Temperature and humidity controller for communication room

Abstract

The invention discloses a temperature and humidity controller for a communication room. The temperature and humidity controller comprises a transformer, wherein a switch K is arranged at an input end of the transformer; an output end of the transformer is connected with an input end of a bridge rectifier; an output end of the bridge rectifier is connected with a controller; the controller comprises a triode BG; a base of the triode BG is connected with an output end a of the bridge rectifier through a variable resistor BT; a base electrode of the triode BG is connected with an output end b of the bridge rectifier; an emitter of the triode BG is connected with a relay J; one end of a switch of the relay J is connected with an input end K of the transformer; the other end of the switch of the relay J is a control end P; a capacitor C2 is connected in series with a resistor R and connected in parallel with the output ends a and b of the bridge rectifier; the base of the triode BG is connected between the capacitor C2 and the resistor R; and a capacitor C1 is connected in parallel with the output ends a and b of the bridge rectifier. The temperature and humidity controller disclosed by the invention is simple in structure, low in manufacturing cost, high in control sensitivity and safe and reliable in working performance, and reduces energy consumption caused by the use of the equipment.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a temperature and humidity controller used in a communication room. Background technique [0002] In order to maintain a high-standard ambient temperature and humidity in the communication room, air conditioners need to be used for adjustment. The power consumed by the air conditioner accounts for about 45% of the production power consumption of the entire computer room. Reducing the energy consumption of adjusting the ambient temperature and humidity of the computer room can greatly reduce Cost of production. Existing temperature and humidity controllers use the expansion liquid in the elastic shell to expand or contract with temperature changes, and the elastic shell elongates or shrinks to generate displacement, and converts the temperature change signal into a displacement signal to control the operation of the device. Its structure is complex , the price is high, and th...
