OPERATION & PERFORMANCE

a. The standard voltage of power supply is 220V 3N~ 60Hz, the minimum allowable voltage is 198V, and the maximum voltage is 242V. 
b. To maintain better performance, please operate the unit under the following outdoor temperature: 

Operating range under cooling mode

Operating range under heating mode

10

ć

~52

ć

-10

ć

~21

ć

c. The unit is of outlet water temperature control mode
Outlet water temperature control—cooling: minimum temperature 5

ć

, maximum temperature 17

ć

; heating: minimum temperature 

45

ć

, maximum temperature 50

ć

.

If low-temperature water outlet unit is required, it should specially be customized. 

        If the user requires the unit to operate under the outlet water temperature is lower than 
the minimum setting value mentioned above, be sure to make the requirement to the dealer or 
our maintenance center, and necessary protective measures should be taken before the unit 
is used. 

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.
