Heat pump air conditioning device with outdoor air heat exchangers flexibly arranged

Abstract

The invention discloses a heat pump air conditioning device with outdoor air heat exchangers flexibly arranged. The heat pump air conditioning device comprises an indoor unit and the at least one outdoor air heat exchanger; the outdoor air heat exchangers are flexibly arranged outdoors; the indoor unit comprises a compressor, a four-way reversing valve, an indoor heat exchanger, a throttling valveand a liquid pump; the compressor, the four-way reversing valve, the indoor heat exchanger, the throttling valve and the liquid pump in the indoor unit and the outdoor air heat exchangers form a heatpump circulation system together; and the outdoor air heat exchangers adopt flat plate shapes, are combined or are flexibly arranged leaning on a building exterior wall, a parapet wall and a roof. The heat pump air conditioning device has the advantages that the outdoor air heat exchangers and a building are integrated into a whole, and therefore the outdoor space occupied by installation can begreatly reduced; and in addition, the area of the outdoor air heat exchangers can be increased by adopting a parallel connection mode, the indoor unit can be matched with the large compressor, and therefore the refrigerating and heating efficiency can be improved, the energy consumption of cooling and heating can be reduced, in addition, the equipment cost of the unit refrigerating and heating load can be lowered, and the application range of an air-cooling air conditioner can be greatly widened.

Description

technical field [0001] The invention relates to the technical field of air-cooled heat pump air conditioners, in particular to a heat pump air conditioner with outdoor side air heat exchangers flexibly arranged. Background technique [0002] At present, with the improvement of people's living standards in our country, the requirements for indoor comfort are getting higher and higher, and the energy consumption of building cooling and heating has increased significantly. Vigorously developing building energy-saving technologies is an important means to achieve sustainable development; in addition, my country Air pollution is relatively serious, and coal-fired heating for buildings in winter is an important factor that pollutes the air. Therefore, the country vigorously advocates clean heating methods such as "coal-to-electricity" and heat pumps are the most efficient and reasonable technical means for electric heating. Air-source heat pump air conditioners are highly efficient ...

AI Technical Summary

Problems solved by technology

However, the current air source heat pump air conditioners are basically small modules, which can only be installed outdoors as a whole. Moreover, the cooling and heating capacity of a single module is very small, and the number of modules is large, which occupies too much outdoor space of the building and affects the appearance of the building. In addition, the efficiency of small compressors is relatively low, which greatly affects the popularization and application of air source heat pump air conditioners
