Description

A kind of solar air source heat pumps
Technical field
The utility model relates to and heats refrigeration technology field, is specifically related to a kind of solar air sourceHeat pump.
Background technology
Along with the anxiety of the energy and the enhancing of environmental protection consciousness, the exploitation of regenerative resource and profitWith receiving much concern, and solar energy is a kind of safe, clean regenerative resource, widely applicationIn hot water preparing. But the use of solar energy is subject to the impact of Changes in weather larger, has unstableProperty, traditional solar energy hot device cannot utilize solar radiation at night, or in solar radiationIn weak situation, because the solar thermal collector in apparatus for heating water by solar energy leaks heat, solar energyThe temperature of heating combined equipment hot water preparing cannot reach user's demand.
Air source heat pump uses heat pump operation principle, utilizes airborne low grade heat energy to produce heightWarm water, has and can use throughout the year, is not subject to the advantage of influenced by solar. But traditional skyThe performance of air supply heat pump is subject to the impact of evaporating temperature, and in the situation that environment temperature is low, efficiency is lower.And in actual application, there is the problem of frosting, particularly and humidity on the low side in temperature is veryLarge area, the frosting of outdoor air cooling heat exchanger manifests particularly serious. Existing defrosting scheme hasCold-producing medium inverse defrosting, thermal storage defrosting and waste heat defrost three kinds, cold-producing medium inverse defrosting and accumulation of heatDefrosting can affect the heating effect of user's side in the process of defrosting, although waste heat defrosting can shadowRing the heating effect of user's side, but can make the service efficiency of the primary energy of air source heat pump decline,Do not reach the object of energy-conserving and environment-protective.
Existing a kind of solar air source heat pumps, by air source heat pump and the organic knot of solar radiationClose, utilize solar thermal collector hot water preparing, in the time that solar radiation is sufficient, can directly utilize the sunRadiation heats, and in the time that solar radiation is not enough, utilizes air source heat pump to heat, and solves solar radiation notStable problem, but weak solar radiation do not utilized. Therefore, air source heat pump existsThe frosting problem that temperature is on the low side, humidity exists when larger is resolved not yet.
Existing another kind of solar air source heat pumps, makes up too utilizing air source heat pump to heatWhen the unsettled defect of sun radiation, utilize solar radiation for air source heat pump defrosting, defrost formerReason is: in environment temperature during higher than 0 DEG C, and the direct hot water preparing of solar thermal collector, and environment temperatureWhile spending lower than 0 DEG C, solar thermal collector being connected with air source heat pump evaporator, is air-source heatPump defrosting. But this method has been ignored the shadow of solar radiation radiation to solar thermal collector heating capacityRing, in the time not needing to defrost, do not utilize weak solar radiation, therefore, a little less than solar radiationOr while thering is no solar radiation, solar thermal collector cannot be air source heat pump defrosting.
Existing another kind of solar air source heat pumps has increased again produces solar thermal collectorHot water is as the branch road of source heat pump heat, to utilize weak solar radiation to remove for air source heat pumpFrost. But this solar air source heat pumps is still and utilizes solar radiation for air source heat pump defrosting,And solar radiation has unstability, cannot ensure reliability and the defrosting of air source heat pump defrostingEffect.
And existing solar air source heat pumps adopts heat exchanger to realize solar radiation directly to makeHeat, thereby water pump, pipeline etc. that need to be supporting with heat exchanger, cause solar air source heat pumpsComparatively complicated.
