Conversión de frecuencia o frecuencia fija? Elegir qué enfriador de estacionamiento

    At present, there are many brands of parking air conditioners on the market, including fixed frequency and variable frequency, which puzzles many truck users.
What are the differences between variable frequency Parking Air Conditioner and fixed frequency parking air conditioner?    

1. Different power consumption

The constant frequency parking air conditioner needs to be turned on and off frequently to keep the temperature in the vehicle constant; The variable frequency parking air conditioner can keep the indoor temperature constant only by maintaining low-frequency operation, so the variable frequency parking air conditioner will save more power than the constant frequency parking air conditioner.

2. Different noise levels

When the fixed frequency parking air conditioner is in operation, each frequent startup and shutdown will produce huge noise, affecting the normal rest; Compared with the fixed frequency parking air conditioner, the variable frequency parking air conditioner can keep the indoor temperature constant without switching on and off frequently, so the noise will naturally be smaller.

3. Different comfort

When the constant frequency parking air conditioner operates, there will be a temperature difference within more than ten degrees. The car will be very cold and hot for a while. It feels uncomfortable and can easily affect health; The variable frequency parking air conditioner keeps the temperature in the car constant through low-speed operation, there is almost no temperature difference, the change range will be smaller, the temperature control will be accurate and stable, and the body feeling will be more comfortable.

4. Different cooling speed

The variable frequency parking air conditioner can work at high power supply frequency, and the output power of the internal Compressor will be higher, so that the cooling speed will be faster than that of the constant frequency parking air conditioner.
