What are the different types of air conditioning control in a car?

Hello landlord, car air conditioner will be divided into cooling or heating according to function, we generally call the heating function heater, and the refrigeration is called air conditioning. The heating warm air is made by using the principle of cooling circulation of the water tank of the vehicle itself. The refrigeration air conditioner is a vehicle-mounted refrigeration system, including compressor, evaporation tank, drying bottle, etc., and the control switch is AC switch.

The on-board blowing system is formed separately, that is, the fan system, that is, there is a knob or switch that specifically controls the fan gear, which is divided into several gears. That is to say, under the premise that the fan is working, the refrigeration AC switch can be turned on again to have the cold air out, or the warm air control valve can be opened again to have the heat blown out. If this is the case, there are three types of air conditioning in a car, that is, the heating system, the cooling system, and the air supply system.

Automotive air conditioners can be divided into independent air conditioners and non-independent air conditioners according to the drive mode. Independent air conditioner is equipped with a special auxiliary engine as the power source of the compressor (such as bus air conditioning), while non-independent air conditioning is directly driven by the main engine of the car (such as car air conditioner and truck air conditioner).

Hello, there are three kinds, 1Mechanical hand controller, control damper and cycle mode with cable; 2.Electric controller with servo motor to drive the damper and cycle mode; 3.

The automatic controller, with a computer module, automatically controls each damper, circulation mode and wind speed according to the temperature set point, i.e. the environmental state. Thank you.

1.According to the control mode, it is divided into manual type (toggle the function keys on the control board to control the temperature, wind speed, and wind direction).

2.Electro-pneumatic adjustment (using the vacuum control mechanism, when the air conditioner function button is selected, it can be automatically controlled within the predetermined temperature.)

temperature and air volume).

3.Fully automatic adjustment (using the calculation and comparison circuit, the adjustment mechanism is controlled by the sensor signal and the preset signal, and it is automatic.)

Adjust the temperature and air volume) and fully automatic adjustment of microcomputer control (with microcomputer as the control center to realize the air intake in the car.

all-round, multi-functional optimal control and regulation).

Generally, it includes a refrigeration device, a heating device and a ventilation device, which makes full use of the limited space inside the car, has a simple structure and is easy to operate, and is an internationally popular modern automobile air conditioning system.

1. According to the drive mode, it is divided into: independent (a dedicated engine-driven compressor, with large refrigeration capacity and stable operation, but high cost, large volume and weight, mostly used in large and medium-sized buses.)

and non-stand-alone (air-conditioning compressors.

Driven by automobile engine, the refrigeration performance is greatly affected by the engine work, and the stability is poor, and it is mostly used in small buses and cars).

2. According to the performance of air conditioning, it can be divided into: single function type (the refrigeration, heating and ventilation systems are installed separately, operated separately, do not interfere with each other, and are mostly used in large buses.

and trucks) and cooling and heating integrated (refrigeration, heating, chain ventilation share blower and air duct, control on the same control board, working can be divided into cold and warm air work separately combined and cold and warm air can work at the same time mixed temperature control type. Cars are mostly used with mixed temperature control).

3. According to the control mode, it is divided into manual type (toggle the function button on the control board to control the temperature, wind speed and wind direction) and electro-pneumatic adjustment (using the vacuum control mechanism, when the air conditioning function key is selected, it can be automatically controlled within the predetermined temperature.

temperature and air volume).

4. According to the control mode, it can be divided into: automatic adjustment (using the calculation and comparison circuit, through the sensor signal and presetting signal to control the adjustment mechanism to work, and automatically adjust the temperature and air volume) and the automatic adjustment of microcomputer control (with the microcomputer as the control center, to achieve all-round, multi-functional optimal control and adjustment of the air environment in the car).

According to the function, it can be divided into power supply and electrical equipment. The power supply includes batteries, generators, regulators, and power distribution systems. Electrical equipment includes start-up system, vehicle electric system, lighting, instrumentation, signal, alarm system, air conditioning system, entertainment system, other equipment (anti-theft, network, comfort, security system, etc.), the whole vehicle circuit and power distribution device and automotive electronic imitation finger control system.

Manual, automatic, single-zone, dual-zone and triple-zone.

The role of car air conditioning is to cool or heat, air conditioning is a comfort configuration, and the car is equipped with air conditioning to increase the comfort during driving or riding. The heating principle of the car air conditioner is very simple, after turning on the heating function, the high-temperature coolant in the engine will flow through the warm air water tank, and the air blown by the blower will pass through the warm air tank, so that the air conditioning outlet can blow out the warm air.

Modern car air conditioners have four functions, any of which is designed to make passengers feel comfortable.

1) The air conditioner can control the air temperature in the cabin, which can not only heat the air, but also cool the air, so as to control the temperature in the cabin to a comfortable level;

2) The air conditioner is able to exhaust moisture from the air. Dry air absorbs human sweat to create a more comfortable environment;

3) The air conditioner can inhale fresh air and has a ventilation function;

4) The air conditioner can filter the air and remove dust and pollen from the air.

The principle of the automatic control system of automobile air conditioning is to control the working state of radiator fan, condenser fan, compressor clutch, blower motor and its air control motor according to the output control signals detected by each sensor in the car, such as the temperature in the car, the temperature of the evaporator, the temperature of the engine coolant and other relevant switching signals, so as to realize the automatic control of the temperature in the car. The following is the extended information:,1. The automotive air conditioning system is referred to as the automotive air conditioning system, and the main purpose is to provide a comfortable interior environment for the driver in any climate and driving conditions.

A complete car air conditioning system is to achieve the purpose of creating a comfortable environment in the cabin by adjusting the temperature, humidity, wind speed and air exchange, among which the temperature in the car is one of the important indicators of comfort. 2. The effect of automobile air conditioning is closely related to the quality of body insulation and the degree of heat transfer of glass, in order to reduce the heat load in the car, it is necessary to pay attention to the sealing and thermal insulation of the cabin. The car air conditioning system generally does not need to do special maintenance, but due to the influence of the external environment, the purification device of the air conditioner and the evaporator of the air conditioner need to be cleaned regularly to maintain good air conditioning quality.

Automobile air conditioning system is referred to as automobile air conditioning system. Its main purpose is to provide passengers with a comfortable in-car environment in any climate and driving conditions. A complete set of vehicle air conditioning system, by adjusting the temperature, humidity, wind speed, ventilation, etc., can be bright to achieve the purpose of creating a comfortable environment in the car, in which the temperature in the car is one of the important indicators of comfort.

The internal temperature depends on the outside temperature, air flow, and solar radiation. When the outside temperature exceeds 20 degrees Celsius, the internal temperature can only be cooled by the air conditioner cooling vertical width. Generally, low-grade vehicles use traditional manual air adjustment.

On the control panel, there is a temperature adjustment knob, which is actually a variable resistance device. It forms a series circuit with a temperature-sensing resistor in the evaporator. When the temperature changes, the resistance value of this set of circuits changes, which controls the electromagnetic clutch of the compressor.

The exterior is manually adjusted by means of a knob. This method of adjustment is relatively simple, but the temperature control is not precise enough.

The effect of the CAR air adjustment is closely related to the thermal insulation quality of the car body and the degree of heat transfer of the glass. In order to reduce the heat load in the car, it is necessary to pay attention to the tightness and thermal insulation of the car. Cars

What is the method of adjusting the air conditioner in a car? What is the method of adjusting the air conditioner in a car? The way to adjust the air conditioner of a car is:

Press the AC button under the center console. The role of automobile air conditioning: 1. Control the temperature in the car; 2. Remove moisture in the air and create a comfortable driving environment; 3. Fresh air can be inhaled to keep the air fresh in the car; 4. It can filter the air and remove dust and pollen from the air.

Maintenance methods of automobile air conditioners: 1. Clean the air outlet of the air conditioner in time; 2. Dismantle and maintain the air conditioning condenser in time; 3. Clean or replace the air conditioner filter in time. Ways to use air conditioning wisely:

1. Turn off the air conditioner when driving at low speed; 2. Do not smoke when the air conditioner is turned on in the car; 3. Turn off the heat first and then turn off the air conditioner; 4. Start the internal circulation immediately when entering the car in summer. @2019

1.Compressor collision sensitivity: Driven by the engine, the low-temperature and low-pressure refrigerant vapor generated by endothermic vaporization in the evaporator is continuously sucked in, and the high-temperature and high-pressure refrigerant vapor is formed after compression, which is discharged to the condenser to create high-pressure conditions for the continuous condensation and exothermy of the refrigerant in the condenser.

At the same time, the circulating flow resistance of the refrigerant in the refrigeration circuit is overcome.

2.Condenser: The heat contained in the high-temperature and high-pressure refrigerant steam discharged from the compressor is released to the outside air flowing through the condenser, and the refrigerant steam is condensed into a refrigerant liquid with a certain degree of supercooling.

The condenser is mostly arranged in front of the cooling water tank at the front of the car, which is cooled by the cooling fan and the windward airflow generated by the car's driving.

3.Reservoir dryer: When the refrigeration system is running, the liquid refrigerant is filtered, dried and hygroscopic and temporarily stored. A sight glass is often installed above it to observe whether the refrigerant is filled with sufficient and whether the flow is normal (the refrigerant should be foam-free and flow smoothly).

4.Expansion valve: throttle and depressurize the high-pressure refrigerant liquid from the reservoir dryer to form a low-temperature and low-pressure mist refrigerant, which is sprayed into the evaporator. The flow rate of refrigerant injected into the evaporator can be automatically adjusted according to the temperature of the outlet refrigerant steam of the evaporator.

5.Evaporator: The low-pressure refrigerant liquid at this low temperature continuously evaporates and vaporizes, absorbs the heat flowing through the air of the evaporator, and cools the air in the cabin. The evaporator is arranged in the car compartment and is usually supplied by a centrifugal fan.

6.Air conditioning pipeline: It is made of aluminum hard hose and rubber hose crimping, connecting all parts of the refrigeration system.

7.Refrigerant: The vaporization of the refrigerant in the evaporator absorbs the heat of the air in the cabin to achieve refrigeration, and the condensation in the condenser releases heat to the air outside the vehicle.

A car generally consists of four basic parts: engine, chassis, body, and electrical equipment.
