Rotating compressors are generally used in domestic air conditioning compressors
1. Location of installation
Compressors are installed on the right side of the outdoors and are secured on the outer floors; they are connected to the electrical control system by the contours of the compressors and to the refrigeration system by the inhaling and exhausting tubes。
Rotating compressors have interfaces such as inhaling tubes, venting pipes, wiring terminals, gas separators, etc。
Role
Compressors consist of electrical components and compressed components. The main function is to compress low-temperature and low-pressure gases into high-temperature and high-pressure gases。
3. Classification
1 by mechanical structure
There are three common forms of compressor: piston, rotation, vortex:
Rotating compressors are generally used in domestic air conditioning compressors
2 rotating compressors by number of cylinders
Rotating compressors vary according to the number of cylinders and can be divided into single and double-rotor compressors
A single rotor compressor has only one cylinder
The double-rotor compressor has two cylinders, which are mostly used in air conditioners of current high grade or high power。
3. Classification by electricity voltage
Compressors can be divided into communication and direct-flow power, depending on the power supply, which can be divided into 220 v and 380 v。
The exchange of 220v electric compressors is common in 1-3p station-frequency air conditioners
The exchange of 380v electric compressors is common in 3-5p flat-frequency air conditioners, which are usually found in direct or full current-frequency air conditioners, and in early variant air conditioners, which are used in communications。
4. Classification by speed of transmission
The compressor turns at different speeds, which can be divided into antograms and variants
4. High-resolution internal maps
1. Internal structure
Compressors consist of liquid bottles, caps, caps, rotors, caps, etc。
2. Overloaders
(ii) the built-in overloader is installed near the end of the connection
In case of overheating: a deformation of the bi-metal plate following heat to control the disconnection and closure of the protection。
In case of overflows: increased electrical heating of the heat inside the protection, resulting in an increase in the temperature inside the protection, which is ultimately achieved through changes in temperature。
3. Electrical
The electrical component consists of the fixed and rotor。
The compressor coil is embedded in the indent, and the outer coil is used to run the circuit group, the inner coil is to start the circuit group, and is installed together at a rate of approximately 2900 r/min rotor and the compressed component, which is located above and corresponds to the fixed electron。
4. Compression
The compression component consists mainly of cylinders, upper caps, lower caps, scrapes, rolling pistons (rollers), migraines, etc。
The vents are located in the lower air-cylinder caps, with exhaust valves and valve uplift limitrs, and the gases emitted are connected to the compressor's cylinders and to the vents at the top, which means that most of the areas of the compressors are high temperature and pressure。
The inhaler is located above the cylinder and is connected directly to the base copper tube of the liquid tank, which is the equivalent of a compressor inhaling the refrigerant from the evaporation unit into the storage vessel by separating the gas pipe into the tank, so that the gas pump per capita is the refrigerant gas, preventing the hydraulic shocks from the compressor。
5. Rationale
The working principles of the compressed portion of the rotary compressor are shown in the figure for the formation of high-pressure and low-pressure cavities in the cylinder based on the different positions of the rolling pistons。
1) the low pressure cavity has the largest volume and inhalation of refrigerant gases in the inhaler。
2) the rolling piston begins to compress refrigerant gases in the cylinder while the inhaler continues to inhale。
3) the low pressure cavity is equal to the volume of the high pressure cavity, while the low pressure cavity continues to inhale and the high pressure cavity is further compressed, increasing the pressure of the gas until the vent is opened and the high pressure gas is discharged through the vent。
4) the low pressure cavity continues to inhale and the high pressure cavity vent ends。
