The invention relates to heat engineering and can be used to produce thermal energy for heating of buildings and structures. Known heat pump installation including a pump with a heat exchanger placed in a tank filled with refrigerant and forming the evaporator, compressor and condenser connected through piping in a closed path,/E. I. Yantovsky, L. A. Levin, "Industrial heat pumps". Moscow, Energoatomizdat, 1989, page 120/.

In the known installation of the primary coolant, which you can use water or air, using a pump to a heat exchanger placed in a tank filled with refrigerant, and forming the evaporator.

The refrigerant takes heat from the heat exchanger evaporates and enters the compressor where it is compressed. However, in accordance with the Carnot cycle temperature Caliraya in the heating system.

A disadvantage of the known installation is a large expenditure of energy to compress the refrigerant in the compressor, which reduces the efficiency of heat pump installation. Thus, the lower the temperature of the refrigerant, the more you spend energy on compression.

The present invention is the task of creating such heat pump installation, the application of which would reduce the energy costs of compression, and thereby improve the efficiency of its work.

The problem is solved in that in the heat pump installation including a pump connected with the heat exchanger placed in a tank filled with refrigerant and forming the evaporator, compressor and condenser connected through piping in a closed circuit to circuit according to the invention, the installation further comprises a vortex chamber installed between the pump and the heat exchanger.

The low-temperature coolant /water or air/ by using a pump with a specific speed and pressure tangentially served in the vortex chamber, where it passes through the spiral, assuming the character of a vortex flow. Thus, in accordance with known laws of thermodynamics, the temperature rises, increasing the temperature is t for its compression in the compressor, the higher the efficiency of the boiler.

The invention is further illustrated by a detailed description of its implementation with reference to the drawing.

Heat pump system includes a pump 1 associated with the heat exchanger 2, is placed in a container 3 filled with refrigerant and forming an evaporator, a compressor 4 and a capacitor 5 connected through pipe 6 in a closed loop. Between the pump 1 and the coil 2 is installed swirl chamber 7. In the center of the end portion of the vortex chamber 7 has an outlet pipe 8, equipped with a diaphragm valve /drawing does not specify the/.

The operation of the device is as follows.

The primary coolant /water or air/ pump 1 at a certain speed and pressure tangentially served in the vortex chamber 7, where it passes through the spiral, assuming the character of a vortex flow. In the peripheral part of the vortex chamber, its temperature increases, and the axial part of the flow temperature is reduced. The resulting cold component of the flow through the outlet valve 8 is removed from the vortex chamber, and the hot component of the flow is fed to the heat exchanger 2. The temperature of the hot stream can adjust the capacity 3, forming together with the heat exchanger 2, the evaporator is heated to a temperature substantially greater than the temperature of the primary coolant /water or air/. And the higher the temperature of the refrigerant admitted into the compressor 4, the less energy it takes to compress. Then the refrigerant enters the heat exchanger of the condenser 5, which gives off heat network water circulating in the heating system, and the cooled refrigerant through the pipeline 6 re-enters the heat exchanger 2 of the evaporator, then the cycle repeats.

Heat pump system can operate in automatic mode, when the force of compression in the compressor 4, providing the desired heating temperature of the circulating water, significantly less than in the known heat setting adopted for the prototype.

The application of the inventive installation will significantly increase the efficiency of heating and to reduce the consumption of traditional forms of energy.

Installation is simple in manufacture and maintenance, can be made in the conditions of industrial production on standard equipment using standard components.

Heat pump installation can be used to create atny with heat exchanger, placed in a tank filled with refrigerant and forming the evaporator, compressor and condenser, and evaporator, compressor and condenser connected through piping in a closed loop, wherein the system includes a vortex chamber, the entrance of which is connected to the pump, and the output of the hot stream is connected to the heat exchanger.
