Constant temperature and humidity machine how to debug

The operating system of constant temperature and humidity machine adopts touch screen and control module to stop the setting, monitoring and automatic adjustment of menu parameters. Specific methods are as follows: after the air-conditioning system is energised, the touch screen enters the system operation preparation state after self-checking and stops the system parameter setting.

Indoor temperature and humidity parameter setting: According to the design requirements, the return air temperature T is set to 22 ℃, relative humidity is 40%. Constant temperature and humidity machine humidification lower limit is set to 37.0%, stop humidification upper limit is set to 43.0%. In other words, when the return air humidity is lower than 37%, the humidifier works. When the return air temperature is higher than 43%, the humidifier stops working.

The lower limit for opening the electric damper is 40% and the upper limit for closing it is 43%. In other words, when the return air humidity sensor of the system dehumidifier detects that the return air humidity is lower than 40%, the motorised damper opens. When the return air humidity is greater than 43%, the electric damper closes. the upper limit of power loss of the reversing valve is 60 min, and the energising time is 120 s. The power loss time of the reversing valve is the normal working time of the dehumidifier. When the accumulated time reaches this time, the electromagnetic reversing valve carries out electric defrosting, and the defrosting time is 120s for the energising time of the reversing valve. the energising and de-energising of the reversing valve should be cycled in accordance with this procedure.

Due to the influence of temperature and humidity sensor accuracy, equipment location and transmission line length, there is an error between the set return air parameters and the actual measurement results. It is not necessary to stop the compensation of return air temperature T and return air humidity to stop the correction. The specific practice is to evenly distribute points in the indoor space of about 1m height according to the size of the air-conditioned space, and stop using high-precision mercury thermometer and hair hygrometer for measurement.
