Hi all,
I have a customer that requires a full fresh air package unit to replace an Australian Techniaire unit that has come to then end of its useful life. Local supplier Temperzone can't handle a custom unit like this. This is more directed at my Australian colleagues...the specifications are as follows...ignore the separate exhaust part, that is already in place
It is for a Biologically secure facility similar to a dust free area which requires filtered fresh air input and a separate exhaust system maintaining the space pressure at 20 pa below ambient. the minimum airflow is 120l/sec and ideal max is 200l/sec. Cooling requirements is to maintain space temp. at 20 deg C with an ambient air temp. of 32 deg C with an RH of 75% allow for a 2kW solar, lighting and electronic gain
The winter cooling requirement is to maintain a space temperature of 22 deg C with an minimum ambient temp. of 0deg C and a RH of 60%. As the operation is 24/7 the is a need for hot gas bypass deicing of the outside coils in heating mode. we can consider aux electric resistance heating for preheat in low temperature conditions with a maximum of 7kW
Anyone know a supplier that would have a unit to suit?
