Household cold, heat and power triple supply system adopting vapor compression type electrothermal pump

Abstract

The utility model relates to a household combined cooling, heating and power supply system using a vapor compression electric heat pump, which belongs to the technical field of energy and refrigeration and air conditioning. Including engine / generator, vapor compression electric heat pump, flue gas-water heat exchanger, heat preservation water tank, domestic hot water heat exchanger and controller. The system first generates electricity through a small engine to provide the user's basic electrical load. The system operates in three different modes corresponding to the external climatic conditions. In summer, it operates in cooling mode, and the power is supplied to the electric heat pump for cooling, and the waste heat of the flue gas is used to provide domestic hot water load; in winter, it operates in the heating mode, and the power is supplied to the heat pump for heating, and the heat pump and the flue gas heat exchanger are connected in series to provide heat ; In spring and autumn, it operates in the mode of combined heat and power, the heat pump does not work, and the waste heat of flue gas is used to provide domestic hot water load. The invention has the advantages of flexible cooling, heating and electric load supply, multi-mode operation, high energy utilization rate, strong load variable capacity, mature technology, reliable operation, low cost and small size, and is suitable for families and small commercial places.
