Résumé

A digital multiple variable refrigerant volume (VRV) air-conditioning system with three-pipe-type heat recovery was designed and researched and is described in this paper. Design and research were conducted on a nominal 30 kW new type multi-connected unit. The system can meet the load of each room by using new type digital scroll compressor with the variable capacity and electronic expansion valves that can automatically control the refrigerant flow for each indoor unit, can achieve the demand of concurrent heating and cooling through the switch of the solenoid valves, and can regulate the heat capacity of the outdoor heat exchanger by using the AC inverter fan in the outdoor unit. The system can run in the heat pump model, refrigeration model or heat recovery model throughout the year and can run in the working temperature range from -18 to 48°C.
