Air source heat pump unit with variable air rate and split chamber temperature control function

Abstract

The invention relates to an air source heat pump unit with the variable air rate and the split chamber temperature control function. The air source heat pump unit comprises an air source heat pump water heating unit, a heat preservation water tank and a plurality of cooling fins; the air source heat pump water heating unit comprises a compressor, a water side heat exchanger, a throttle valve and an outdoor heat exchanger which sequentially communicate through a heat medium pipe in a circulated manner; the heat preservation water tank is composed of a water supply zone at the upper portion anda water return zone at the lower portion, and the middles of the water supply zone and the water return zone communicate with each other; and the water return zone communicates with the water side heat exchanger, the water supply zone and the cooling fins through a water pipe in sequence in a circulated manner. According to the air source heat pump unit, the draught fan running quantity and rotating speed are adjusted to achieve adaptive regulation of the working power of an evaporator, economical, efficienct, energy-saving and environmnet-friendly indoor heat supply is facilitated, meanwhile,damage to the compressor is reduced, and the overall service life of the unit is better improved; and independent temperature control valves arranged on the multiple cooling fins can adjust water flow in the cooling fins according to the temperature needs of different rooms, difference control can be achieved on the room temperature, and meanwhile, the energy conservation and economical benefitsof the unit are improved.

Description

technical field [0001] The invention relates to the field of heat pump hot water units, in particular to an air source heat pump unit with the functions of variable air volume and compartmental temperature control. Background technique [0002] In recent years, due to the shortage of power resources and the enhancement of residents' awareness of environmental protection, heat pump hot water units have developed rapidly due to their advantages of energy saving and environmental protection, and air source heat pumps, which use the atmosphere as a low-temperature heat source, are favored by the society because of their excellent operability. In the prior art, the area of ​​the evaporator in the air source heat pump unit is fixed, but the atmospheric temperature varies greatly throughout the year, which causes the evaporation temperature and pressure to be low when the atmospheric temperature is low in winter, and the condensing temperature and pressure to be high in summer. It ...

[0002] In recent years, due to the shortage of power resources and the enhancement of residents' awareness of environmental protection, heat pump hot water units have developed rapidly due to their advantages of energy saving and environmental protection, and air source heat pumps, which use the atmosphere as a low-temperature heat source, are favored by the society because of their excellent operability. In the prior art, the area of ​​the evaporator in the air source heat pump unit is fixed, but the atmospheric temperature varies greatly throughout the year, which causes the evaporation temperature and pressure to be low when the atmospheric temperature is low in winter, and the condensing temperature and pressure to be high in summer. It is impossible to adjust the working power of the evaporator according to the external atmospheric temperature, which will cause damage to the compressor
