Direct-fired absorption type air source heat pump circulating heating system

Abstract

The invention belongs to the field of heating, ventilation and air conditioning, and particularly relates to a direct-fired absorption type air source heat pump circulating heating system. The heatingsystem is suitable for being used as a clean heating mode for winter living and public buildings in most areas such as northern China and the middle and lower reaches of the Yangtze River. The systemcomprises three basic modules, namely, a direct-fired absorption type heat pump circulation module, a vapor compression type air source heat pump module and a user heating module. The direct-fired absorption type heat pump circulation module and the vapor compression type air source heat pump module are coupled through an evaporator / condenser, the vapor compression type air source heat pump module is used to prepare a low-temperature heat medium, and the heat medium provides a stable and suitable low-temperature heat source for the direct-fired absorption type heat pump circulation module through the evaporator / condenser. The direct-fired absorption type air source heat pump circulating heating system overcomes the defects of low energy utilization efficiency, heavy pollution and the likeof a traditional heating mode, fully utilizes the high-grade property of gas energy, greatly reduces the gas demand and has the beneficial effects of being compact in structure, small in occupied area, high in energy utilization efficiency, low in operation cost and the like.

Description

technical field [0001] The invention belongs to the field of heating, ventilating and air conditioning, and particularly relates to a direct-fired absorption air source heat pump circulation heating system, which is suitable as a clean heating method for residential buildings and public buildings in most areas in northern my country and the middle and lower reaches of the Yangtze River. Background technique [0002] In recent years, with the improvement of living standards and the expansion of building areas, the energy consumption of heating and air conditioning in buildings has increased sharply, and the resulting environmental pollution has become increasingly serious. Coal to clean energy heating is the fundamental way to solve my country's energy and environmental problems. Replacing coal-fired boilers with gas-fired boilers and air-source heat pumps are currently the two main technical means to achieve clean heating. However, the current heating of gas-fired boilers ha...
