Heating system using a heat pump

The present invention relates to a heating system using a heat pump with direct introduction of the primary medium into the radiators.

The purpose of the invention is to create a system of the described above, but in which no intermediate medium is used, as is usually the case in conventional heat exchangers; that's how you get one considerably higher efficiency and thus a corresponding energy saving.

The invention provides a combination of the following elements: an air evaporator unit or unit in which the heat exchange medium (e.g. Freon or similar) changes from the liquid to the gaseous state, and in connection with it ο «standing, a number of Heizkörporel cnicnl cn in the to be heated Came in which the evaporator from the crane] age Incoming steam condenses and gives off heat to the environment.

The mentioned radiators consist of a number of parallel, interconnected pipe coils in a corresponding housing Shape and dimensions; A large number of metal wires are welded onto these pipe coils, so that a lattice with a noticeable heat exchange capacity

There now follows a description of the invention with reference to the accompanying figures; these drawings are intended to illustrate how the practical - not necessarily yet final - embodiment of the invention itself should preferably look.

Explanations of the figures:

In Fig. 1, the number 1 indicates the overall complex of the evaporator unit in which a heat exchange medium, e.g. Freon, evaporates and through a feed line 2 to a Row of radiators 3 is directed; here the ™ condensation of the steam coming from the unit 1 takes place Release of heat to the environment. After condensation, the condensate is through the return line 4 to Evaporator unit 1 returned.

From the previous statements it appears that the basic feature of the invention is that for the the working medium is used throughout the thermal cycle without the use of an intermediate medium (water),

The radiator 3 (Fig. 2) consists of a housing 5, in which two or more pipe coils.6 with intervening Radiation grids 7, consisting of metal wire, are mounted. The pipe coils 6 are at their ends summarized by collectors 8, which lead to the supply line or return line 4. The radiator 3 can be static Radiators, or be designed as a fan heater.

The evaporator unit 1 can be placed anywhere inside or outside the house, e.g. on a balcony, be accommodated; it can be suspended (see Fig. 4) or installed at floor level (see Fig. 5). That Evaporator unit 1 (FIGS. 1 and 3) is mounted in a closed housing 9; the outside air is via the Floor grille 10 with the help of the fan 11 through the evaporator block 13 and exits at the upper grilles 12.

The vaporous medium coming from the motor compressor 14 is passed through the supply line 2 to the radiators 3 ^ου ; there, as already mentioned, condensation takes place and the medium flows back through the pipeline. Before it reaches the evaporator 13, it flows through the dry filter 15, the valve 16 and the capillary 17, which opens into the pipeline 26. At the outlet of the evaporator 13, a pipe 18 is connected through which the steam is passed to the liquid tyabsclu'idor 19; from this the steam passes through the pipe 20 to the compressor 14, and the circuit is thus

• 1 .sch! nozzles.

The electrical control panel 21, which is not described in detail here is, coordinates and controls all functions,. • 5 such as dmi room thermostat 22, the evaporator defrosting • control .23, the heating resistor 24 in the liquid separator 19.

The "heating resistor 24 has the task of being controlled by the Defrosting device 23, an additional heat source in the Bring liquid separator 19 and thereby support the defrosting process. In addition, you can achieve this the evaporation of the liquid contained in the separator 19 with the advantage that an additional amount of gas in the Cycle arrives.

The abbot c »u :: l curl uiuj 2Λ bowitkt not only the heating of the resistor 24, but also acts on the electrically controlled valve 25, which leads the gas coming from the motor compressor 14 directly via the line 26 into the evaporator and thus shortens the cycle. After defrosting has taken place, the electrically controlled valve 25 blocks the passage and the gas is fed into the supply line 2 again.

The description of the present invention illustrates the preferred mode of implementation, possibly of Changes can be made by a specialist can, however, without going beyond the scope of the present

^ou go beyond patent protection.
