Definitions

  • the invention relates to a method for heating buildings using at least one absorption heat pump, with which heat from the environment can be absorbed, in which method when an ambient temperature exceeds a certain transition value in a first mode of operation continuously evaporates an operating medium at low pressure in an evaporator and removes heat from the environment, the evaporated operating medium is absorbed by an absorption liquid located in an absorption vessel, from this absorption vessel continuously absorbs absorption liquid with the operating medium absorbed therein by a pump into a boiling vessel and is heated therein, whereby operating medium is driven out of the absorption liquid, the expelled Operating medium at higher pressure with the release of heat condensed by the condensing operating medium in a condenser, which heat directly or via one or more heat exchangers to e a room to be heated or several rooms to be heated is transferred, the condensed operating medium is fed back to the evaporator via a throttle valve and the absorption fluid, which is low in operating medium, flows back to the absorption vessel via a further throttle valve, and by which
  • the cold heat source called 'environment' can be outside air, but also e.g. open water, groundwater, soil, industrial water, etc. Heating processes based on heat pumps offer good prospects for saving primary energy, especially for space heating.
  • part of the liquid operating medium condensed in the condenser, bypassing the evaporator is fed to the absorption vessel in order to obtain a sufficient circulating amount of operating medium.
  • the circulation of the absorption liquid must be maintained. If almost the entire circulating amount of operating medium bypasses the evaporator, there can hardly be any question of heat pump action and the circulation of the absorption liquid means an almost useless and uneconomical load on the system.
  • the object of the invention is to improve the economy of such a heating method.
  • this improvement is achieved in that the absorption liquid is stored in the second mode of action, the connections between the condenser and evaporator, absorption vessel and pump, and boiling vessel and absorption vessel are blocked, the condenser drain is connected to the pump, and condensed operating medium is pumped to the boiling vessel, which The operating medium is then evaporated in a circulation system in the boiling vessel and condensed in the condenser, with heat being transported from the heated boiling vessel to the condenser. Water is preferred as the absorption liquid and ammonia is preferred as the operating medium.
  • the absorption liquid is preferably stored in the absorption vessel.
  • the method according to the invention When the method according to the invention is used in the first mode of action, ice can be deposited on the evaporator, the pressure in the evaporator decreasing.
  • the method according to the invention is then preferably carried out such that the method is carried out temporarily in the second mode of action at an ambient temperature above the selected transition value in the event of a pressure reduction in the evaporator due to ice deposition on the evaporator, the absorption liquid stored in the absorption vessel also evaporating and in the evaporator below Heat condenses, causing the ice deposited on the evaporator to melt, and that if the pressure in the evaporator rises due to the disappearance of the ice deposit, the process of the first mode of action is carried out again.
  • the invention also relates to a heating system to carry out the method according to the invention with a circulation system in which an evaporator, an absorption vessel, a liquid pump, a boiling vessel to be heated, a condenser and a first throttle valve are arranged, and with a return line with a second throttle valve between the boiling vessel and the Absorption vessel, which together form an absorption heat pump with which heat can be absorbed from the environment in a first mode of operation of the system and can be transferred directly or via one or more heat exchangers to a room or several rooms to be heated and with a short-circuit line provided with a shut-off valve , with which, in a second mode of operation of the system, liquid operating medium condensed in the condenser can be conveyed at least partially bypassing the evaporator to a point in the circuit downstream of the evaporator.
  • the heating system according to the invention is characterized in that the short-circuiting line can connect the drain of the condenser to the supply of the liquid pump, the absorption vessel being so large that the entire supply of absorption liquid can be stored therein in the second mode of operation and shut-off valves are provided to prevent that To be able to shut off the evaporator and the part of the system formed from the absorption vessel from the rest of the system.
  • the drawing schematically represents a non-restrictive example of a heating system according to the invention.
  • the heating system shown works as follows: If the ambient temperature is not too low, the system is in the first operating mode and it functions as a heat pump. At the command of the control unit 33, the shut-off valves 4, 7, 17 and 20 are opened; the shut-off valve 23 is closed. The burner 10 is controlled by the gas shut-off valve 12 in such a way that the temperature measured by the temperature sensor 35 speaks the desired set value ", '1t.
  • Operating medium is evaporated in the evaporator 1, heat being removed from the surroundings. This operating medium is absorbed in the absorption vessel 2 by the The operating medium is expelled from the absorption liquid by heating in the boiling vessel 8. The vaporized absorption liquid is separated in the column 13.
  • the operating medium condenses in the condenser 14, gives off heat to the heat exchanger 24 and returns via the throttle valve 18 the evaporator 1.
  • the absorption liquid flows out of the absorption vessel 2 through the line 6, the pump 5, the line 9, the boiling vessel 8, the line 19 and the throttle valve 21 back into the absorption vessel 2.
  • water flows through the heat exchanger 24 and is heated in this exchanger.
  • the hot water is fed via the flue gas heat exchanger 39, which still absorbs heat from the combustion gases, and the line 25 into the heating radiators 26; the cooled water flows back through the return line 27 to the pump 32 and is then heated again in the heat exchangers 28, 29 and 24.
  • the amount of gas supplied to the gas burner 10 is set by the control device 33 in such a way that the temperature measured by the sensor 35 maintains a setpoint that has been set in advance. Possibly. a heat exchanger is also added so that the liquid in line 19 transfers part of its heat to the liquid in line 9, so that the latter is heated to some extent.
  • shut-off valve 4 Whether the shut-off valve 4 is open or closed in this second mode depends on the ambient temperature. If the ambient temperature is above the solidification point of the absorption liquid, not below 0 ° C or, for safety reasons, above 1-2 ° C. the shut-off valve 4 is opened; Absorption liquid evaporates in the absorption vessel 2, condenses in the evaporator 1 while releasing heat, so that ice deposited on the evaporator 1 melts and flows back into the vessel 2 as a liquid. The shut-off valve 4 is closed at ambient temperatures below 0 ° C.
  • the switchover from the second to the first mode of action takes place simply by opening the valves 4, 7, 17 and 20 and closing the shut-off valve 23 in the short-circuit line 22.
  • the system is operated in the second mode of operation as an evaporation-condensation system.
  • Hot water central heating is described in this example of a heating system according to the invention.
  • the heating system according to the invention can of course also be used in other ways, e.g. as a hot air heating system.
