The pressure switch is an instrument that opens or closes an electrical circuit, depending on the change of a preset pressure value, in a pneumatic circuit. It is also known as a pressure switch.
In general, pressure switches are mechanical instruments. Its adjustment is made by means of a screw or a small cam, which increases the pressure it exerts on a central spring and this in turn, on the contact or contacts. When the system pressure exceeds that of the spring, the contacts vary in position and conversely, when the system pressure is low and that of the spring is higher, the contacts vary again. With this maneuver, the contacts open or close and allow the central control of the compressor or the corresponding compressed air equipment to carry out the maneuver for which it was designed.
A typical application for pressure switches is starting and stopping small piston compressors. For large compressors and rotary compressors, the pressure switches open or close the contacts so that the central control puts the compressor in charge or discharge, acting on the depressurization valves, in the case of the pistons or on the suction valve, in the case of newspapers.
Pressure switches have also been used for other applications. In security systems controlling high pressure values, such as alarm equipment to activate signals remotely or simply to detect the presence of air pressure in a certain circuit.
In compressed air, pressure switches have been widely used, but little by little they are being banished from industrial applications and replaced by pressure transmitters. These teams have smaller sizes, fewer breakdowns, being simpler mechanics and much higher in operation.
A common image in parking areas: truck drivers leave their engines running for hours to use the air conditioning or to recharge their batteries during their rest periods. This harms the environment, and it is also illegal. Tons of fuel are wasted and it is a huge expense for fleet operators; in addition, they cause faster engine wear. A stationary air conditioner keeps operating costs low. Equally important to fleet owners is the fact that it improves safety on the job, thus ensuring that the driver and cargo arrive safely at their destination.
STOPPED ENGINE COMPRESSOR AIR CONDITIONING SYSTEMS
The air temperature felt by the human body may differ from the actual air temperature. Our thermal sensation can range from hot, through a comfortable temperature, to cold. We all want to enjoy a pleasant climate, and the humidity of the air plays a decisive role. When air humidity is low, we tolerate high temperatures even though we sweat. Dry heat causes sweat to quickly evaporate from the skin with a cooling effect. However, this does not happen in a hot and humid climate, since the humidity of the air is high, reducing the evaporation capacity of sweat and, with it, the cooling effect. Consequently, the sensation of heat is accentuated. The air is humid and sticky, which can lead to circulation problems and insomnia.
Knowing all this, it is obvious what a good stationary truck air conditioner should do. Refrigeration alone is not enough; It is also necessary to reduce the humidity of the air to achieve a pleasant climate.

Introduction
It is mainly used for the installation and modification of trucks, construction machinery, and trucks, all kinds of pure electric vehicles, locomotive tractors, ships, etc.
Operating principle
However, because electric vehicles use DC batteries, if you want the motor to run normally and stably, you need to use a control module (frequency converter) to convert DC to AC. That is, through the voltage control device in the control module, the duty cycle pulse modulation control voltage is added in turn according to a certain rule.
When high-voltage direct current passes through the inverter, a three-phase sinusoidal alternating current is formed at the output end to ensure the smooth operation of the three-phase permanent magnet synchronous motor while generating enough torque to drive the compressor.
lAdvantage
With the advancement of electric vehicle technology and increasing support for national policies, the electric vehicle industry has opened an opportunity to take off. With their own advantages, electric scroll compressors are the most suitable compressors for electric vehicle air conditioners. With the development of the electric vehicle industry, electric scroll compressors for electric vehicle air conditioners also open up good market opportunities
It may take a few days for a truck driver to drive long distances. When a driver encounters a traffic jam or unloads, he may have to wait or rest for a few hours in the car. Some truck drivers have to rest in the car to save money, but when the summer comes The temperature inside the car is very high. It is very likely that heatstroke will be caused by staying in the car for a long time. Now we will bring you a parking cooler to solve this problem for you.

Application
You can choose from the following models:
The engine is the most important part of our vehicle by including a large number of processes necessary to keep it moving and be able to move easily. However, due to its important function, the motor overheats in need of some kind of ventilation to keep it running. For that, we have a fan of the radiator because it dissipates all the heat when directing the air on the surface of the engine.
This component points directly to the center of the radiator and must cool the antifreeze that circulates through the block and thus reduce the temperature of the engine.
There are different kinds of fans depending on the engine conditions:
Manual fixed fan: This fan gets its power to operate from a pulley, which works with a belt from the crankshaft, and never stops. It sucks the air from the radiator to the outside regardless of the speed of the vehicle. It has no enlarges to disengage it or with degrees of inclination on the blades.
Thermal Clutch fan: Consists of a disc-shaped structure, located in front of the water pump and also driven by a pulley. The inside of the clutch has the fluid that produces the internal friction that is hooked with a bi-metallic sensor. When the engine RPM decreases sufficiently, the sensor captures the signal and engages the clutch, which is locked with the fan. The fan will increase its speed when the vehicle’s revolutions are low. When the auto reaches higher speeds and the air hits the radiator, the fan will turn off because it does not have to be used.
Electric fans: These fans are small and powerful. They can be mounted in front of the grill to push the air or behind the radiator to suck it out. Most of these are equipped with withthermal sensors that activate them when high temperatures are reached. Sometimes they are activated after the engine has turned off to bring the temperature back to normal specifications.
Flex fans: They feature a lightweight construction that supports riveted aluminum alloy blades. These have an acritical step between them and, as the number of revolutions increases, the leaves begin to flatten, which produces less resistance when throwing or sucking air operating in better shape and with less noise than the typical blades. This type of fans is used in high-performance cars.
Centrifugal clutch fan: This fan depends on the speed of the motor to engage or disengage from the engine. As the engine accelerates, the clutch allows the fan to partially enter, returning to the engine the energy that would have been used if it had been permanently connected. When the speed decreases, the clutch snaps into position and engages the fan.
At present, it is almost impossible to think of a car without air conditioning (A/C). Especially when we live in warmer cities every day. This device has become one of the main tools in driving, as it provides us with fresh air during our transfers to work or home.
However, the least appreciated moment by many drivers is when the A/C is damaged. Spending long hours with the heat and humidity of the city can be detrimental, especially because it decreases the ability to concentrate and perceive obstacles. In the hot hot summer days are counted in the air conditioner of your car to make the air tolerable inside. So Automotive air conditioning has become an essential part ofour lives, let us know how it works.
How your car air conditioner works
The Air conditioning system in a car includes a cooler and a heater to adjust the temperature and humidity of the vehicle’s interior air to keep you comfortable all the time.
The compressor uses engine power to compress and circulate the refrigerant gas through the system. The refrigerant passes through the condenser (located in front of the radiator) on its way from the compressor outlet to the expansion valve. The refrigerant passes from the expansion valve to the evaporator (located inside the car) and, after passing through the evaporator piping, is returned to the compressor.
When The compressor comes into operation, it pulls refrigerant from the evaporator piping and pushes it into the condenser piping, decreasing the evaporator pressure and increasing the condenser. When the proper operating pressures are set, the expansion valve opens, allowing the refrigerant to return to the evaporator at the same speed as the compressor is removing it. Under these conditions, the pressure at each point of the system reaches a constant level, but the pressure of the capacitor will be much greater than the pressure of the evaporator.
Car’s AC Components
Any Automotive Air Conditioning system consists of 4 basic parts: A mechanical motor-driven compressor of the vehicle;An expansion valve which is a restriction to where the compressor pumps; and 2 heat exchangers; The evaporator and the condenser. In Addition, the refrigerant flowing through the system is required. Here’s what they do:
Auto A/C Compressor:The key to the proper functioning of this system is the compressor, which is in the heart of a/C. system car.The Compressor is the mechanism to vacuum the gas, compress it and put it in circulation through the circuits and other elements. Each system assembles a specific compressor according to the characteristics and capacity of the equipment. The internal mechanism of the compressors may vary according to brands but the result or objective is always the same
Auto A/C Condenser:The Condenser is a fundamental component in the air conditioning of our car because it is in charge of converting the vapor into liquid. The compressor sends the refrigerant vapor to the condenser at high temperatures, which will be cooled by the high pressure from the air that is blown into the condensation coils.
Auto A/C Evaporator:The air conditioner Evaporator of our car is a fundamental element for its correct functioning. This piece is in charge of making the air conditioner of our vehicle come to a cool and pleasant temperature, helping us to fight the heat when we need it most.
Thermal expansion valve:Theexpansion valve separates the high and low pressurezones in the cooling circuit. It is installed in front of theevaporator. To achieve optimum cooling performance in theevaporator, the coolant flow is regulated through the temperature dependent expansion valve. This ensures acomplete evaporation of the liquid refrigerant, so that onlythe gaseous refrigerant accesses the compressor. Expansionvalves can be distinguished from each other by design.
