For new, the principle of its equipment is not compared with the central air conditioner. At the same time, the new group can be divided into one -way flow, two -way flow, new and full heat exchange.It is simpler, and the later hot exchange of the new energy -saving temperature control system, so the working principle is slightly more complicated, but the effect is also better.
When the cooling is needed, the temperature controller is placed in the refrigeration mode. When the temperature measured by the sensor is reached or lower than the set temperature, the temperature controller gives the electric valve to a valve signal, and the control valve contact of the electric valve is turned on to close the valve.If the measurement temperature does not reach the set temperature, the temperature controller gives an electric valve to open a valve signal, and the electric valve open valve connection connecting the valve to open it.
When the heating is needed, the temperature controller is placed in the heating mode. When the temperature measured by the sensor reaches or higher than the set temperature, the temperature controller gives the electric valve to a valve signal.EssenceIf the measurement temperature does not reach the set temperature, the temperature controller gives an electric valve to open a valve signal, and the electric valve open valve connection connecting the valve to open it.
When the temperature of the tray is too low, the low -temperature anti -freezer switch of the fresh air unit will give a switch signal, and the fan will stop running to prevent the disk from frozen cracking.
Because the core operation of the fresh air unit is the fresh air aircraft, the original power of the general fan will easily cause the functional damage of the fresh air unit, which will affect the normal use of the fresh air system. Like other household appliances, the fresh air unit is like other household appliances. After certainAfter the use of the period, cleaning must be performed, otherwise the performance will not be able to withstand the accumulation of long -term dust, and at the same time, it is necessary to perform maintenance work.
The above is the relevant application operation and maintenance information of the fresh air unit
