Temporary Ventilation with Heating
200kw Heating- 35,000m3/hr Air Volume
To provide temporary swimming pool ventilation hire.
Basingstoke Aquadrome required a ventilation system to maintain operation whilst their fixed AHU was replaced. Heating and ventilation are important for providing a comfortable environment in the Aquadrome area. Typically, the temperature in the area needs to be 30 degree’s.
Ten air changes per hour would be required.
For the supply air ACR recommended 2x ACR 160.120 AHU’s and a 200kw heating exchanger system.
For the extract 2x inverter driven axial fans were fitted.
A plate heat exchanger system was recommended as an efficient way to heat the air. A water/glycol mixture is pump through the AHU’s heater batteries and the exchanger. The primary side was fed from the clients LTHW system. This system isolates the primary from the secondary sides- advantages include, more stable temperature control and frost protection afforded by the glycol mix. A tank is fitted to give the head for pumping and to stabilise the temperature in the system.
Because of the distance from the proposed AHU location and the work area, it was decided that the existing AHU’s ductwork would be used. Spigots were fitted to the existing for temporary air connections.
The supply air temperature was controlled by the temporary AHU’s set at 34degrees.
We were really happy with this installation. Flexible ductwork can be tricky to install, however, the careful planning and enabling works really paid off here.
Air delivery to the work area measured well and the space temperature was consistently maintained at between 28-30 degrees. A job well done for this temporary swimming pool ventilation hire.
