Solenergi varmepumpesystemer funksjon-nytt-345

The solar energy heat utilization technology and the heat pump technology’s union is flexible, the system form are also many and varied, generally may divide into the solar energy actuation heat pump and the solar energy auxiliary varmepumpe two broad headings. The solar energy actuation heat pump is mainly refers to the solar energy electro-optic or the thermoelectricity actuation compression type varmepumpe as well as by the solar energy radiating heat direct drive absorption type, the adsorption type, the jet type and chemistry heat pump and so on. This kind of heat pump mostly take realizes the solar energy refrigeration air conditioning as the main purpose, generally is high to the solar energy collection hot temperature request, and has the volume to be big generally, the cost is high, the efficiency low status question, difficult to realize the miniaturization and the commercialization development. The solar energy auxiliary heat pump usually is refers to takes the solar energy heat utilization system auxiliary unit the heat pump system, including is independently auxiliary the heat pump and takes the evaporator heat source by the solar radiation heat energy the heat pump. This kind of heat pump most heats primarily, involves the construction to heat, life application domains and so on hot water supply as well as industrial used heat, is not high to the solar energy collection hot temperature request, and has the nimble diverse system form, the reasonable economical technical performance and the good commercial practical application prospect. According to the collection hot medium’s difference, the solar energy auxiliary heat pump may divide into generally swollens the type straight and non-swollens the type two broad headings straight. Swollens in straight the type system system, the refrigerant takes the solar energy collection hot medium the heat absorption to evaporate directly in the solar energy collection heat/evaporator, then for is heated up through the heat pump cycle the heat of condensation release the object. This kind of system has miniaturized and the commercialization development potential extremely, but because the solar energy radiation condition the geographic latitude, the season is transformed, the day and nights change and each kind of complex climatic factor influence momentarily is in the change, but the operating mode unstable will certainly to cause the system performance the fluctuation. Non-swollens in straight the type system, the solar energy collection hot medium usually picks fluids and so on water used, air or antifreezing solution, causes them to absorb the quantity of heat in the solar energy collector, then transmits directly this quantity of heat for the heating object or elevates temperature after the heat pump cycle heats up again as the evaporator heat source the object. According to the solar energy collection hot circulation and heat pump cycle’s different connection type, non-swollens the type solar energy auxiliary heat pump to be possible straight to divide into tandem, the parallel and the double heat source type three fundamental modes. The tandem type is refers to the solar energy collection hot circulation and the heat pump cycle connects through the evaporator, the evaporator heat source comes from the quantity of heat which completely the collection hot circulation absorbs; The parallel is refers to the solar energy collection hot circulation and varmepumpe cycle each other is independent, the latter only takes the former cannot meet when the heating need the auxiliary heat source; Double heat source type and tandem type basic same, was only in the heat pump cycle has included two evaporators, might simultaneously use including the solar energy two kind of low temperature heat sources or the two mutually is the supplement. Because the double heat source type solar energy auxiliary heat pump uses including the solar energy two kind of low temperature heat sources or the two is the supplement mutually, enables the system to have a better stability. Moreover, may increase the regeneration installment in the system, reduces the heat pump unit rated capacity, to reduce the system operating cost, enhances the solar energy interdependence rate (to define to come from the sun to be much more effective occupies needs heat load proportion), and the summer may also carry on the accumulation of cold movement which has nothing to do with the solar energy meets the room air conditioning’s need.
Because the solar radiation has the discontinuity, the undulatory property in a big way and so on shortcomings, but intensity of solar radiation’s change will certainly to cause the heat pump system performance the fluctuation. Therefore, how both can use the solar energy and to be able fully guarantee system’s stability, is the solar energy varmepumpe system moves toward the important question which the practical application must solve. At the same time, the commercial fission air conditioning and the home use electric boiler’s widespread application, makes the family electrical energy the consumption to increase large scale. Therefore, may consider that the solar energy heat pump and the hot water supply union movement, uses in substituting the fission air conditioning and the electric boiler. From this, may use the solar energy, satisfies the user air conditioning and the life hot water request, reduces the user to consume the electricity expense.
