Abstract

The invention discloses a fixed-frequency air-conditioner, a control method of the fixed-frequency air-conditioner, a control device of the fixed-frequency air-conditioner and a computer readable storage medium. The fixed-frequency air-conditioner comprises an indoor heat exchanger, an outdoor heat exchanger, an outdoor temperature sensor arranged on the outdoor heat exchanger, a four-way valve, acompressor, a first electromagnetic valve, a first throttling part, a second electromagnetic valve and a second throttling part, wherein the first electromagnetic valve and the first throttling partare mutually connected in series, and the second electromagnetic valve and the second throttling part are mutually connected in series. The length of a capillary pipe in the first throttling part is smaller than that of a capillary pipe in the second throttling part, a first refrigerant circulating loop and a second refrigerant circulating loop are formed, the first electromagnetic valve is used for controlling the first refrigerant circulating loop to be opened and closed, and the second electromagnetic valve is used for controlling the second refrigerant circulating loop to be opened and closed. The fixed-frequency air-conditioner solves the technical problem that an existing fixed-frequency air-conditioner provided with a single throttling assembly according to the rated working condition is low in energy efficiency under the working condition of low-temperature refrigerating or low-temperature heating.

Description

technical field [0001] The invention relates to the control field of fixed-frequency air conditioners, in particular to a fixed-frequency air conditioner, a control method for a fixed-frequency air conditioner, a control device for a fixed-frequency air conditioner, and a storage medium. Background technique [0002] At present, the length of the capillary tube in the throttling assembly of the fixed-frequency air conditioner is designed and selected according to the rated working conditions, that is, the throttling degree of the throttling assembly is the best under the rated working conditions. For low-temperature refrigeration conditions, the required refrigerant circulation volume is lower than the refrigerant circulation volume under rated working conditions. If the throttling components designed and selected according to rated working conditions are still used, the refrigerant circulation volume will be high, and the degree of throttling will be relatively high. Overwe...
