Abstract

Uses the steam compression type electricity heat pump the household type cold hot spot three associations for the system, belongs to the energy and the refrigeration air conditioning area of technology. Including the engine/generator, the steam compression type electricity heat pump, the haze - water heat interchanger, keeps warm the water tank, the life hot water converter and the controller. The system first through the small engine electricity generation, provides the user the basic power load. Corresponding outside climatic conditions, system by three kind of different patterns movements. Summer refrigerates the pattern movement, the electricity generation provides the electricity heat pump to carry on the refrigeration, the haze afterheat uses for to provide the life hot water load; The winter heats the pattern movement, the electricity generation provides to the heat pump carries on the heating, the heat pump and haze heat interchanger series connected way heating; Spring the autumn by the thermoelectricity Communist Party of the Soviet Union pattern movement, the heat pump does not work, provides the life hot water load using the haze afterheat. The invention has coldly, hot, electricity load supply nimble, many kinds of patterns movement, energy use factor high, changes the load ability strongly, technology mature, movement reliable, cost low, the volume is small, is suitable for the family and the small commercial place.

Description

technical field [0001] The invention relates to a combined cooling, heating and power supply system, in particular to a household-type combined cooling, heating and power supply system which has the functions of power generation, cooling, heating and hot water supply throughout the year and adopts a vapor compression electric heat pump. Refrigeration and air conditioning technology field. Background technique [0002] A technology with high utilization rate of primary energy and low emission, combined heat and power system has been widely used in large-scale heating power stations, large-scale regional centralized heating and power supply. According to different power generation devices, cogeneration systems have various forms: steam turbine power generation and intermediate extraction or tail gas waste heat utilization system, gas turbine power generation and tail gas waste heat boiler system, internal combustion engine power generation and cylinder jacket water and tail ga...
