indoor comfort has attracted more and more attentio...

Problems solved by technology

With the verification of a large number of engineering examples, this kind of household independent heating has the problems of only changing the heat source, not changing the end, the design heating capacity of the unit is too large, and the unit is unstable at low temperature, and the room is not hot; the power increase is large, and the investment is relatively large. Large and unstable power grid; units cannot be operated, maintained, and managed in a centralized manner; units are idle in summer, and cooling capacity is wasted while generating heat in winter, and there is room for improvement
