Air-conditioning intermediate controller

Abstract

The invention is an air conditioner intermediate controller, belonging to the electric appliance field, where controller panel is equipped with multiple output terminals respectively connected to user end controllers, and the terminals are connected to control circuit in the machine casing; the control circuit can execute output ON-OFF control and comprises sensors monitoring all end load operating current and total load current sensor providing overcurrent protection function and connected in power supply loop; the controller panel is equipped with signal I / O control terminals connected with host machine controller. And it controls central air-conditioner set by any air-conditioner end load operating current; starts or stops end controller operation by the control signal the central air-conditioner set transmits, so as to implement bidirectional control and achieve purpose of saving energy.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to an air-conditioning intermediate controller used between an air-conditioning unit controller and a terminal controller. Background technique [0002] In the field of centralized air conditioning applications, the production of air conditioning units and fan coil units belongs to different professional manufacturers. Each manufacturer usually only independently develops its own products and corresponding controllers. At present, among domestic and foreign manufacturers of centralized air-conditioning controllers, most of their products use single-chip microcomputer technology to independently control centralized air-conditioning units or independently control the end exchanger of the air-conditioning——the fan coil unit. There is no control system for system control of both. Air-conditioning users often hope that the entire air-conditioning system can be turned on ...

AI Technical Summary

Problems solved by technology

That is to say, the current situation in the field of air conditioning control is: the controller of the air conditioning unit only controls the work of the air conditioning unit, and the terminal controller of the air conditioner only controls the work of the terminal of the air conditioner. The controllers of these two products lack connection with each other, and can only be controlled independently, so that the entire air conditioning system cannot be fully coordinated and controlled from the perspective of one system

The current controller exposes many inconveniences during the operation of the air conditioning system

For example: when the main engine of the central air conditioner shuts down for some reason, but the terminal controller can still continue to work, that is, the main controller cannot control the work of the terminal controller. At this time, it is still necessary to manually close all the fan coils; When people leave the building, all the fan coil units have been turned off, but the main unit of the air conditioner is still running, that is, the terminal controller cannot control the work of the main unit, and the idling of the main unit causes energy waste
