Chinese patent application 00221147.5 discloses an indoor unit of a cabinet-type air conditioner. The indoor unit of the cabinet-type air conditioner has low noise, high efficiency, stable motor speed, and good low-speed performance of the fan. The disadvantage is that the air conditioner suddenly During a power outage, the air conditioner is shut down, and when the power is restored, it is necessary to manually restart and set the air conditioner
In actual use, such a situation is often encountered, such as a sudden power failure in places requiring constant temperature such as cultural relics preservation rooms, library rooms, and computer rooms, which cause the air conditioner to shut down. If there is no one on duty during non-working hours or holidays, it will have a negative impact on the preservation of items in places that require constant temperature due to large changes in ambient temperature

Abstract

The invention discloses air conditioner indoor set and window type air conditioner circuit device as well as circuit-breaking method to open a terminal, which consists of central control circuit and working state circuit-breaking memory circuit of two-direction electric connection with electric erasing-writing type storage, wherein the electric erasing-writing type storage air conditioner can set itself working state according to the data in advance when the power is broken suddenly then supplied again; the working mode refers to refrigerating mode or heating mode; the air conditioner judges whether enters into corresponding working mode according to the environmental temperature. The invention can be used in special occasion of environmental requirement.

Description

technical field [0001] The invention relates to a circuit device of an indoor unit of an air conditioner, a circuit device of a window type air conditioner and a power-off and start-up method of the air conditioner. Background technique [0002] The purpose of the air conditioner is to keep the indoor temperature or humidity within a certain range. Existing air conditioners other than central air conditioners can be divided into split air conditioners, integral air conditioners, and one-to-many air conditioners. Split-type air conditioners include ceiling-mounted, wall-mounted, and floor-standing (also called cabinet-type), etc.; integral air conditioners are mainly window-type. The so-called split means that the air conditioner is divided into two parts: an indoor unit and an outdoor unit; usually, the indoor unit of an air conditioner mainly refers to the indoor unit of a split wall-mounted air conditioner and the indoor unit of a split cabinet air conditioner. Chinese p...
