Refrigerant Leak Detection
The refrigerant leak detection is located below the condenser fan to ensure
correct operation. The leak detector has three factory settings of 100, 1000
and 2000 parts per million. The default is 1000 parts per million.
The leak detector has relay outputs allowing for alarm monitoring via the
Airedale controller.
This relay output can provide facilities for refrigerant pump down (Airedale
unit model dependant) for refrigerant containment.
The detector module is IP rated for outdoor applications.
Pump Down Refrigerant pump down shall automatically occur in the event of a refrigerant
leak.
Remote Electronic Expansion valve The new EVD Evolution REEV has been developed in conjunction and for
sale primarily with the new BluCube condensing unit; however the REEV
can be applied to applications using other manufacturer’s equipment with
capacities up to 2050kW
The REEV product has been designed for applications where an Outdoor
Condensing Unit is to be matched with an indoor Air Handling Unit. It is
provided in situations where it is unsuitable to have an expansion valve
driver local to the outdoor unit due to the maximum wire lengths between the
valve driver and the valve itself being exceeded. This is down to the valve
driver’s manufacturer’s recommendations.
The REEV will provide a versatile solution that is capable of dealing with
various refrigerants, multiple network options and multiple numbers of
refrigeration circuits.
Further information can be found in the REEV technical Manual.
