The Concept of Heat Pump and the Introduction of Working Principle

JIANGSU SUNCHI NEW ENERGY CO.,LTD. has the most professional technical team to create the best quality heat pump devices. Below SUNCHI will introduce you to the concept of heat pump and how it works:

Heat Pump is a device that transfers the heat energy of low-level heat sources to high-level heat sources. It is also a new energy technology that has received worldwide attention. It is different from the familiar mechanical equipment that can improve the potential energy - "pump"; heat pumps usually obtain low-grade heat from natural air, water or soil, work through electricity, and then provide people with accessible high grade thermal energy.

The working principle

Water flows from a height to a low place. Heat is transferred from a hot object to a low temperature object. This is the law of nature. However, in real life, people use pumps to pump water from low places to high places for the needs of agricultural irrigation, domestic water use, etc. Similarly, in today's increasingly energy-intensive, heat pumps are used to transfer heat energy from low-temperature objects to high-temperature objects in order to recover heat from low-temperature hot gases that are normally discharged into the atmosphere and low-temperature hot water that is discharged into the river. Then hot objects are used to heat water or heat to make full use of the heat.

The working principle of the heat pump system is consistent with the working principle of the refrigeration system. To understand the working principle of the heat pump, we must first understand the working principle of the refrigeration system. The refrigeration system (compression refrigeration) generally consists of four parts: a compressor, a condenser, a throttle valve, and an evaporator. The working process is as follows: a low temperature and low pressure liquid refrigerant (for example, Freon) is first absorbed in a vaporizer (for example, an air conditioner indoor unit) from a high temperature heat source (for example, room temperature air) and vaporized into a low pressure vapor. The refrigerant gas is then compressed in the compressor into a high temperature, high pressure vapor. The high-temperature and high-pressure gas is cooled and condensed into a high-pressure liquid by a low-temperature heat source (for example, cooling water) in the condenser, and then throttled into a low-temperature and low-pressure liquid refrigerant through a throttling element (capillary, thermal expansion valve, electronic expansion valve, etc.). This completes a refrigeration cycle.

Ground-source heat pump is a kind of heat pump. It is an air-conditioning technology that uses buildings or water as a source of cold and heat to cool buildings in winter and cool in summer.  Ground-source heat pumps simply "shift" energy between the earth and the interior, using minimal power to maintain the temperature required in the room. In the winter, 1 kilowatt of electricity sends 4-5 kilowatts of heat from the soil or water into the room. In the summer, the process is reversed, the heat in the room is transferred to the soil or water by the heat pump, so that the room gets cool air. The energy obtained underground will be used in the winter. This cycle combines the architectural space with nature to achieve the most comfortable living environment at the lowest cost.
