Detailed Product Description

Ground Source Heat PumpIntroduction:
Vicot VWS series are designed with high efficiency scroll or semi-hermetic screw compressors to be utilized in commercial and industrial air conditioning, be suitable for indoor installation. The units provide the ideal solution for sound sensitive environments. Compact design makes installation more flexible. The units are incorporated with microprocessor control system allowing to monitor and manage all the functions and to communicate with external management system.
The units are completely assembled in the factory, supplied with full refrigerant change and control equipments, to reduce time and costs. The installation normally requires just hydraulic and electrical connections

Features:
1) Compressors
Adopting scroll and screw compressors in the unit. Screw type compressor is direct male motor/female motor drive, with crankcase heater. Lubrication is ensured by discharge and suction pressure difference. Continuous cooling capacity control is available, enabling to maximize the energy efficiency of the unit in any operating condition, integral electric motor protection and temperature sensors are inserted directly to the windings. Motor starters are delta-star type and are supplied with standard capacity step reduction
2) Heat exchangers
Shell and tube type, dry expansion evaporators are insulated with closed-cell foam material for reduced heat loss. All evaporators are incorporated with temperature probe for anti-freeze protection
3) Refrigerant circuit
Includes: compressor discharge valves, liquid lines shut-off valve, charging connector, liquid line sight glass, filter drier, thermostatic expansion valve, low pressure control with automatic reset, high pressure control with manual rest, evaporator and condenser water temperature probes for readout by unit control system
4) Electrical control panel
5) Control and safety devices
