Room temperature control for a number of once-through systems, the new wind not only make the environment meets health standards, but also bear all the indoor load. Because the indoor load is changed, then use the inevitable way to control the supply air temperature can not meet indoor requirements (possibly too hot or too cold). It is necessary to control the temperature of the place of use. It can be seen, when the temperature sensor must be located in a typical area controlled room. Since the current system is generally provided with ventilation systems, temperature sensor located in the exhaust pipe and to consider certain amendments also a viable option. When cooling is required, the thermostat placed in the cooling mode when the temperature sensor is at or below the set temperature, the thermostat for electric valve shut off valve contacts a valve signal, the electric valve is turned the valve closed. If the measured temperature does not reach the set temperature importing fresh air unit, a thermostat valve open valve to the electric signal, the electric valve open contact to put the valve open. When you need fresh air heating unit, thermostat placed in the heating mode ambitious new air unit, when the temperature sensor is at or above the set temperature, the thermostat for electric valve shut off a valve signal, the electric valve contact to put the valve closes. If the measured temperature does not reach the set temperature, the thermostat to the electric valve a valve opening signal, the electric valve open contact to put the valve open. Safe operation of the proposal must be provided with effective antifreeze interlock monitoring device controlled fresh air unit design. Fans must first ensure the rated water flow heater is running, when the water temperature is too low or the water flow is too small and should be promptly closed alarm fresh air blower and fresh air of the population holding unit damper Without full protection measures with prison actually just semi-finished products In the cold winter put into operation without security and can not "job."
