Abstract

The invention discloses a multifunctional cold and heat combined supply heat pump system which comprises a draught fan, a water distributing device, a material filling area, a shutter, a strut, a water heating tank, a heat-end heat exchanger, a check valve, a first condenser, a first compressor, a first evaporator, a second condenser, a second compressor, a second evaporator, a cold-end heat exchanger, a cold supply area, a heat exchange tower, a tap water storing tank, a three-way valve, a concentrated salt water storing tank, a first expanding valve, a second expanding valve, a valve, a water pump and a pipeline connecting system. Two heat pumps adopt a serial and parallel connection adjustable pipeline system and a circulation working medium adjustable heat exchange tower system, thereby solving the problem of frosting of the evaporators in winter and the problem of great reduction of the running efficiency of the heat pumps in extreme climate and leading a cold and heat combined supply heat pump to efficiently run in various climates; and the system can be used for large public systems, such as hotels, factories, stores, and the like and greatly widens the application range ofthe heat pump system.

Description

technical field

[0001] The invention relates to a heat pump system, in particular to a multi-functional combined cooling and heating heat pump system. Background technique

[0002] Environmental pollution and energy crisis have become two major problems in today's society. Our country has taken "energy saving and emission reduction" as a basic strategy alongside economic development. Unreasonable energy structure and inefficient use of energy not only affect the economic construction and development of our country, but also affect the surrounding environment on which we live. In recent years, with the vigorous development of hotel buildings, the energy consumption in hotel buildings has become more and more serious. According to the investigation of related literature, it not only brings huge pressure to energy, environmental protection and other causes, but also puts great pressure on hotel buildings. operators with no small economic impact. The energy consumption of some...
