Description

A kind of single evaporator type solar air source combined heat-pump

Background technology

The whole world building heat supplying and domestic hot-water's energy consumption very large, the living standard that developed country is higher and habits and customs cause huge hot water demand and energy resource consumption, and developing country is then along with the development of urbanization and growth in the living standard can keep the rapid growth of energy consumption of hot water.The heating system that China commonly uses mainly adopts the mode of combustion of fossil fuel, and not only efficiency is low, and seriously polluted; Hot water supply system then mainly adopts gas heater and electric heater, there is the higher problem of wasting with energy grad of energy consumption.Heat supply and domestic hot-water more and more become energy-saving and emission-reduction, administer haze pay close attention to one of field.

In recent years, solar water heater and air source hot pump water heater obtain larger development.But there is the lower and unstable shortcoming of energy density in solar energy, when solar radiation is more weak, conventional solar boilers needs larger erection space to ensure heating capacity, when night without solar radiation time, solar water heater or heating system cannot heat, and usually need a set of backup electric heating system to ensure the reliability of heat supply.Therefore, traditional solar heat pump needs larger initial cost and higher operating cost, constrains its further large scale application.For air source hot pump water heater or heating system, because its heating efficiency and heating capacity all constantly can be decayed with the reduction of outside air temperature, also just reduce and heat reliability under its low temperature.Air source heat pump can only utilize the heat energy contained in air, effectively cannot utilize solar radiant energy, although and in fact winter, many times temperature was very low, intensity of solar radiation is still enough to produce required hot water.

In view of the problem that solar water heater cannot make full use of Low emissivity solar energy, air source heat pump cannot utilize solar radiant energy, the technical scheme that solar energy and heat pump techniques combine is obtained increasing favor.Wherein cold-producing medium directly passes in solar thermal collector by direct-expansion type system, can realize higher evaporating temperature, is conducive to reducing power consumption of compressor, is the system form that a kind of efficiency is higher.Current this kind of technical scheme is mainly divided into two classes: (1) only adopts a direct-expansion type solar energy heat collector as evaporator with heat pump, and namely solar energy is unique thermal source (as patent CN201110388936.2) of heat pump.Compared with conventional solar boilers, this type of scheme make use of more weak solar radiation to a certain extent more fully, but night still cannot heat without during solar radiation, also cannot utilize air heat energy, does not solve without heating problem during solar energy; And solar radiation more weak time, in order to meet the requirement of heating capacity, needing to adopt the larger solar thermal collector of area, making its cost higher; (2) adopt a direct-expansion type solar energy heat collector and a wind-cooled evaporator as evaporator with heat pump, time solar energy spoke is strong, solar energy directly heats, and runs air source heat pump pattern (as patent CN201120054202.6) under not having the sun or the more weak condition of radiation.This type of scheme can utilize solar energy, also air heat energy can be utilized, but heat pump needs employing two evaporimeters, its high cost, system complex, and such scheme can not realize directly heating of air heat energy and solar energy and combining of air heat energy heats.

It should be noted that, when the hot water temperature needed under certain situation is lower or outer temperature is very high (such as: during outer warm 30 DEG C of summer, produce the low-temperature water heating of 10 ~ 20 DEG C, for air heat energy across storing season), extraneous air heat energy also can directly heat, and all realized by air source heat pump at present, cause the energy consumption that heats higher.
