OPERATION & PERFORMANCE
a. The standard voltage of power supply is 380-415V 3N~50Hz, the minimum allowable voltage is 342V, and the maximum voltage is
456V.
b. To maintain better performance, please operate the unit under the following outdoor temperature:
Performance characteristics of the unit
Use conditions of the unit
The air-cooled heat pump modular unit is composed of one or more modules. Each module has its own independent electric
control unit, and the electric control units of modules conduct information exchange through communication network. The
air-cooled heat pump modular unit is characteristics of compact structure and easy transportation and lifting, and in the meanwhile,
it also saves facilities, including cooling tower, cooling pump, and so on, for the user, and reduces installation cost.
The units provide central air handling devices or terminal equipment with chilled water or hot water. The unit is a completely
independent entirety type one, which is designed to be installed outdoors (on the ground or the roof). Each unit includes such main
parts as high-efficient and low-noise scroll compressor, air-cooled condenser, shell and tube (or plate) evaporator, micro-computer
control center, and so on. These parts are installed on steel structure base, so they are sound and durable.
The unit applies Chinese micro-computer control system, which can automatically conduct energy control according to the
magnitude of load, to achieve optimal matching and thus actually realizing optimal energy-saving operation. The product is
modularized unit, and parallel connection of 16 modules can be realized at most, so the user can adopt module combination
according his own demands. The product can be widely applied in air-conditioning engineering of various newly-built and rebuilt
industrial and civil buildings, such as restaurant, hotel, apartment, office building, hospital, industrial plant, and so on. The
air-cooled heat pump modular unit is the best choice for the place which has high requirement in noise and ambient environment
and which is short of water.
