Technical field
The utility model relates to cooling supply heating technology field, in particular to a kind of super cumulative heat pump solar energy cold-heating system.
Background technique
Rural areas in our country mostly uses greatly the modes heating such as coal-fired or biomass at present, as the popularization that coal changes electric policy is real
It applies, the heating of rural subscribers becomes urgent problem to be solved.Solar energy is obtained as clean renewable energy in every field
It is widely applied, the application in terms of heating is also one of the emphasis studied at present.But utilize solar heating by day
Gas and seasonal effect are very big, because mostly using solar energy+supplementary energy united heat mode in the industry.
China's cold district winter temperature is lower, and dry.Outdoor design temperature for heating substantially at -5 to -35 DEG C,
Most cold monthly average outside relative humidity is substantially between 45%-65%.Air source heat pump, frost are selected in these areas
It is less serious.Therefore it says, frosting problem is not the biggest obstacle of these regional use in winter air source heat pumps.But there are following
Some restriction air source heat pumps are the problem of cold district is applied: (1) when the heat ratio of needs larger when, air source heat pump
Heating capacity it is insufficient；(2) poor reliability that air source heat pump is applied in cold district；(3) at low ambient temperatures, air source heat pump
