Water Source Heat Pump Rooftop Range
The Refrigeration circuit
• Refrigerant R410a• Scroll compressors mounted single or tandem• Thermostatic Expansion valves• Stainless Steel 316 heat exchanger• 4 Way valve for reversibility• Filter drier• High and Low pressure safety switches• Fully assembled and leak tested
Same compressor arrangement as on air cooled version.
Water Source Heat Pump Rooftop Range
The Hydraulic Circuit
As standard the water cooled range will be equipped with the following features:
• Low Pressure Drop (>50 kPa)• Stainless Steel Plate Heat Exchanger• Victaulic Connections & Couplings• Air vent on the highest point • Water filter• Electronic water flow switch• Pressure taps inlet and outlet• Fully insulated hydraulic parts when located inside the unit
Option: Low water loop temperature option through flow control to maintain Refrigerant High Pressure
Water Source Heat Pump Rooftop Range
Electronic flow switch
More Accurate• No risk of offset in time• Very Accurate flow measurementMore Reliability• No moving part• No Maintenance• No risk of blockage• Can work with any kind of fluid (glycol)• One single reference for the whole range• Easy to install• Stainless steel construction
FLOWHeat is dissipated by the fluid
NO FLOWHeat is not dissipated by the fluid
Water Source Heat Pump Rooftop Range
Air Treatment Section
• Identical to the air cooled version, • The performance tables for ventilation / pressure drop remain unchanged
Most of the air treatment features and options are compatible with this new range (Filters, Economiser, CO2 sensors heat recovery modules…)
