Embodiment Construction

[0022] figure 2 It is a schematic structural diagram of the central air conditioner provided by the present invention. image 3 It is a structural block diagram of a central air conditioner temperature detection device for preventing overload. Such as figure 2 As shown, the central air conditioner provided by the present invention includes a plurality of indoor units 140 respectively arranged in each indoor space. The indoor unit 140 includes an indoor heat exchanger 142 and an indoor fan 144, and is connected to an outdoor unit 180 installed in an outdoor space through a refrigerant pipe. An inverter compressor 182 and a fixed-speed compressor 184 are installed on the outdoor unit 180, and these compressors can compress the refrigerant circulating in the system into a state of high temperature and high pressure. Wherein, a lubricating oil separator 186 for separating refrigerant and lubricating oil is installed on the discharge end of the variable frequency compressor 18...

Abstract

This invention discloses a kind of outdoor fan controlling method when air conditioner is overloading. It includes: whether air conditioner is overloading is judged; if it is overloading, then the outdoor fan air-quantity is adjusted to the minimum. If it is normal, the outdoor fan keeps the set air-quantity. This invention can adjust outdoor fan air-quantity from the set air-quantity to the minimum air-quantity under overloading refrigeration. Thus, heat exchanging rate of outdoor heat exchanger is reduced to prevent the refrigerants temperature flowed from outdoor heat exchanger is lower than the estimated temperature. It adjusts outdoor fan air-quantity from the set air-quantity to the minimum air-quantity under overloading heating. Thus, it avoids the refrigerants temperature flowed from outdoor heat exchanger is higher than the estimated temperature.

Description

technical field [0001] The present invention relates to a control method of an air conditioner, in particular to an air conditioner in an overload state which can effectively eliminate the overload state by properly adjusting the air volume when the air conditioner is in an overload state during cooling or heating. Outdoor fan control method. Background technique [0002] Air conditioners are usually installed in spaces such as rooms, living rooms, offices, or shopping malls, and can regulate indoor air temperature, humidity, pollution, and airflow, thereby providing people with a comfortable indoor environment. Air conditioners are generally divided into two types: integrated type and split type air conditioner. Although the all-in-one and split-type air conditioners have the same function, the all-in-one air conditioner has a cooling and heat release device inside a casing, and is installed in a wall hole or on a window. The split-type air conditioner is to install a coo...
