How to use Prima air conditioning button?
The air conditioning button is the switch of the air conditioning compressor. Only when the compressor is turned on can the air conditioner have refrigeration capacity, otherwise only the natural wind from outside blows into the car, which can't meet the refrigeration demand of passengers in the car in summer.
Maximum air conditioning
This function only appears on some automatic air-conditioning models. After MAX is pressed, the air conditioner compressor and blower will use large output to reach the set temperature as soon as possible. After the MAX function is started, the air conditioner in the car will run at full load, with large fan air volume and loud noise. However, this function is very practical for riders who need to get comfortable temperature as soon as possible after starting.
Internal circulation and external circulation
Some cars will be equipped with two buttons (also lever type) for internal circulation and external circulation. For models equipped with two buttons, the illuminated button is the corresponding mode. For those with only the internal circulation button, the internal circulation light is turned on in the internal circulation mode, otherwise it is in the external circulation mode.
Internal circulation and external circulation refer to the passage of air flow in the car. When it is in the internal circulation state, the air inside the car does not exchange with the outside world, which is beneficial to keep the temperature inside the car stable. However, keeping this state for a long time will lead to low oxygen content in the air inside the car, dirty air, and passengers' fatigue, which is not conducive to the health and safety of passengers.
The external circulation function introduces some fresh outside air, but it should be noted that in places with poor air quality, opening the external circulation may actually reduce the air quality inside the car, so the external circulation is still opened in places with reasonable air quality.
Zone temperature control and synchronous temperature control
Some high-profile models have the function of zone temperature control, that is, the temperature can be adjusted by zone. Taking a vehicle with dual-zone temperature control as an example, it can be divided into left and right zones to control the temperature respectively, in which the "SYNC" button can control the opening and closing of zone operation, zone startup and zone control of the temperature inside the vehicle. Manual air conditioners are all controlled synchronously, so it is impossible to adjust the temperature in different zones.
Automatic key point
AUTO means automatic. When you turn this function on, the air conditioner in the car will automatically adjust the wind speed according to your preset temperature. For example, it is appropriate to set the temperature inside the car at 20 degrees in advance. If the temperature inside the car is higher than the set temperature, the system will automatically adjust it to a high wind speed to quickly cool down. If the temperature inside the car later drops to the set temperature, the air conditioner will automatically reduce the wind speed. In a word, AUTO is a constant temperature control function, and it is not necessary to manually adjust the wind speed frequently.
