M G A - D 65 S N Refrigerant N1 R410A N R407C - R Power Supply S 80V~, 50Hz, Ph General introduction Air-cooled heat-pump unit is a kind of central air conditioner which adopts air as the cooling (heating) source and water as cooling (heating) medium. As a sort of integrated equipment, it need no cooling tower cooling water pump boiler and corresponding auxiliary parts such as pipe system etc, which makes the structure simpler, saves installation space, convenient maintenance and energy saving. Thus it is very suitable for areas that are short of water. Air-cooled heat-pump unit is the first priority in the engineering design for the following conditions: Hot suer and cold winter. No heating boiler and heating-supply pipe system. Heating supply pipe system is unstable or the supplying time is short. Need air-conditioning whole year.

21 Air-cooled Modular Chiller System PMV refrigerant flow adjustment Traditional modular chiller adopts thermo-expansion valve for adjusting, but it cannot adjust refrigerant flow accurately and also will be delay. So it makes the room temperature fluctuating too much that users may be uncomfortable. High efficient heat exchanger For the 0 or 65kw module, we use plate heat-exchanger, and for the 00 kw module, we use shell-andtube heat-exchanger. Chiller water outlet temperature can be adjusted ater outlet temperature can be adjusted according to customers' demand. In cooling mode, the adjustable ranges from 7 0 C to 1 0 C, and in heating mode, it ranges from 45 0 C to 50 0 C. Simple control The wire connection is very simple between modules. The signal wiring connection between two units of 65 module is finished before launch. The two-cores Shielded Twisted Pair is used for signal wire. Each unit can be controlled and monitored by the wiring controller that just connects to main unit.
