Definitions

  • the invention relates to a system for carrying out a heat pump process for heating purposes, in particular for heating or cooling building interiors, which system is an expander which is operated by the vapor of a refrigerant brought to elevated pressure and temperature, and a heat pump compressor coupled directly to the expander includes.
  • the principle of operation of this system is essentially based on a combined Rankine / Lorenz heat pump process, in which a halogenated hydrocarbon-based refrigerant can be used to operate the expander and any energy source can be used to heat the boiler system.
  • a better use of the energy content of the energy source used is brought about by the diesel or gas piston engine as the driving machine, in particular if the waste heat contained in the combustion gases is also used.
  • a major disadvantage of such an arrangement is the noise and vibration tendency inherent in an internal combustion engine, and the need for maintenance, such as e.g. Oil change, etc .; in addition, there is a commitment to a liquid fuel.
  • DE-OS 2 751 003 describes a heat pump system with an air source and a rotary piston compressor and expander with several slide valves, which can be used for area heating of a building to be air-conditioned.
  • This known system is a complicated system with a large number of units, including a special control device for the refrigerant flow, but the thermal link is limited to the actual heat pump system and neither the use of residual flue gas heat nor the use of the heat content, which significantly improves the overall efficiency of heating return water is provided.
  • the invention is based on such a system that an expander operated with refrigerant vapor and one directly with it coupled heat pump compressor comprises.
  • this system is now characterized by a refrigerant evaporator heated by means of a liquid, gaseous or solid energy source or by means of thermal energy from radioactive decay processes for evaporating the refrigerant conducted in a closed circuit, by a low-noise and low-vibration screw expander, which drives a compressor heat pump serves, through a condenser acted upon by heating return water for the condensation of the refrigerant vapor coming from the screw expander as well as through a collecting container for the liquid refrigerant together with the return line to the evaporator and boiler feed pump.
  • a particular advantage of the system according to the invention lies in the special thermal connection of the energy flows here, which are supplied by the flue gas or another carrier of thermal energy, by the outside air used as heat carrier and by the heating water supply and return, and which this system, make it technically and economically usable, especially in the power range from 5 to 40 kW already mentioned.
  • the refrigerant evaporator preferably a once-through boiler
  • a downstream heater for the reheating of the heating water which is connected to the flue gases or the heat transfer medium in the case of radioactive decay processes, and forms a unit with it.
  • This combination of refrigerant evaporator, downstream heat recovery boiler for reheating the heating water whereby there is also the possibility of a pure heating operation with the refrigerant evaporator switched off, provides an economical and particularly low-noise and low-vibration provision of low heat (5 to 40 kW).
  • the reheater can advantageously be arranged and dimensioned in such a way that heating operation is also possible if the heat pump fails.
  • the system according to the invention is advantageously designed in such a way that the condenser for the refrigerant vapor emerging from the screw expander with the heating water circuit for releasing part of the heat content of the heating return water for heating the useful heat transfer medium supplied to the heat pump circuit, e.g. Air, is connected.
  • the heat pump circuit e.g. Air
  • This embodiment of the system has the advantage that part of the heating return water for preheating and de-icing the air / heat exchanger of the heat pump is used or prevents the exchange surface from freezing, which also enables improved condensation heat dissipation and improves the coefficient of performance by reducing the temperature spread becomes.
  • the heat pump itself is operated and controlled in a known manner.
  • the system according to the invention which comprises an expander-operated, encapsulated heat pump in a low-vibration and low-noise design, combines the important advantages that. Iie waste heat is largely exploited and that all liquid and gaseous energy sources can be used directly or indirectly to operate the system, the changeover can be carried out in a simple manner by exchanging or adapting the burner. Heating using solid energy sources, such as coal in half-gas or fluidized bed combustion systems, is also technically easy to carry out. The decay heat of radioisotopes can also be used advantageously as a heat source.
  • a microcomputer control system can be used for the operation of the heat pump according to the invention, which makes it possible to automatically control the individual functions of the system elements, depending on the outside temperature or heat demand on the heating circuit.
  • the system can be designed for a range of heating power from 3 to 200 kW.
  • a heat output of 5 to 40 kW is preferred.
  • the described design of refrigerant evaporator, reheater for the heating water and the possibility of operating it without switching on the refrigerant circuit ensures optimal and safe provision of heating energy and at the same time achieves a very compact unit that - assembled together - can be set up like a boiler.
  • Example: For heating a single-family house is a heat pump system of the type according to the invention, which has a heating output of -10 ° C at an outside temperature 24 kW, in the manner shown in the attached drawing:
  • the refrigerant vapor entering a condenser 2 of the refrigerant circuit is condensed there by means of heating return water 7, which has a temperature of about 30 ° C., and returned to a container 3 with level control, about 9.5 kW being given off to the heating water.
  • the refrigerant is recirculated from the container 3 via the pump 4 and the valve 5 to the evaporator 12, where it is liquid, e.g. at 40 ° C / 26 bar.
  • the heating return water 7 heated in the condenser 2, for example to 41 ° C., is fed to the condenser 11 of a conventionally operating compressor heat pump 8 - 11, the compressor 8 of which is directly coupled to the screw expander 1 and operates at 3000 rpm, and there at approximately 56 ° 0 warmed.
  • the circulating heat transfer medium after exiting the condenser 11, passes through a throttle 10 into the heat pump evaporator 9, in which the medium, e.g.
  • the heating water coming from the condenser 11, preheated to 56 ° C, is now fed to a downstream heating water reheater 13, where it absorbs a further 2.5 kW of useful heat and then supplies the heating system of the house with a flow temperature of 60 ° C as the heating water flow 20.
  • the reheater 13 for the heating water like the evaporator 12 for the refrigerant, is installed in a boiler arrangement 14, which thus comprises both the refrigerant circuit and the heating water circuit.
  • the boiler arrangement is operated by means of a burner / or.
  • the required thermal energy is supplied by means of a half-gas or fluidized-bed combustion and released to the two aforementioned circulation systems via the flue gas.
  • a control cap 15, which is intended for regulating the heating water temperature, is advantageously installed in the boiler arrangement 14.
  • the control flap is controlled depending on the heating water outlet temperature.
  • the heating water reheater 13 is operated alone, which, for example, enables the heating to continue to be operated in the event of a fault restricted to the refrigerant circuit.
  • This operation of the downstream heating water reheater as the sole heating unit can be brought about by a corresponding design of the control flap as a flue gas deflection device.
  • the flue gas deflecting device can also be designed in such a way that the heating surface of the heating water reheater 13 is bypassed, which is important in the event that it can be found that the heating water has a lower supply temperature.
  • the heating return water 7 is passed through an upstream air heater 6, which prevents icing of the air / heat exchange of the air / heat exchanger of the heat pump evaporator.
  • An additionally provided bypass line 16 with a switching valve 17 enables the heating return water 7 to be fed directly to the condenser 2 of the screw expander 1 at higher outside temperatures.
