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

Abstract

A regenerative air-cooled heat pump integrated cold and hot water system, including a compressor, a water heater, an air-cooled heat exchanger, a double valve mechanism, and a water-side heat exchanger to form a closed working cycle loop. There is a water heater between the exchangers, which is characterized in that a heat storage device is connected to the hot water outlet and return of the unit. The invention makes full use of the condensation heat of the high-pressure and high-temperature gas at the air outlet during refrigeration, improves the effective utilization rate of energy, increases the condensation area on the basis of increasing the water heater, reduces the condensation temperature, and effectively improves the energy efficiency ratio of the system; , heat storage is carried out through the operation of the heat pump unit during valley electricity, and heat is released during peak electricity, which effectively reduces the user's operating costs; To ensure the normal heating operation of the heat pump, it overcomes the drawbacks that the heat pump cannot operate effectively in cold regions.

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
