Abstract

The invention provides a cold water phase transformation machine assisted energy tower heat pump system, and belongs to the technical field of energy sources. The invention aims to provide a cold water phase transformation machine assisted energy tower system. Sensible heat and latent heat in water are extracted by using a cold water phase transformation machine to serve as an assisted heat source; the heating capacity of the system is ensured, so that the problem is solved that the heating energy consumption of the energy tower is too high in winter, and the heating capacity is reduced at night; and it is achieved that the heating system supplies heat stably for a long time. The invention is applicable for a cold water phase transformation machine assisted energy tower heat pump heating or cooling system.

Description

technical field [0001] The patent of the invention relates to a cold water phase change machine auxiliary energy tower heat pump system, which belongs to the field of energy technology. Background technique [0002] The proportion of HVAC energy consumption in the total building energy consumption in my country is increasing day by day, and the resulting environmental problems are becoming more and more serious. Therefore, heat pump technology that focuses on environmental protection and energy saving has gradually received attention. The energy tower heat pump uses air as a low-grade energy source, and is not restricted by geographical conditions such as soil and water sources. It is suitable for large-scale public buildings in most areas, and there is no frost problem in winter, and it can operate efficiently as a cooling tower in summer. [0003] The heat pump system of the energy tower is used for heating. When the outdoor air temperature is extremely low in winter, the ...
