Split refrigeration units and heat pumps
UNIT
COMPONENTS
Casing made of galvanised sheet steel panels with polyester paint in RAL 7035 white. Free-standing frame. Removable panels to facilitate access.
Outdoor air circuit
Centrifugal fan with a belt drive. Electric motor with tensioner, class F, IP55 and internal heat protection. Dual-inlet impeller, with wheel with forward curved blades. Maintenance-free, lubricated ball socket. Bird screen. Coil comprising copper tubing and aluminium blades. Condensate drain pan.
Setpoint compensation based on the outdoor temperature. Hourly and weekly time schedule. Diagnostic of faults and general alarms. Fire protection. Number of starts and runtime counters for the unit components. Optional functions: Humidity control. Control of auxiliary electrical heaters. Control of an auxiliary hot water coil. Detection of fouled filters. Connection to a centralised management system (CMS) for supervision. This control can include a pGD1 terminal for maintenance as an option, which facilitates initial programming of the unit, modification of operating parameters and a description of alarms which are produced.
Refrigerating circuit
Hermetic scroll type compressor, installed on anti-vibration mounts. Direction of rotation and phase balance control. Crankcase heater. Thermostatic expansion valve with external equaliser and check valve (heat pump units). Four-way valve for reverse cycle (heat pump units). Acid-resistant dehumidifier filter and liquid sight glass. Weldable refrigerant connections. Maximum equivalent length of the refrigerating line is 30 metres (for greater distances, please consult the options).
Casing made of galvanised sheet steel panels with polyester paint in RAL 7035 white. Free-standing frame. Quick access thanks to the removable panels.
Indoor air circuit
Centrifugal fan with a belt drive. Electric motor with tensioner, class F, IP55 and internal heat protection. Dual-inlet impeller, with wheel with forward curved blades. Maintenance-free, lubricated ball socket. Supply and return air outlets on the same front section. Reusable air filters, mounted on a frame. Coil comprising copper tubing and aluminium blades. Condensate drain pan.
Security features
High and low pressure switches. Control of the compressor discharge temperature. Check valve integrated into the compressor. Main door switch. Thermal-magnetic protection for the compressor and fan motor power supply line. Automatic control circuit switch.
