Energy-saving air-conditioning/hot water triple-supply system

Abstract

The invention discloses an energy-saving air-conditioning / hot water triple-supply system, comprising a compressor (1), a hot water heat exchanger (4), an air heat exchanger (6), an air conditioning heat exchanger (10) and other parts; using main components of a heat pump system, the system adopts a structure with three heat exchangers interconnected in a mixed manner and double four-way reversing valves and has four working modes including refrigeration and water heating, water heating, heating and water heating, and defrosting, thus the triple supply of refrigeration, heating and clean hot water can be realized; the system has high heat exchange efficiency and simultaneously enhances energy efficiency ratio of system as well; by adopting the heat pipe exchangers, the system solves the problem that the heat exchanger is liable to leakage so as to pollute water, and overcomes the deficiency of large resistance when a plurality of heat exchangers are connected with each other in series.

Description

technical field [0001] The invention relates to a heat pump type air conditioner and hot water system, in particular to an efficient and energy-saving air conditioner and hot water system capable of realizing combined supply of refrigeration, heating and sanitary hot water. Background technique [0002] At present, my country's air-cooled heat pump air-conditioning equipment and air-source heat pump hot water equipment are basically two kinds of independent equipment. Conventional air-cooled heat pump air-conditioning equipment can only provide cooling and heating, while the air-source heat pump developed in recent years Although the hot water unit is an energy-saving device, it only provides sanitary hot water; although there are research reports that the waste heat discharged from the electric compression air conditioner can be used to produce sanitary hot water, but only when the air conditioner is used for cooling, hot water can not be produced. Solve the problem of hot wa...
