Air Conditioner Manufacturing Principle The working principle of industrial air conditioner

How does an air conditioner work:

The conditioning and refrigeration system consists of a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator and a blower. Copper pipes (or aluminum pipes) and high-pressure rubber pipes are connected into a closed system between the components. When the refrigeration system is working, the refrigerant circulates in this closed system in different states, and each cycle has four basic processes:

1. Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas and discharges it out of the compressor. 2. Heat dissipation process:

The superheated refrigerant gas at high temperature and high pressure enters the condenser, and due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid and discharges a large amount of heat. 3. Throttling process: The volume of the refrigerant liquid with higher temperature and pressure becomes larger after passing through the expansion device, and the pressure and temperature drop sharply, and the expansion device is discharged in the form of mist (fine droplets).

4. Endothermic process: the mist refrigerant liquid enters the evaporator, so the boiling point of the refrigerant is much lower than the temperature in the evaporator, so the refrigerant liquid evaporates into gas. During the evaporation process, a large amount of surrounding heat is absorbed, and then the refrigerant vapor at low temperature and low pressure enters the compressor.

This process is repeated to reduce the temperature of the air around the evaporator. The refrigeration principle of an air conditioner is the same as that of a refrigerator. The compressor is used to turn the liquid refrigerant into gas, absorb heat in the evaporator, and circulate it to the condenser to dissipate heat to achieve the purpose of refrigeration.

The heating principle is the reason why the air conditioner adds a four-way reversing valve to turn the condenser into an evaporator. The circulation of the refrigerant is powered by the compressor. The use of compressor emptying is to turn off the low-pressure valve, loosen the low-pressure pipe, start the compressor, and quickly tighten the low-pressure pipe when the low-pressure pipe has no air to discharge.

After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and discharged to the condenser. At the same time, the outdoor air drawn in by the axial fan flows through the condenser, taking away the heat released by the refrigerant, causing the high-pressure refrigerant vapor to condense into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure to absorb the surrounding heat.

At the same time, the cross-flow fan continuously enters the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release. In this way, the indoor air is constantly circulating and flowing to achieve the purpose of reducing the temperature.

It is the principle of exothermic when a gas becomes a liquid, as described in junior high school physics. I wonder if it can help you solve your doubts?

Landlord, what do you want to ask?

There are three types of industrial air conditioning systems on our side: AHU system, MAU system, and FCU system. Its working principle is basically the same, hot and cold exchange.

The MAU can control the temperature and humidity, while the AHU and FCU can only control the air temperature.

Air conditioners are divided into single-cooling air conditioners and dual-purpose air conditioners, both of which work on the same principle. The refrigerant used in air conditioners was freon, which has the property of releasing a large amount of heat when it changes from gaseous to liquid state.

When the liquid state changes from a gaseous state, it absorbs a large amount of heat. Air conditioners are designed based on this principle.

The compressor compresses the gaseous freon into a gaseous freon at high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes liquid freon at room temperature and high pressure, so the outdoor unit blows hot air. Then to the capillary, into the evaporator (indoor unit), because the freon from the capillary to the evaporator after the space suddenly increases, the pressure decreases, the liquid freon will vaporize, into gaseous low temperature freon, thereby absorbing a large amount of heat, the evaporator will become cold, the fan of the indoor unit will blow the indoor air from the evaporator, so the indoor unit blows out of the cold air.

When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water. Then the gaseous freon returns to the compressor to continue compressing and continuing the cycle.

There is a component called the four-way valve during heating, so that the flow direction of Freon in the condenser and evaporator is opposite to that of refrigeration, so when heating, cold air is blown outdoors and hot air is blown in the indoor unit.
