- product introduction:System introduction
The constant temperature and humidity control system is to control the indoor temperature, humidity and cleanliness within a certain fluctuation range to meet the requirements of the indoor environment for special occasions such as industrial production and scientific research. For example, in some operating rooms, the room temperature is required to be maintained throughout the year (24 soil 2) C, and the relative diffusion is maintained (50+10)%.
The application areas of constant temperature and humidity system are: hospital operating department, electronic factory, pharmaceutical workshop, cigarette factory, measurement, textile, optical instruments and other fields.
Fresh air intake section
Including fresh air valve, inlet air temperature control function 1) fresh air valve: linkage with the blower, provide fresh air to the room when it is carried out, cut off the input of fresh air when stopping, 2) inlet air temperature control function: including inlet air temperature sensor, electric preheating, high temperature fuse: according to the detection signal of the inlet air temperature sensor installed behind the electric preheating, control the start and stop of the electric preheating, ensure that the inlet air temperature is within a certain positive range, the function of the high-temperature circuit breaker is to limit the working temperature rise of the electric preheating and protect the unit.
Filter function segments
Including the initial effect, medium effect, high efficiency catcher filter during use, need to react in real time filter blockage, filter on both sides of the installation of differential pressure switch, by detecting the differential pressure value on both sides of the filter, compared with its own set value, if the set value is exceeded, send an alarm signal to remind maintenance personnel.
The blower control function section
Including blower control, loss of air differential pressure switch. 1) The control function of the blower, including the blower, inverter, and air pressure sensor, controls the output frequency of the blower inverter according to the air pressure sensor signal to achieve constant pressure air supply. 2) Loss of wind pressure differential switch: during the operation of the unit, real-time detection of the pressure difference on both sides of the outlet and return air of the supply fan
The own settings are compared. An alarm signal is issued in the event of a fan failure.
Table cold feature segment
Including cold water generation, return air/brand air temperature float control function, antifreeze switch. 1) More temperature and humidity signals feedback from the return air/exhaust temperature and humidity sensor, control the opening of the cold (hot) water valve of the meter, and realize the function of heating (cooling) and dehumidification:
2) Antifreeze switch: only winter works, if it occurs, the hot water valve immediately opens to the maximum, within 3 minutes, if the antifreeze switch can be automatically reset, the hot water valve with return air / exhaust temperature signal normal operation, if after 3 minutes, the antifreeze switch has not automatically reset, the unit stops running, and sends an alarm signal to notify the maintenance personnel for maintenance.
Reheat the functional segment
Including electric reheating, high temperature circuit breaker, return air/exhaust air temperature control function 1) according to the temperature signal feedback from the return air/exhaust temperature and humidity sensor, control the number of electric heating starts, that is, control the amount of heating (or open the hot water valve to control the amount of hot water) to achieve the heating function, 2) The function of the high-temperature circuit breaker is to limit the working temperature rise of electric heating and protect the unit.
Humidification function section
Including humidifier, return air/exhaust diffusion control function, according to the humidity signal feedback from the return air/exhaust temperature and humidity sensor, control the humidification amount of electric humidification, and realize the humidification function.
Fire damper functional section
Once the fire valve is activated, the unit and its auxiliary equipment all stop running, and an alarm signal is issued to notify the maintenance personnel to carry out maintenance.
Exhaust function section
Linkage with unit and automatic door.
Winter and summer conversion function
When the control cabinet "cooling/heating" transfer switch is set to the automatic state, the system automatically determines that the system is cold/hot water according to the water temperature detection switch on the water supply main, which can be forced to summer/winter mode by the "cooling/heating" transfer switch
