Thermal-storage air-cooled heat pump cold-hot water integrating system

Abstract

The compressor, the water heater, the air-cooling heat exchanger, the bivalve mechanism and the heat exchanger at waterside are included in the system constitute a working cycle loop. The characters are that the water heater is added between the compressor and the air cooling heat exchanger as well as the heat storage device is parallel connected between the water outlet and backwater location. When refrigerating, the invention takes full advantage of condensation heat of gas at high pressure and high temperature at vent hole. Meanwhile, the increscent condensing surface raises ratio of energy efficiency. When producing heat, operation of accumulating heat is carried out at a valley time, and operation of releasing heat is carried out at a peak time so as to save cost. In cold weather, accumulating heat at night and supplying heat to the heat pump so as to overcome shortcoming of heat pumps unable to run effectively at cold area.

Description

【Technical field】 [0001] The invention relates to an air-cooled heat pump integrated cooling and hot water air conditioning system, in particular to a heat storage type air cooled heat pump integrated cooling and hot water air conditioning system. 【Background technique】 [0002] With the development of industry and the improvement of people's living standards, heating and cooling are inseparable in production and life, and have become crucial to urban living quarters, commercial buildings and the entire life of human beings. One of the major uses of energy in large cities is to heat and cool buildings. Traditional powertrain technology development and commercialization efforts have primarily focused on individual devices, eg, district heating, direct-fired central air-conditioning equipment. The common problem of these devices is the high energy consumption under a single target, and these devices have not achieved efficient comprehensive utilization of energy. The equipme...

The common problem of these devices is the high energy consumption under a single goal, and these devices have not achieved efficient comprehensive utilization of energy

The equipment investment and operating costs of the absorption cooling and heating integrated system directly burning natural gas are high (the price of natural gas is high), and the energy utilization rate of the system is relatively low; the traditional compression cooling and heating equipment is difficult to use independently in cold regions. Poor usability; and the direct use of electric boilers not only has poor energy utilization, but also high operating costs
