1. Evaporator The evaporator is a very important part of the four major parts of refrigeration. The low-temperature condensed "liquid" body passes through the evaporator to exchange heat with the outside air, "gas" and absorb heat to achieve the effect of refrigeration.
2. Compressor
The compressor is an important part of refrigeration. If the refrigerant is compared to human blood, then the compressor is the human heart, and it is the driving force for the refrigerant to circulate in the refrigeration system. It absorbs the low-temperature and low-pressure gas from the evaporator, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to provide power for the refrigeration cycle. Compressors are divided into piston compressors, screw compressors, centrifugal compressors and so on.
3. Condenser
The condenser is a heat exchanger that cools and liquefies the high-temperature refrigerant vapor compressed by the refrigeration compressor.
4. Throttle valve
The function of the throttle valve is to throttle the saturated liquid or subcooled liquid under the condensing pressure in the condenser to the evaporating pressure and evaporating temperature, and at the same time, adjust the flow of refrigerant into the evaporator according to the change of load.
Principles of Air Conditioning and RefrigerationThe principle of air-conditioning refrigeration refers to the principle of air-conditioning refrigeration operation. After the air conditioner is energized, the low-pressure vapor of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure vapor before being discharged to the condenser. The indoor air continuously circulates to achieve the purpose of lowering the temperature.
The outdoor air sucked by the axial flow fan flows through the condenser, taking away the heat released by the refrigerant, and condensing the high-pressure refrigerant vapor into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and the throttling mechanism, and evaporates under the corresponding low pressure to absorb the surrounding heat. At the same time, the cross-flow fan keeps air entering the fins of the evaporator for heat exchange, and sends the cooled air to the room after the heat is released.
Refrigeration principle of lithium bromide air conditioner The refrigeration principle of lithium bromide air conditioner specifically proposed here is different from compression air conditioners. The working fluid used in absorption refrigeration is usually a binary solution composed of two substances with different boiling points. Among them, low-boiling substances are refrigerants, and high-boiling substances are absorbents. Therefore, binary solutions are also called refrigerant-absorbent working fluid pairs. The so-called binary solution refers to a mixture of two substances that do not have a chemical effect on each other. The various physical properties of this homogeneous mixture (such as pressure, temperature, concentration, etc.) are completely consistent throughout the mixture, and they cannot be separated into the original constituent substances by pure mechanical precipitation or centrifugation.
The refrigeration principle is divided into two parts:
1. The binary solution is heated and boiled by the heat source in the generator, and the refrigerant vapor produced is condensed into refrigerant liquid in the condenser. The liquid refrigerant enters the evaporator after being throttled by the U-shaped tube, and is sprayed under the low pressure condition through the evaporator. The liquid refrigerant evaporates and absorbs the heat of the refrigerant to produce a refrigeration effect.
2. The concentrated solution from the generator will flow into the absorber after being cooled and depressurized by the heat exchanger, and mixed with the original solution of the absorber to form a concentrated solution of intermediate concentration. The intermediate concentration solution is transported and sprayed by the absorber pump, and the refrigerant vapor from the evaporator is absorbed into a dilute solution. The dilute solution is pumped to the generator by the generator, and the refrigerant vapor is generated by the heat source again to form a concentrated solution, which enters the next cycle.

The inner side is smoothly processed, and marked with [R" and [ L " labels in obvious positions to help identify. The line control is near the right earphone. the control area from left to right is previous song, power-on/ Play/pause/hang up the call, next song. The button is made of ABS. It needs to be long press for a long time when it is turned on or off.At the same time, the blue indicator light will always flash once when it is turned on. Three pairs of earplugs, large-medium-small, are included. The actual wearing comfort is not bad, and the physical noise reduction effect is not bad,It comes with a type-C data cable.
After turning on the Bluetooth headphones, the mobile phone can quickly search for Bluetooth. After the first match is successful, it can be connected to the mobile phone quickly next time it is turned on.
As a TWS earbuds, the sound quality is naturally one of the important criteria for judging its excellence. However, different people like different kinds of music, so they have different preferences for sound quality. For example, some people like the deep bass, some people prefer the shock of the high pitch, etc., so this piece is more subjective.
