Description

The invention relates to the field of operation of heating systems.

A known method of operation of a warm pump (Kaganov MA "Thermoelectric pumps").

Earth and groundwater retain heat even in winter. Heat pumps can use this heat by raising the temperature of the heat removed and transferring it to the heating system.

In conventional domestic refrigerators, refrigerant circulates in a closed loop. It draws heat from the inside of the refrigerator and takes it out through the back wall. The heat pump works on the same principle, but it uses not cold, but heat. The heat pump removes the scattered heat with an anti-freezing fluid (antifreeze) from an external heat source (earth, groundwater, air). The temperature of this heat rises to the level required by the heating system. To increase the temperature, the heat pump needs extra energy. It has several circuits: external, internal and a circuit for transferring heat to the heating system. An effective heat pump is characterized in that the heat taken from an external heat source is many times higher than the amount of energy needed to raise the temperature.

The disadvantages of this system:

1. The consumption of electrical energy includes a secondary pump,

2. use of external territory (soil) or drilling a well.

The objective of the invention is to increase the efficiency of the system, eliminates the consumption of electrical energy from an external network, simplifying the heat pump circuit, freeing up the area occupied by the external circuit.

The problem is solved due to the fact that in the known method of operation of the heat pump system, a hydraulic ram is added.

A hydraulic ram is a hydraulic lifting machine that uses a hydraulic hammer to lift a liquid to a predetermined height (VM Hovsepyan “Hydraulic ram and ram installations”).

An indispensable condition for the operation of a ram is its location below the water level in the source, for example, below the water level in a reservoir, pond, river.

A hydraulic ram is a water lift in which the engine and pump are combined in one machine with a very simple design that works automatically.

A hydraulic ram can be performed not only for inclusion in a heat pump circuit, but it can be used to provide water for various objects, as well as for irrigation and irrigation of the adjacent agricultural territory.

To implement this method of work, it is proposed to change the known scheme for heating premises using a heat pump by removing the external circuit along which the refrigerant must circulate and the pump located on the external circuit that pumps antifreeze in the pipe, to generate electrical energy for the pump in the internal circuit using a turbogenerator installed in the external circuit.

This system is distinguished by the fact that instead of the external circuit it contains a water circuit of a hydraulic ram, which will be connected with the internal circuit of the heat pump. In the discharge pipe of the ram, it is assumed that an arcuate tube is placed from the internal circuit of the heat pump. As a result, we have a so-called heat exchanger. And the outlet pipe contains a turbogenerator, which provides power to the pump on the internal circuit.

This design of the system provides an increase in the efficiency of the system compared to the conventional design of the heat pump, the optional use of the external circuit of the heat pump, and therefore the removal of the pump circuit on this circuit, and in the external installation of the turbogenerator, which eliminates the consumption of electricity from the external network when increasing the efficiency of the installation.

Thus, the claimed technical device allows you to implement the inventive method, while being implemented:

1. Exclusion of electrical energy consumption (achieved by removing the pump on the external circuit of the device and installing a turbogenerator on this circuit).

2. Improving the efficiency of the system.

3. Release of the territory adjacent to the object.

It follows from the foregoing that when implementing the proposed method and devices for its implementation, a technical result is achieved consisting in the operation of this device without the consumption of electric energy for the heating system of houses, cottages and summer cottages, in the use of heat of water given to the refrigerant. Elements can be used to generate heat from a heated room, as in a heat pump system. It will be more rational to use the released heat in underfloor heating.

The claimed group of inventions meets the requirement of the unity of the invention, since the application relates to objects of the invention of the same type, of the same direction, providing the same technical result in essentially the same way.

The drawing shows a schematic diagram of the device of such a heat generator. This scheme includes a hydraulic ram on the external circuit and the installation of a turbogenerator in the outlet pipe of the external circuit, two heat exchanger apparatus (interconnecting the external and internal circuit, and between the internal circuit and the heating system: evaporator and condenser), the internal circuit including compressor and throttle.

This device works as follows: when starting the ramming system, water from the source enters through the feed pipe 1 to the shock valve 2 and under pressure H ₁ flows out through it outward with increasing speed. When the speed increases to a certain limit, the pressure on the shock valve from the bottom up increases so that it exceeds the weight of the valve, closes it and blocks the further exit of water to the outside.

In this case, a hydraulic shock will occur, as a result of which the pressure on the feed pipe quickly rises above the pressure in the air cap 4;

Under the influence of this pressure, the discharge valve 3 will open, and water will begin to flow through it into the air cap.

Then the water from the air cap under the influence of excess pressure will go through the discharge pipe 5 to the upper pressure tank 6, rising to a height of H ₂ . After a hydraulic shock, the pressure in the feed pipe will drop below atmospheric pressure and the shock valve 2 will again open under the influence of excessive atmospheric pressure and partially its own weight (or spring). At the same time, under pressure from the water in the air cap, the discharge valve closes and the ramming system automatically returns to its original position.

At the next moment, water will again approach the shock valve through the feed pipe, rush out through the open valve, lift it, cause a water hammer, and the described process will be repeated in the same order.

The ram acts automatically and requires almost no care. The length of the feeding tube is taken equal to (5-8) N ₁ .

Height H ₁ - the vertical distance from the water horizon in the source to the shock valve hole is called the drop height, and the vertical distance H ₂ - from the shock valve hole to the water horizon in the pressure tank is called the discharge height.

Water after passing through the upper pressure tank 6 enters the apparatus-heat exchanger (evaporator) 7.

After the passage of water through the heat exchanger, it is discharged back to the source through the outlet pipe 9 through the damper (regulator) 8, which regulates the pressure of the water passing through the heat exchanger (evaporator) and the turbogenerator 13, which provides electricity to the pump. Heat exchangers are installed in the internal circuit — an evaporator 7 and a condenser 11, as well as devices that change the pressure of the refrigerant — a throttling atomizer 10 in the liquid phase (a narrow calibrated hole) and a pump (compressor) 12 that compresses it in a gaseous state, which operates due to the receipt of electrical energy from a turbogenerator 13 installed in the bypass pipe of the external circuit and working due to the passage of water through the pipe. The liquid refrigerant is forced through the throttle, its pressure drops, and it enters the evaporator, where it boils, taking heat supplied from the pressure head tank with the help of a ram from the source. Since the boiling point of the refrigerant is very low, it turns into gas. Further, the gas into which the refrigerant has turned is sucked into the pump (compressor) 12, compressed and, heated, pushed into the condenser 11. The condenser is the heat-releasing unit of the heat pump: here the heat is received by water in the heating circuit system. In this case, the gas is cooled and concentrated in the liquid, in order to again undergo a discharge in the expansion valve and return to the evaporator. This describes how the device works.

The inventive method and device are industrially applicable, since they include the applied method and devices, complemented by realistically feasible operations, and the circuit itself is supplemented by workable elements that improve its operation.

The proposed method and arrangement of the circuit according to the operating principle provided by the new set of essential features, allows the operation of heating system devices without supplying electrical energy. The advantages of such a heat pump operation scheme include, first of all, cost-effectiveness: there is no need to supply electricity from an external network to transfer 1 kW of thermal energy to the installation. In addition, the heat pump does not burn fuel and does not produce harmful emissions into the atmosphere. It does not require special ventilation and is absolutely safe. All systems operate using closed circuits and do not require operating costs and energy costs necessary for the operation of the equipment. During operation, the system does not need special maintenance, possible manipulations do not require special skills and are described in the instructions.
