Heat source tower heat pump

Abstract

The invention provides a heat tower heat pump, mainly consisting of a cold / heat source absorption device closed heat tower and a low-temperature heat tower elevating device low-temperature heat source heat pump. The invention can be used as an efficient water evaporation cooling device in summer and an efficient broadband frost-free air source heat pump in winter, realizing cooling in summer and heating in winter, capable of supplying hot water for households; thereby the invention can be used for the three purposes.

Description

technical field [0001] The present invention relates to a cooling and heating device, in particular to a cooling and heating device composed of a cold heat source tower and a low heat source heat pump, which is suitable for use in buildings under the environmental conditions of "low temperature and high humidity" in winter- Heat source tower heat pump. Background technique [0002] In winter, in the area south of the Yangtze River Basin in China, the cold air from the north flows southward. When it flows to the southwest, it is completely blocked by the Yunnan Plateau and the Western Sichuan Plateau at an altitude of about 3,000 meters. However, the warm and humid air from the South China Sea and the Bay of Bengal continue to pass over the lower Nanling Mountains and merge with the cold air, making the vast southern area between the three mountain ranges often become a stagnant area for cold and warm air masses. Continuous rain, "low temperature and high humidity" has becom...

AI Technical Summary

Problems solved by technology

However, its ground source heat pump adopts a mixed source heat pump (soil source + cooling tower), which is only suitable for use in the northern United States where the temperature of the underground soil source is more than ten degrees below zero in winter.

[0005] However, the geological structure in southern China is complex, and the rock formations in many hilly and mountainous areas are buried shallowly. The mixed source heat pump (soil source + cooling tower) is used, and the initial investment cost of the underground soil source is expensive.

However, the buildings in the central area of ​​the city can meet the laying conditions of mixed-source soil-source heat exchangers, almost zero. Therefore, a large number of electric heating, oil-fired, and coal-fired boilers are used as heating sources, which not only consumes high energy, but also causes environmental pollution. quite serious
