Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] Such as figure 1 The shown air source heat pump hot water unit includes a compressor 1, a four-way valve 2, a condenser 25, a liquid storage tank 8, an expansion valve 9, an evaporator 10, and a gas-liquid separator 12, which are sequentially connected and form a circuit. One end of the condenser 25 is connected with a water inlet pipe 22, and the other end of the condenser 25 is connected with a water storage tank 20 through a hot water outlet pipe 24. The condenser 25 includes at least two heat exchangers connected in series, and the other end of the condenser 25 is circulated The heating water inlet pipe 23 is connected with the water outlet of the water storage tank 20 . The condenser 25 includes a first helical casing heat exchanger 3, a second helical casing heat exchanger 4, a third helical casing heat exchanger 5, and a fourth he...

Abstract

The invention relates to the technical field of refrigerating and heating equipment, in particular to a high-temperature and high-efficiency air source heat-pump water heating unit. The air source heat-pump water heating unit comprises a compressor, a four-way valve, a condenser, a liquid storage tank, an expansion valve, an evaporator and a gas-liquid separator which are connected in sequence into a loop, wherein one end of the condenser is connected with a water inlet pipe; the other end of the condenser is connected with a water storage tank through a hot water outlet pipe. The air source heat-pump water heating unit is characterized in that the condenser comprises at least two heat exchangers which are connected in series; the other end of the condenser is connected with the water outlet of the water storage tank through a circular heating water inlet pipe. The air source heat-pump water heating unit has the advantages of high efficiency and energy saving, and the high-temperature hot water of over 80 DEG C can be produced directly.

Description

technical field [0001] The invention relates to the technical field of refrigeration and heating equipment, in particular to a high-temperature and high-efficiency air source heat pump water heater unit. Background technique [0002] Existing air source heat pump water heaters generally only have one heat exchanger for cooling. During operation, the water only exchanges heat with one heat exchanger to heat the water. In actual use, there is still a considerable part of the waste heat on the refrigerator that cannot be absorbed by the water. absorption, resulting in a waste of electrical energy. The temperature of hot water produced by ordinary heat pump water heaters can generally only reach 50-60°C, which cannot meet the requirements of high-temperature hot water in some places. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art, and provide an air source heat pump water heater unit with high efficiency, ene...
