Central air conditioner controller and control method

Abstract

The invention discloses a central air conditioner controller which comprises a temperature control panel and a main control panel, wherein the temperature control panel is electrically connected with the main control panel. Information exchange of the temperature control panel and the main control panel adopts the Modbus protocol. The temperature control panel is provided with an on / off key, a wind speed key, a turn-up key, a turn-down key and an LCD. The invention further discloses a control method of the central air conditioner controller. The central air conditioner controller and the control method thereof have the beneficial effects that remote inquiry and air conditioner operation control are achieved; a manager logs in management software on a PC through the Ethernet or the local area network and can conveniently inquire indoor temperatures and operation parameters and operation conditions of air conditioners of each room; and management staff can conveniently turn on or turn off the specified air conditioner and set the operation parameters of the specified air conditioner.

Problems solved by technology

[0002] At present, the central air-conditioning controller has the defects of not saving energy and creating an uncomfortable environment

In the traditional central air-conditioning controller, the air-conditioning wind speed is set through a mechanical switch. Once set, the wind speed cannot be adjusted according to the comfort level of the human body; similar problems, the traditional central air-conditioning controller does not have the ability to monitor the indoor temperature

Therefore, once the air conditioner is turned on, it cannot be turned on or off automatically according to the indoor temperature and the human body's feelings, and blindly cools or heats, resulting in energy waste; moreover, in northern regions, such as Harbin, when there are no people in the room, the management will turn it off for energy saving air conditioner

In this way, because the traditional air conditioner controller is non-intelligent, it may cause the indoor temperature to be lower than the safe value, freezing water pipes and other facilities; in addition, the management side cannot know the indoor temperature and the working status of the air conditioner, let alone control the temperature of the air conditioner.
