The new air unit works: electric control valve and ventilation interlock Changzhou horizontal air handling units prices to ensure supply valve when the fan is also shut off simultaneously. Electric control valve can also be achieved with the fan interaction, the fan off when the power is turned off the electric control valve. New air unit temperature control system consists of a proportional integral temperature controller installed in the supply air duct temperature sensor and electric control valve. The controller's role is to put air duct temperature sensor detected air temperature is transmitted to the thermostat set temperature controller compares PI calculation based on the results, adjust the thermostat to the electric valve is an on / off signal valve, so that the supply air temperature is maintained at the desired range. Fresh air and central air conditioning unit principle is not complicated, the new air unit is divided into one-way flow, two-way flow of new fans and new fans the total heat exchange, the first two new air unit principle is more simple, but the total heat exchange new wind turbine energy saving temperature Horizontal air handling units control system, works a little complicated Changzhou horizontal air handling unit installation, use effect is the best, of course, the price is the most expensive. When the new air unit deactivated cooler winter water storage located in the basement of the new air unit deactivated after winter frost crack cooler accident occurred, mainly due to air in the new unit has a standing water cooler. Possible reasons are as follows: There is no open damper Changzhou horizontal run air handling units for service (a) cooler discharge, so there is no cooler air into the channel, so the water inside the cooler can not be fully emptying , resulting in reduced winter outdoor temperature after new wind unit cooler cracking. (B) due to a cold water system piping bit Ge in storage, new air handling units and lower than the main pipe system, if the connection line valves closed lax, water in the cold water supply and return water pipeline begins to slowly seep in cooler so despite the draining operation still cause the cracking of accidents. The accident may be the two reasons, one cause, and therefore both areas improved, adding DN15 discharge pipe at the highest point of the supply and return risers new air handling units, air handling units in the new deflated and draining when they can be used, in particular, to ensure the thoroughness of the discharge; and in the fresh air supply and return water on the road of establishing an additional valve unit, completely cut off slow down bleeding problems after discharge.
