VM (Vuilleumier) cycle heat pump type air-conditioning water heater driven by industrial exhaust heat

Abstract

The invention relates to a VM (Vuilleumier) cycle heat pump type air-conditioning water heater driven by industrial exhaust heat, which is used for solving the problems of refrigerating and heating by sufficiently utilizing industrial exhaust heat. The technical scheme of the invention is that: the VM cycle heat pump type air-conditioning water heater comprises a VM cycle heat pump device, an industrial exhaust heat utilization device, an indoor heat exchanger, an outdoor heat exchanger, a refrigerant-water double-pipe heat exchanger, a water storage tank and a cutoff valve, a three-way valve, a fourth-way valve and a connecting pipeline; a heat pipe type interchanger of the industrial exhaust utilization device is arranged between a hot cylinder and a heat regenerator of the VM cycle heat pump device; and the VM cycle heat pump device, the indoor heat exchanger, the outdoor heat exchanger, the refrigerant-water double-pipe heat exchanger, the water storage tank and the cutoff valve, the three-way valve, the four-way valve and the connecting pipeline constitute refrigerating and heating loops in different modes. According to the invention, an industrial exhaust heat recovery technology and a VM cycle heat pump technology are combined, and the purposes of refrigerating and heating by using the industrial exhaust heat as an energy to drive a VM cycle heat pump to work are achieved; and the VM cycle heat pump type air-conditioning water heater can widely make use of various industrial exhaust heat, thereby improving the energy source utilization rate.

Description

technical field [0001] The invention relates to a VM cycle heat pump system, in particular to a VM cycle heat pump device driven by industrial waste heat to realize a triple supply system of cooling, heating and heating, and belongs to the technical field of heat exchange. Background technique [0002] With the rapid development of industrial technology and the continuous increase of energy consumption, energy shortage has become a worldwide problem. At the same time, industrial waste heat contains a large amount of unused energy, and there is a lot of room for improvement in resource utilization. For example, the waste heat available in the metallurgical industry accounts for about 33% of its fuel consumption, building materials account for about 40%, machinery manufacturing and processing industries account for about 15%, chemical, glass, and enamel industries account for more than 15%, and paper and wood industries account for about 15%. 17%, and the textile industry acc...

Problems solved by technology

At present, affected by the limitation of energy-saving technology and equipment level and the awareness of energy-saving, there are still a large number of medium and high-temperature waste heat resources that are not fully utilized in kiln industrial enterprises, and 30%-90% of the heat is discharged into the environment, which not only causes It has caused serious energy waste, and caused serious environmental heat pollution, which has exacerbated the urban "heat island effect".
