Description
Technical field
The present invention relates to a kind of air source hot pump water heater high pressure-temperature discharging methods.
Background technique
With the continuous improvement of living standards, demand of the people to hot water increasingly increases, the requirement to temperature pleasant hot water
Also higher and higher, either temperature is low or temperature is high, and hot water becomes the demand comfortably lived.
Currently, air source hot pump water heater is under summer high-temperature environment, mainly using the low wind of the high wind of outdoor fan convert come
The running pressure of compressor is unloaded, but precision is not high, optimum state is not achieved in heating capacity and COP value.Because high wind and
Low wind switch condition only judges water tank temperature and environment temperature, and these temperature values be it is fixed, can not be according to oneself operation
It actually corrects, these parameters fixed will lead to partial air source heat pump water heater and unload in advance, and heating capacity, energy-saving effect are not
It is good, the lag unloading of partial air source heat pump water heater is also resulted in, unit generates high voltage protective under high temperature environment；In addition to this,
It also cannot be considered in terms of exhaust according to this two conditions, Domestic Air Source Heat Pump Water Heater runs delivery temperature under high temperature environment and also can
Very high, serious person will lead to compressor lubricant oil carbonization, and unit is scrapped.
When household air source heat pump hot water system is run at a high ambient temperature, compressor is because of evaporating pressure height, operation pressure
Power is also with rising, if pressure and delivery temperature are not unloaded well, it is excessively high and produce to will lead to compressor pressure
Raw high voltage protective, especially when high water temperature；Unit how is allowed to be run smoothly at a high ambient temperature without generating high pressure
Protection, accurate unloading pressure, how to allow unit quantity of heat production and pressure to reach an optimum state becomes what industry was studied jointly
Project.
