Heat pump for heating (definition)

Heat pump for heating — is a device for transferring heat energy from one place to another by means of a compressor and the circulation of a refrigerant through a system of heat exchangers. It can both heat and cool rooms and is used in heating systems, ventilation and air conditioning (HVAC).

Heat pump for heating: main components and operating principle

1. Evaporator - absorbs heat from the environment (air, water or soil), converting the refrigerant from a liquid state to a gaseous state.
2. Compressor - compresses the gaseous refrigerant, increasing its temperature and pressure.
3. Capacitor - transfers heat from the refrigerant to the heating or hot water system, converting the refrigerant back to a liquid state.
4. Expansion valve - reduces the pressure of the refrigerant before it returns to the evaporator, completing the cycle.

Types of heat pumps for heating:

• Air to air — transfer heat between the outside air and the air inside the room.
• Air-water — transfer heat between the outside air and the water heating system.
• Water-water — use heat from underground water or reservoirs for a water heating system.
• Soil-water — use heat from the ground for a water heating system.

Advantages of heat pumps for heating:

• Energy efficiency - heat pumps can produce 3-4 times more heat than they consume in electricity.
• Environmental friendliness - they use renewable energy sources and reduce carbon emissions.
• Versatility — can be used for both heating and cooling of premises, as well as for heating water.

Applications of heat pumps:

A heat pump for heating can be installed in residential, commercial and industrial buildings. These units provide efficient heating and cooling and can also be used in hybrid systems. HVAC together with traditional heat sources such as gas or electric boilers to improve the overall efficiency of the system.

Heat pumps are an environmentally friendly and cost-effective solution for providing a comfortable microclimate in various types of buildings.
