The working principle of the air conditioner mainly depends on the cooperative work of its internal condenser, evaporator, compressor, expansion valve and other components.
These components are integrated in an integral chassis, so that the air conditioner integrated machine can provide multiple functions such as cooling and heating. The following is the main working principle of the air conditioner:
1: Cooling mode: In the cooling mode, the compressor runs and discharges heat to the outside through the condenser. At the same time, the evaporator of the indoor unit absorbs the heat in the room to reduce the indoor temperature. This process is realized through the circulation of refrigerant. Under the action of the compressor, the refrigerant becomes high-temperature and high-pressure gas. After being dissipated by the condenser, it becomes liquid, and then enters the evaporator of the indoor unit through the expansion valve, and returns to the indoor heat after absorbing the indoor heat. The compressor completes a refrigeration cycle.
2: Heating mode: In the heating mode, the working principle of the air conditioner is opposite to that of the cooling mode. The compressor runs, absorbs outdoor heat through the condenser (or uses electric heating), and then transfers the heat to the room through the evaporator of the indoor unit, so that the indoor temperature rises. This process also relies on the circulation of refrigerant, but in the opposite direction. Comprehensive utilization of energy: some advanced air conditioning machines also have the function of comprehensive utilization of energy, such as using the waste heat in the refrigeration process for hot water supply, or using the ambient temperature for auxiliary heating in the heating process, so as to improve the energy efficiency ratio and comfort.
Common forms: Common forms of all-in-one air conditioners include window air conditioners, which integrate all components into one chassis and install through windows, which saves space and is convenient to install.
RELATED INFORMATION
What methods can extend the service life of the air cooler?
The air cooler should be installed in a well-ventilated and dry location, avoiding installation in a humid, corrosive gas or dusty environment.
What is the refrigeration principle of the air cooler?
The air cooler is equipped with a water tank and a water circulation system. The water in the water tank is transported to the wet curtain through a water pump (a special fiber corrugated honeycomb material with a large surface area or a multi-layer corrugated fiber laminate).
Advantages and disadvantages of BITZEER' s air-cooled unit
The advantages of BITZER air-cooled units include high efficiency and energy saving, stability and reliability, low noise, and wide application range.
How is the model and specification of the condenser determined?
The first thing to consider is the cooling capacity of the refrigeration system served by the condenser. Cooling capacity is a measure of the ability of refrigeration equipment to absorb and transfer heat from the object being cooled in a unit of time.
What impact will the heat exchange capacity of the condenser have on the refrigeration system?
A condenser with sufficient heat exchange capacity can quickly cool the high-temperature and high-pressure refrigerant gas discharged from the compressor and condense it into liquid.
What are the reasons for the lack of heat transfer capacity of the condenser?
When the condenser is air-cooled, dust will accumulate on its surface after long-term operation.
