A vapor pressure up-and-down adsorption method and a heat pump using the method

Abstract

The invention provides a steam pressure lifting adsorption method. Currently, mature heat pumps mainly have two types including an electric-driven mechanical compressing system and a liquid-gas absorption system; both the two systems have defects, the mechanical compressing system is power-energy consuming, high in equipment investment, high operation cost and restricted in large-scale application, and the liquid-gas absorption system affected by low efficiency is large in equipment size and poor in economic efficiency; due to characteristics of refrigerant, absorber, mechanical equipment and system techniques, low heat-pump output temperature is the common problem of existing heat pumps. The steam pressure lifting adsorption method by which substantial waste heat can be fully utilized is provided to overcome the defects. The invention further provides a steam pressure lifting adsorption pump. By the steam pressure lifting adsorption pump which transmits heat and directly introduces waste-heat steam as circulatory media according to the steam pressure lifting adsorption method, heat transmission steps and system equipment composition are simplified, and the problems of low-grade waste-heat steam utilization and about energy conservation are solved.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization and energy saving, specifically a steam pressure lifting adsorption method, and the invention also provides a steam pressure lifting adsorption heat pump using the method to transfer heat. Background technique [0002] At present, there are mainly two types of mature heat pumps: one is an electric-driven mechanical compression system, and the other is a liquid-vapor absorption system. However, both of these methods have disadvantages. The mechanical compression type needs to consume electric energy, and the equipment investment is large, the operating cost is high, and the large-scale application of the system is limited. The liquid-vapor absorption system is affected by low efficiency, huge equipment, and relatively poor economy. Due to the characteristics of refrigerant, absorbent, mechanical equipment and system technology, the common problem of existing heat pumps is that the o...

But both of them have disadvantages. The mechanical compression type needs to consume electric energy, which requires large equipment investment and high operating costs, and the large-scale application of the system is limited.

The liquid-vapor absorption system is affected by low efficiency, huge equipment, and relatively poor economy

Due to the characteristics of refrigerant, absorbent, mechanical equipment and system technology, the common problem of existing heat pumps is that the output temperature of heat pumps is not high. For the large amount of waste heat steam existing in metallurgy, chemical industry, building materials, electric power and other industries, traditional heat pumps can be used to improve The output temperature is quite difficult, so that the waste heat steam cannot be widely used, and a large amount of waste heat is wasted
