Description
Technical field
The present invention is the accumulation energy type heat pump assembly of a kind of solar energy and air combined thermal source, relates to the technical field that solar energy utilization and heat pump are made.
Background technology
Heat pump has higher efficient and special advantages at the heat such as the aspects such as domestic hot-water, building heat supplying and low temperature drying that obtain low taste, more and more widely be applied to industry and field such as civilian.Utilization as the high-grade energy solar energy of shortcut is the emphasis that scientist pays close attention to always, obtains the concern of national governments now again because of energy shortage.With solar energy and heat pump in conjunction with the heat that low taste is provided, as hot water and building heat supplying and drying etc., consumption that can saves energy, the burning of fossil fuel, not only energy savings but also protect environment was a kind of good power save mode.
Aspect domestic hot-water supply, at present, the most of families of China have used gas heater, electric heater or solar water heater, gas heater and electric heater all are by the fuel combustion of GOOD TASTE and use the electric energy of GOOD TASTE to obtain the low bathing of sampling hot water (generally about 50 ℃).This is the very inefficient utilization to the energy, to the big country of the such conventional energy resource deficiency of China, is a kind of waste to the energy, and is opposing with the international and domestic energy saving policy of advocating energetically, and the corresponding also increase of use cost; Solar water heater utilizes solar radiant energy that hot water is provided, be a kind of China and global energy development plan of meeting, the good product of energy savings, obtain use more and more widely in town and country, but weak (winter, overcast and rainy in order to overcome solar radiation, evening) the not enough disadvantage of hot water temperature the time, general employing Electric heating, and electrical heating remains a kind of poor efficiency, expensive mode of heating.
And present existing Teat pump boiler mostly utilizes air as the environment thermal source, the low taste of absorption heat energy is warmed up to about 50 ℃ by the work of heat pump from air, Teat pump boiler has the efficiency of energy utilization apparently higher than electric heater, but Teat pump boiler when the solar radiation in summer is very strong still consumed power obtain hot water, can not utilize solar radiant energy, when air temperature was low in the winter time, the efficient of heat pump obviously reduced, and outdoor evaporimeter can't be worked because of frosting.
The solar heat-pump water heater of general direct expansion utilizes solar radiant energy as thermal source, reached and both utilized solar radiant energy, utilize heat pump to produce the high efficiency advantage of low-temperature water heating again, but common solar heat-pump water heater is not having under the situation of solar radiation, be subjected to the restriction of conventional collector structure, heat pump is difficult to absorb heat from air, causes common solar heat-pump water heater operating efficiency in this case still not high.
Aspect the heat supply of building, air-cooled and water resource heat pump is used widely, similar Teat pump boiler, and air-cooled heat pump need be taked electrical heating or other auxiliary heat supplying mode owing to obtain the efficient reduction of the heat pump of heat in the winter time from air; The cold and hot pump chamber external heat exchanger of dry monsoon frosting problem is the field of Refrigeration and Air-conditioning outstanding question always, influences the operation of heat pump; Water resource heat pump has the example of using in conjunction with underground water, but be subjected to the restriction of a lot of conditions, use seldom, the water-cooled unit adopts the mode of heat supply combinations such as water-cooled handpiece Water Chilling Units other equipment of cooling such as oil oven, the research of earth source heat pump is in conceptual phase, be not widely used by condition restriction.And solar radiant energy as a kind of energy of very easy acquisition not by in the middle of the very effective heating that is applied to building, main because solar radiation can be the energy of discontinuity, need effectively to solve the energy storage problem.
