Heat pump with own hands from the old refrigerator: heat exchanger circuit, freon-water, self-made controller, split compressor

collect heat pump with your hands is quite accessible to anyone For owners of private home is always an urgent need to house heating. You can use central gas or water heating, but you can explore other options. Such an alternative is a heat pump. You can save by using an independent structure, using old equipment.

principle of operation and the heat pump circuit

heat pumps are able to operate from natural sources EnerGi. The device generates heat without diesel or solid fuel.

The heat pump plays a major role in the arrangement of the heating system. Its construction requires special attention.

The pump itself can not emit heat, it simply carries it into the house. This requires a small amount of electricity. It is sufficient to have a heat pump and an external power source for heating the building. The pump runs in the opposite direction to the refrigerator. Heat is taken from outside and sent to the room.

heat applied draws energy from the earth, water or air

circuit heat pump:

1. compressor - an intermediate element of the system;
2. Evaporator is a low-potential energy transfer element;
3. Throttle valve - it moves freon into the evaporator;
4. Condenser - in it the coolant cools and gives away its heat.

First, energy is released from natural sources and enters the evaporator. Further heat is transferred to freon. In the compressor, the refrigerant is subject to high pressure and its temperature rises. Next, freon is sent to the condenser, where its return to the heating system takes place. The refrigerant is returned to the evaporator, where the process is repeated.

Homemade heat pump from the refrigerator: the steps of creating the

The heat pump is quite an expensive device. But if you want, you can build your own device from an old refrigerator or air conditioner. The refrigeration unit has in its system two parts necessary for the pump - a condenser and a compressor.

Stages of heat pump assembly from the refrigerator:

1. The condenser is first collected. It looks like a wavy element. It is located in the refrigerator from the rear.
2. The capacitor must be placed in a sturdy frame that holds heat well and tolerates high temperatures. In certain cases, it is necessary to cut the packaging in order to install the capacitor without problems. At the end of installation, the container is welded.
3. Next is the installation of a compressor. It is necessary that the unit is in good condition.
4. The function of the evaporator is performed by an ordinary plastic barrel.
5. When everything is ready, you need to fasten the elements together. The heat exchanger is attached to the heating system by PVC pipes.

Before making a heat pump, it is necessary to focus on two points - what is this machine and what are its principles of

As it turns out homemade heat pump. The freon is to be filled by a professional, since the liquid is not easy to work with. In addition, for its injection it is necessary to have special equipment.

Heat pumps from old household appliances are excellent for heating small utility rooms.

The refrigerator can fulfill the role of a radiator. It will be necessary to make two air outlets, which will ensure its circulation. One branch takes cold air, the other - releases hot.

heat pumps Forms: nuances of Freon-water heat exchanger

natural energy source may be a downhole type system, or vodoemnogo precoat. Each option is unique. The principle of operation and installation differs.

When the energy source is a well, it is necessary to drill a corresponding hole in the ground. In 1 m of the source you can get 50-60 watts of energy.20 m will be required for normal operation of the heat pump.

Features of obtaining energy from the well:

1. The main advantages are compactness and high heat dissipation;
2. Minus - difficulties in drilling a well.

When the heat source is ground, the pipe lies below the freezing level of the earth. To lay the pipe, you can dig a trench or trench.

35-50 m of pipe is required for the normal operation of the heat pump

The extraction of energy from the ground is a rather difficult process that requires a large area that will not be available for operation.

If there are ponds nearby, then you can put the pipe in a water source. The main requirement is sufficient depth. In 1 sq. M of water, you can get 30 watts of energy. To fix the pipes at a depth, a cargo is attached to them.

In some cases, air is used as a source. Such a pump contains a refrigerant. In this case, freon comes from the refrigerator. The substance takes heat from the air and gives it to the room.

Controller for heat pump and other elements of water-to-water system

Pipes are placed in the nearest water in a sufficient depth. It is important that the water does not completely freeze. The condenser is connected to the heating system at home. The work itself has 4 stages.

Stages of the water-water pump:

1. The refrigerant receives heat from an external source, heats up and boils;
2. Freon as a gas enters the compressor, where it compresses under pressure;
3. Heat transfer to the heating system, the refrigerant again assumes a liquid state;
4. Freon returns to its original position and is ready to receive heat.

Instrumentation indicators help you to navigate in different situations

The main thing in this system is the compressor. Freon can not self-condense, if the house has a high temperature. This will require increased pressure, which is performed by this element.

So the heat pump takes external heat, adds its own, and also heats up in the compressor. The water source is cooled, and the house is heated. Automation of operation is guaranteed by the controller. All data are marked on the pressure and temperature sensors.

The heat pump has a simple operating principle. Remaking an existing split system requires special knowledge, but you can draw energy from natural sources. They can serve as a well, soil, pond, air.
