Definitions

  • the invention relates to a device for obtaining heat according to the heat pump principle from surrounding heat sources, such as outside air, solar radiation, etc., domestic waste water and from the waste heat of a heat pump drive internal combustion engine.
  • German patent applications P 26 34 233.6-13 and P 27 15 075.0 describe heat pump systems for the generation of heat from surrounding heat sources, which work with a water storage tank which on the one hand works with the surrounding heat sources and on the other hand uses an evaporator to exchange heat with the refrigerant circuit of the heat pump stands. Due to the removal of heat from the water reservoir into the refrigerant circuit, this water reservoir is constantly at a very low temperature level, in general 0oC, so that in winter almost always, except in Frost periods, a heat transfer from the warmer heat sources into the water reservoir is possible. Since the amount of heat transferred via the refrigerant circuit into a heating circuit is extracted essentially exclusively from the water reservoir, a relatively large water reservoir is required for heating a family home.
  • a reduction in the size of the water reservoir is possible if, according to the teaching of "Oil + gas combustion 12/1976" page 676, a diesel engine is used as the heat pump drive, the exhaust gas heat and cooling water heat of which are at least partially transferred to the heating circuit, and the amount of heat no longer produced by the heat pump need to be applied.
  • the heat pump system according to US Pat. No. 3,563,304 uses two refrigerant evaporators, the first of which is in heat exchange with the surrounding air and the second with a water reservoir.
  • the main heat is supplied via the first evaporator as long as the ambient temperature is significantly above 0 ° C.
  • the heat required is extracted from the water reservoir by ice formation by the second evaporator.
  • the ice melts back at times of cheap night-time electricity using electrical resistance heating.
  • a disadvantage is the relatively high power consumption due to the electrical resistance heating, which has to be switched on very frequently, since even at outside temperatures of around 5 - 8 ° C the outside air evaporator can no longer bring in the amount of heat required for heating due to icing.
  • the invention has for its object to provide a device for obtaining heat according to the heat pump principle from surrounding heat sources, which manages with a relatively small water storage.
  • the device to be created should also do without additional electrical heating and work in an environmentally friendly manner.
  • a device of the type mentioned at the outset which is characterized according to the invention by a refrigerant circuit with a first evaporator which is in heat exchange with the outside air and with a downstream second evaporator which is in heat exchange with a water store, which water store in turn with heat sources, such as solar radiation, house wastewater, is in heat exchange and contains a refrigerant condenser that can be switched on temporarily in the refrigerant circuit in warm weather.
  • the first evaporator which uses the outside air heat, is arranged in the refrigerant circuit immediately behind the expansion valve. In cold weather and / or largely no wind, less refrigerant will evaporate in it than in warm and / or very windy weather. The part of the refrigerant which is still liquid after passing through the outside air evaporator is evaporated during the subsequent passage through the refrigerant line located in the water or latent heat store.
  • the outside air heat that is available after the respective weather is used to evaporate the refrigerant. If this is not sufficient for this, the respective residual liquid is evaporated by taking energy from the latent storage.
  • the size of the outside air evaporator and the latent heat store are to be coordinated with one another in an economically optimal manner, taking into account that there is not always space for the installation of a larger storage tank. It should also be taken into account in such considerations that it can be cold for a long time and then after the storage basin has iced up, it is no longer possible to extract enough heat of vaporization.
  • This problem can be solved without having to oversize the outside air evaporator by assigning one or more blowers to the outside air evaporator, which are under the control of an outside air temperature sensor and possibly an anemometer.
  • This outside air temperature sensor only starts the blower (s) below an adjustable outside air temperature, eg -10 ° C, in order to ensure a minimum air speed that can be determined by the blower.
  • the latent heat storage can also be kept smaller.
  • the switchable blower can be designed for a certain constant minimum air speed or can have a speed controller under the control of the outside air temperature sensor in order to increase the blower speed with falling outside air temperature.
  • the heat supply of the latent heat storage is used during unfavorable weather conditions, if necessary up to the partial icing of the water content.
  • the outside air evaporator can be used in periods of warm weather, for example from an outside temperature of + 10oC can be used to regenerate the energy supply in the latent heat storage. In such warm weather, engine waste heat and the heat of the exhaust gases are sufficient to heat the house.
  • the heat pump process is then used by means of temperature-controlled automatic switching in order to bring outside air heat into the latent heat store with high efficiency via an additional condenser located in the latent heat store.
  • the refrigerant circuit of the device for the production of heating heat consists of a compressor 1, a condenser 3 which is in heat exchange with the heating circuit 2, an expansion valve 4 and a refrigerant evaporator 6 immersed in a water reservoir 5.
  • the refrigerant evaporator 6 immersed in the water reservoir is preceded by an outside air evaporator 7 which, depending on the external weather, evaporates a more or less large part of the refrigerant and thus relieves the water reservoir 5.
  • the outside air evaporator 7 has the further task of increasingly transferring outside air heat into the water storage device in relatively warm weather to regenerate the water storage device.
  • a two-way solenoid valve 8 is switched on in the refrigerant circuit immediately after the compressor 1, which in suitably warm weather does not direct the refrigerant vapor coming from the compressor into the condenser 3 of the heating circuit 2, but into the condenser or condenser immersed in the water reservoir 9.
  • the outside air heat absorbed by the outside air evaporator 7 and the compression work of the compressor converted into heat then serves exclusively to heat the water reservoir, while the heating circuit 2 is heated by the waste heat of the provided for driving the compressor 1 diesel engine 10.
  • the cooling water circuit 11 and, on the other hand, the exhaust line 12 of the diesel engine are exchanged with branches of the return line of the heating circuit 2 connected in parallel.
  • the outside air evaporator 7 advantageously has a battery of parallel evaporator tubes, which are arranged at an oblique angle in the heat of a house. To ensure a minimum amount of air passing through the evaporator 7 in cold and calm weather, the evaporator is assigned fans 16, which are under the control of an outside air temperature sensor 17, which starts the fan when the temperature falls below an adjustable outside air temperature. The heat supply in the water reservoir 5 to replace the heat extracted by the evaporator 6 takes place in the case shown

Abstract

L'installation comprenant une pompe a chaleur est utilisee pour recuperer de la chaleur pour le chauffage a partir de sources de chaleur environnantes, telles que l'air exterieur, est munie d'un reservoir a eau (5) qui est en relation d'echange de chaleur, d'une part avec la source de chaleur environnante et, d'autre part, avec le circuit de refrigerant de la pompe a chaleur a travers un evaporateur de refrigerant (6). En prelevant de la chaleur du reservoir d'eau (5) et en l'introduisant dans le circuit du refrigerant on obtient que le reservoir d'eau (5) se trouve toujours a une temperature basse approchant 0 C de facon qu'il y ait presque toujours un transport de chaleur des sources environnantes vers le reservoir d'eau (5). Pour pouvoir reduire les dimensions du reservoir d'eau (5) on prevoit un evaporateur de refrigerant (7) qui est en contact avec l'air exterieur et qui evapore une partie du refrigerant qui est variable selon la temperature exterieure. Dans des periodes chaudes l'evaporateur exterieur (7) peut etre utilise pour rechauffer le reservoir d'eau (5) eventuellement gele en introduisant dans celui-ci la chaleur provenant de l'air exterieur a travers un liquefacteur additionnel (9) situe dans le reservoir d'eau (5).
