Compressor of Air to Water Heat Pump

Compressor is the core part of air to water heat pump  water heater. It is the first factor to determine the quality of air to water heat pump system water heater. Air to water heat pump system compressor is used to compress and drive refrigerant in the refrigerant circuit of air to water heat pump system. The compressor of air to water heat pump system is generally installed in outdoor unit. Air to water heat pump system compressor takes refrigerant from low pressure area and then compressed to high pressure area for cooling and condensation. Heat is emitted through heat sink to air, and refrigerant also changes from gas to liquid state, and pressure increases.

 

The working circuit of air to water heat pump system is divided into evaporation area (low pressure zone) and condensation zone (high pressure zone). The indoor and outdoor units of air to water heat pump system belong to low-voltage or high-pressure areas respectively (depending on the working state). The refrigerant flows from the high-pressure area to the low-pressure area and is injected into the evaporator through the capillary tube. When the pressure drops suddenly, the liquid refrigerant becomes gaseous immediately and absorbs a large amount of heat in the air through the radiator. Thus, air to water heat pump system compressor works continuously, and then absorbs heat at one end of low pressure zone into refrigerant and then sends it to air in high pressure area, which plays an important role in regulating air temperature

 

How does air to water heat pump manufacturers compressor compress gas?

 

Simply say that through changing the volume of gas to complete the gas compression and transportation process! Any power equipment needs a power source to do work, and the compressor is the same. It needs an electric motor (motor) to drive.

 

Whether it is resident air to water at pump or commercial air to water heat pump, volume compressors are divided into two types: back rising plug type and rotary type.

 

1. The reciprocating piston is used to change the working volume of gas through reciprocating movement of piston in the cylinder. The piston compressor has a long history and mature production technology.

2. Rotary compressors include blade (slide) rotary compressors and screw compressors. Most of the domestic air to water heat pump systems are rotary compressors; screw compressors are mainly used for large-scale refrigeration equipment,

The refrigeration system is mainly divided into several equipment:

Compressor condenser throttling device evaporator

The basic principle of this is that the compressor compresses the refrigerant into a high pressure saturated gas (ammonia or Freon), which is then condensed by the condenser.

After throttling through throttling device, it is connected to evaporator to cool and heat exchange medium needed to cool. For example, connect the evaporator to each room in the building, and the snake tube in the evaporator will exchange heat with the air, and then blow the air conditioner into the air of the room through the air blast.

After the refrigerant in the evaporator snake tube is heat exchanger, it becomes low pressure steam and then returns to the compressor, and then compressed by the compressor, so that the refrigeration system is completed by recycling.

 

The heating system is also roughly the principle, but in the opposite way.

 

The compressor in air to water heat pump system water heater is the same as that in the compressor in the compressor refrigeration equipment. It delivers refrigerant to high and high temperature stages in the form of steam at low and low temperatures. The power is usually a motor powered by the main grid and integrated into the compressor. "Electric" is not uncommon in daily life, but it is not the standard for home heating. The sector offers a wide range of solutions, many of which burn fossil fuels such as oil and gas. Therefore, the advantages beyond efficiency are important arguments, such as the need for no tank or natural gas connection (this is usually impossible, especially in rural areas).

 

Whether it is a compressor that is designed air to water at pump or commercial air to water heat pump, air to water at pump manufacturers, the first consideration is refrigerant when selecting the compressor of air to water heat pump system water heater. Compressors must be approved for the required refrigerant and must be suitable for a wide range of applications corresponding to current requirements. Any fluctuation of heat source temperature in a year will determine the required evaporation temperature. For example, if air to water heat pump system water heater is used only during the season - other forms of heating, such as natural gas or oil, are used in winter - the compressor does not need to be suitable for very low evaporation temperatures. Instead, air to water at pump manufacturers must consider the necessary water supply temperature on the condenser side. Whether it is resident air to water at pump or commercial air to water heat pump, an air to water heat pump system water heater and a heating system under the floor form a perfect team. The heating system under the floor does not need high inlet temperature, so it only needs lower condenser temperature, which improves the efficiency of air to water heat pump system water heater. In the worst case, the heating system of an old building has been updated, but its old cast iron radiator has been preserved. These require the highest input temperature - in contrast, modern radiators are usually satisfied with a low 10 km. For cast iron radiators in old buildings, compressors need to be suitable for condenser temperatures up to 65 ° C. Whether it is resident air to water at pump or commercial air to water heat pump, such systems do provide additional assurance that when (or) used to provide hot water, they will not constitute Legionella harm. Temperatures above 60 ° C provide reliable protection against Legionella and the diseases it causes. In fact, if large quantities of hot water are stored at temperatures below 60 ° C, the water should be heated to 60 ° C on a regular basis. Air to water heat pump manufacturers usually try to keep the compressor design as simple as possible, but when a very wide range of applications are needed, additional measures may be taken by air to water heat pump system water heater.
