Features of Energy Evi Air To Source Heat Pump (11kw~28kw) Heating&Hot Water, R410A
A low-temperature environment cold and warm air energy heat pump system, comprising a fin heat exchanger, a shell and tube heat exchanger and a circulation system. The circulation system includes a compressor, a four-way valve, an expansion valve, an economizer (6), and a liquid reservoir Compared with the gas-liquid separator, the low-temperature environment cold and warm air energy heat pump system of the present invention optimizes the pipeline structure, so that cooling and heating share the same casing path and components, eliminating at least two one-way valves and one expansion valve. The pipeline structure is greatly simplified without affecting the cooling and heating process, the installation and maintenance are convenient, and the manufacturing cost and labor cost are reduced. The compressor air inlet of the cold and warm air energy heat pump system in the low temperature environment of the utility model is provided with two refrigerant gas recovery pipelines, which greatly improves the heating efficiency of the compressor, and has good low temperature heating performance, which is very suitable for long heating time and low temperature. Area.
