Abstract

The invention discloses an ammonia water absorption-compression type composite heat pump driven by double heat sources of solar energy and fuel gas, and belongs to the field of solar heat utilizationand heat pump air conditioners. The composite heat pump comprises a generator high-temperature section, a generator medium-temperature section, a generator low-temperature section, a rectifier, a condenser, a subcooler, a throttle valve A, an evaporator, a three-way valve A, a compressor, a solution cooling absorber, a water cooling absorber, a throttle valve B, a solution circulating pump, a gasfurnace, a three-way valve B, a solar heat collector, a heat collector working medium circulating pump, a heat collector working medium circulating pipeline, a heating water return port, a heating water outlet, a compressor bypass pipe and a heat collector working medium bypass pipe. The composite heat pump is applied to northern winter heating, improves a winter heating structure mainly using fire coal, and adopts clean energy to improve the environment.

Description

technical field [0001] The invention relates to the field of solar heat utilization and heat pump air conditioning, in particular to an ammonia water absorption-compression composite heat pump driven by solar energy and gas dual heat sources. Background technique [0002] With the intensification of the energy crisis and the improvement of environmental protection requirements, energy-saving and emission-reduction technologies have become a worldwide research topic. China is energy consumption and CO 2 Large emission countries are facing increasingly severe pressure on energy conservation and emission reduction. At the same time, the smog problem closely related to the coal-based energy consumption pattern has attracted increasing attention. [0003] In the cold northern regions of my country, building heating energy consumption accounts for more than 50% of the total building energy consumption. The serious smog problem is mainly attributed to the unclean heating method m...
