Abstract

A flexible gas engine driving type compression type heat pump system with an after-burning device is mainly composed of a flexible heat pump circulation system and an after-burning type waste heat circulation system; a heat source side heat exchanger of the flexible heat pump circulation system is connected with one cooling tower and not less than two fin type heat exchangers in parallel; intermediate heat exchanging media take heat from a low-temperature environment through the not less then two fin type heat exchangers; the after-burning type waste heat circulation system utilizes engine waste heat, and can provide high-temperature hot water all year around; the after-burning device is started when heating in winter is not sufficient, and heat generated by the after-burning device and the engine waste heat assist in refrigerating agent evaporation together through a plate type heat exchanger; when the fin heat exchangers are in frosting operation, the heat of the after-burning deviceand the engine waste heat perform alternate defrosting on the fin heat exchangers, and continuous and stable heating is guaranteed; and the flexible gas engine driving type compression type heat pumpsystem effectively solves the problems that an air source heat pump is low in refrigerating energy efficiency in summer and has a chronic disease of defrosting and insufficiency of the heating capacity in winter.

Description

technical field [0001] The invention relates to a flexible gas engine-driven compression heat pump system with a supplementary combustion device, in particular to an exhaust gas supplementary combustion flexible heat pump system that uses increased flue gas displacement to assist evaporation and alternate defrosting, and belongs to the technical field of heat pumps. Background technique [0002] A heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source to a high-level heat source. As the low-grade heat source of the heat pump, air is inexhaustible and can be obtained for free, and the installation and use of air source heat pumps are More convenient. At the end of the 1980s, the research on air source heat pumps in my country has developed rapidly, but the air source heat pumps will have insufficient heating capacity and frosting problems when they operate at low temperatures in winter. Aiming at this situation, a flexi...
