WIPO Patent Application WO/2018/214767
Kind Code:
A1
Abstract:
A control method for a constant-speed air conditioner comprises: a power source control mechanism in which power is supplied by a mains supply and an emergency control mechanism in which power is supplied by a storage battery are stored; a refrigeration loop of the constant-speed air conditioner comprises a first refrigerant channel and a second refrigerant channel connected in parallel between an outdoor heat exchanger and an indoor heat exchanger; a first throttle mechanism is disposed on the first refrigerant channel, a first electromagnetic valve is disposed on the second refrigerant channel, and the first refrigerant channel is kept in a normally-open state; when the mains supply is interrupted, a controller of the constant-speed air conditioner invokes the emergency control mechanism; the controller divides inputted electric quantity signals of the storage battery into electric quantity signals on different levels, and each level corresponding to an electric quantity signal of the storage battery at the corresponding level; and the controller working according to the emergency control mechanism outputs an electromagnetic valve switch control signal, a compressor switch control signal and/or an indoor fan rotation speed signal. Also disclosed is a constant-speed air conditioner.
