Machine room air conditioner control system with simulation instrument

Abstract

The invention discloses a machine room air conditioner control system with a simulation instrument. The control system comprises a unit controller, a touch display screen, a return air temperature and humidity transducer, an outlet air temperature and humidity transducer, a suction pressure transducer, an exhaust pressure transducer, a suction temperature transducer, an exhaust temperature transducer and a current transducer. An analog extension module, the return air temperature and humidity transducer and the touch display screen are all connected with the unit controller; a switching power supply is connected with the touch display screen; the suction temperature transducer, the exhaust temperature transducer, the compressor current transducer, the suction pressure transducer, the exhaust pressure transducer and the outlet air temperature and humidity transducer are all connected with the analog extension module. According to the invention, no external refrigerating system detecting instrument is needed during debugging, repairing and maintaining of a machine room air conditioner; the machine room air-conditioner control system with a simulation instrument can be used for visually simulating various measuring instruments and displaying concrete values, is provided with a function of user maintenance guidance, can be used for detecting the performance state of the unit in real time, and has the advantages of convenience for user, environment friendliness and reliability.

Description

technical field [0001] The invention relates to a control system of an air conditioner, in particular to a computer room air conditioner control system with a simulation instrument. Background technique [0002] Computer room air conditioners are often used in places with high environmental requirements such as program-controlled exchange rooms and computer rooms. When debugging, repairing and maintaining computer room air conditioners, maintenance personnel must carry relevant system testing instruments and install them on corresponding testing points. , these instruments are very inconvenient to carry, install, and use. Moreover, during the use of maintenance personnel, a small amount of refrigerant will be lost in the air, polluting the environment; When the air conditioner fails and shuts down, predictive maintenance cannot be carried out. These failures are generally relatively serious. If the air conditioner in the computer room is not repaired in time, the ambient tem...

[0002] Computer room air conditioners are often used in places with high environmental requirements such as program-controlled exchange rooms and computer rooms. When debugging, repairing and maintaining computer room air conditioners, maintenance personnel must carry relevant system testing instruments and install them on corresponding testing points. , these instruments are very inconvenient to carry, install, and use. Moreover, during the use of maintenance personnel, a small amount of refrigerant will be lost in the air, polluting the environment; When the air conditioner fails and shuts down, predictive maintenance cannot be carried out. These failures are generally relatively serious. If the air conditioner in the computer room is not repaired in time, the ambient temperature and humidity will deviate from the original control range. Over time, it protects These computer room equipment will be destroyed
