What Are The Main Components of Air To The Water Heat Pump for Hot Water?

A heat pump is a device that transfers heat from a low-temperature heat source to a high-temperature heat source. Usually used for heat pump devices of low-temperature heat sources is the medium around us - air, river water, seawater, urban sewage, surface water, groundwater, water, fire pool, or from the industrial production equipment out of the working quality, the working quality often has a close to the temperature of the surrounding medium. According to the different low-temperature heat sources, a heat pump can be generally divided into air source, water source, and ground source. Here we will introduce the main components of air to the water heat pump for hot water in detail.

Here is the content list:

• Compressor

• Throttling device

• The evaporator

Compressor

The compressor is part of the air-to-water heat pump for hot water. A driven fluid machine that elevates low-pressure gas to high-pressure. Is the heart of the refrigeration system, it inhales low-temperature and low-pressure refrigerant gas from the suction tube, and drives the piston to compress it through the motor operation. After that, the high-temperature and high-pressure refrigerant gas are discharged to the exhaust pipe, providing power for the refrigeration cycle, to realize the refrigeration cycle of compression → condensation → expansion → evaporation (endothermic). Common types are rotary, vortex, and screw type. Household units generally use rotary type. Commercial units generally use scroll type and screw type.

Throttling device

The throttling device is part of the air-to-water heat pump for hot water. Throttling step-down throttling the medium temperature and high-pressure liquid refrigerant from the condenser to reduce its temperature and pressure. The refrigerant entering the evaporator becomes a wet vapor with a low saturation temperature to ensure that the refrigerant boils at a low temperature to reduce the temperature of the air entering the vehicle. The refrigerant flow rate is automatically adjusted according to the variation of refrigeration load and engine speed so that the refrigeration system always maintains the most suitable cooling capacity. The refrigerant flow rate is controlled according to the temperature at the outlet of the evaporator to ensure the complete vaporization of the refrigerant at the evaporator and prevent the compressor from producing liquid percussion. At the same time, the overheating temperature of the refrigerant vapor is controlled to prevent abnormal overheating. Common throttling devices are electronic expansion valves, thermal expansion valves, and capillaries.

The evaporator

The evaporator is a very important component in the air-to-water heat pump for hot water. Low-temperature condensate "liquid" body through the evaporator, and the outside air for heat exchange, "gas" heat absorption, to achieve the effect of refrigeration. The air source unit adopts a finned evaporator. The water-ground source unit adopts a plate heat exchanger.

Air to the water heat pump for hot water is made up of a compressor, condenser, evaporator, axial flow fan, storage tank, filters, intercepting device and electronic automatic controller, etc. The compressor, condenser, evaporator, and throttling device are called four parts.
