air conditioning requirements.
Working principle of Combination Household (Townhouse) Central Air Conditioning Unit: Firstly, the
unit products cools (or heat) water, after being pressed by water pump, this cooled (heated) water will be
transferred to each indoor fan coil by water pipe (or other terminal facilities), and then through fan coil to
conduct heat exchange with indoor air circle make indoor air temperature lower (or higher), for the purpose
of air conditioning adjustment. Meanwhile, fresh air unit can be installed in the system to introduce certain
quantity of fresh air into rooms after ltering or lowering (or heating up) temperature so that indoor air can
still remain fresh and comfortable.
There are 3 parts that mainly combines into Combination Household (Townhouse) Central Air
Conditioning System.
①
Household (Townhouse) Central Air Conditioning Unit which divides into of
cooling only and heat pump. Outdoor units are usually placed at outdoor balcony, roof or special at roof;
indoor units can be placed in washing room or other indoor places. Outdoor and indoor units can also be
piled up together in outdoors. ② Terminal facility: Mainly indicates fan coil. Horizontal concealed fan coil is
usually recommended to simplify indoor tment. ③Water system: For connecting host and terminal fan coil
to transfer cool and heat. It is commonly made of galvanized pipe or seamless steel pipe. It can also adopt new
types of pipes such as PVC pipe, PPR pipe, or aluminum-plastic pipe etc.
2. Product Features
1) Humanized design, i.e. both split installation and integral installation are available.
2) Ultra-thin indoor unit design whose height is only 288mm to make hoisting easy.
3) Adopting casing heat exchanger to enhance unit performance, antifreeze ability and reliability.
4) System realized trinity
A set of heat pump system can both cool and heat, it saves gas system, and also collocate with household
replace, water boiler or city heating net. Thus, cooling, heating, and water heating become trinity.
5) Large range of cool water and heat water supply
When cooling, supply range for cool water is 7
℃～15℃
; when heating, supply range for heat water is
35
℃～50℃
.
6) High reliability
Heat transfer media of this unit is water and with no distance limitation, only considering enough water
pump lift can realize long-distance heating and cooling.
7) Control function in subrooms
It is available to conduct on or off control to host in rooms, that is, when order of turning on from only
a single room, host on; when all rooms send unit off order, host off; general control spot can be set at living
room to conduct prior control to unit.
8) Easy operation
Adopting advanced total computer control system, main control system can conduct complete control to
the unit. Since it is very easy and quick to reset the operation, it can satisfy users’ requirements. With multi-
point control function, it is available to control on/off of host from several rooms, i.e. when order of unit on
from only a single room, host on; when all rooms send unit off order, host off; general control spot can be set
at living room to conduct prior control to unit.
9) Easy dialogue interface
Host displays in English, and every operation data can be nd. When malfunction occur, unit will displays
error informational automatically, thus, repair and maintenance is very easy.
