Abstract

The invention discloses a dual heat-source heat-pump hot water device with an extremely simple refrigerating loop. The device is characterized by mainly comprising a compressor, a hot water condenser, a wind heat exchanger, a water heat exchanger, a four-way valve, a bidirectional throttle and the like, wherein a high pressure inlet of the four-way valve is connected with the outlet of the hot water condenser, and the other three ports thereof are connected with air inlets of the wind heat exchanger, the water heat exchanger and the compressor respectively; other ports of the wind heat exchanger and the water heat exchanger are connected with the bidirectional throttle; the exhaust port of the compressor is connected with the inlet of the hot water condenser, and is connected with high pressure air inlet of an electromagnetic pilot valve of the four-way valve; four functions of manufacturing hot water by utilizing water source or air energy and providing air-conditioning cool water by utilizing air-cooling or heating water can be realized by only switching the four-way valve, defrosting can be performed completely and quickly; and a water pre-heater is added to the device to reclaim the heat of waste hot water. The heat pump has the advantages of dual heat sources compensation and wide application range, has multiple functions, extremely simple structure, extremely convenient switching and over 5 of annual comprehensive energy efficiency ratio, and has great popularization value.

Description

Technical field:

[0001] The invention relates to the technical field of heat pump water heaters. Background technique:

[0002] Heat pump water heaters use air or water as the heat source, through the refrigeration cycle of compression and boosting of refrigerant vapor, condensation and heat release, throttling reduction, evaporation and heat absorption, the compressor consumes a small amount of high-grade electric energy, and converts a large amount of zero-grade air energy or Sensible heat in low-grade water can increase the temperature and heat domestic water. Compared with consuming high-grade fuel or electric energy to heat water, it has obvious energy-saving effects; the energy efficiency ratio of general heat pump water heaters is 3-4. Most of the current heat pump water heaters are single heat source heat pumps. Single heat source heat pumps have their limitations. For air heat source heat pumps that use air energy as the single heat source, the pressure of the heat...
