Household wall-mounted split air conditioners are divided into frequency conversion and fixed speed. The wall-mounted split air conditioner with the same horsepower has the ability to adjust the indoor temperature, and the variable frequency wall-mounted split air conditioner is greater than the fixed-speed wall-mounted split air conditioner. The frequency conversion wall-mounted split air conditioner is relatively cost-effective and more energy-efficient. In addition, the frequency conversion wall-mounted split air conditioner can achieve precise temperature control and prevent "wall-mounted split air conditioners" in certain procedures.
1. Electricity cost of fixed-speed wall-mounted split air conditioner:
① The startup current of the fixed-speed wall-mounted split air conditioner is several times the rated current, and the fixed-speed wall-mounted split air conditioner is frequently turned on and off during operation, which consumes electricity.
②The fixed-speed wall-mounted split air conditioner keeps heating at the rated high power during operation. After the room temperature rises to the set temperature of the wall-mounted split air conditioner plus 1 degree, the wall-mounted split air conditioner stops. After the wall-mounted split air conditioner is stopped, when the room temperature drops to the set temperature of the wall-mounted split air conditioner minus 1 degree, the wall-mounted split air conditioner starts again, and the cycle repeats. The same goes for refrigeration.
③The fixed-speed wall-mounted split-type air conditioner has insufficient heating capacity in winter, with electric auxiliary heating elements, and the energy efficiency ratio is only 1. The electric auxiliary heating power of the fixed-speed wall-mounted split air conditioner is 1~2kW, which consumes electricity.
