Component
Function / remark
1
Compressor
A hermetically sealed scroll compressor.
2
Water-heat exchanger
(evaporator)
The water-heat exchanger is of the brazed plate-heat
exchanger type.
3
Air-heat exchanger
(condensor)
The air-heat exchanger is of the cross fin coil type. Hi-X-tubes
and PE coated waffle louvre fins are used. The air is discharged
upwards.
4
Fan
Direct driven single or two speed motor.
5
Expansion valve
The thermostatic expansion valve is set up to control the
superheat between 5°C and 7°C.
6
Low-pressure switch
This switch acts as a circuit safety.
■
Standard setting: OFF = 2 bar ± 0.3
■
Standard setting: ON = 0.2 bar ± 0.2
■
Glycol application setting: OFF = 1.5 bar ± 0.3
■
Glycol application setting: ON = 0.5 bar ± 0.2
7
High-pressure switch
This switch acts as a circuit safety.
■
Standard setting: OFF = 21.6 bar +0/-1
■
Standard setting: ON = 30.9 bar +0/-1
8
Strainer
This strainer prevents dirt particles from entering the expansion
valve.
9
Water in- and outlet
connections
The water in- and outlet connections are made of galvanized
steel pipe (British Standard Pipe - BSP). The pipes are not
insulated.
If copper field piping is used for the water circuit, then precau-
tion should be taken to prevent electrolytic corrosion.
10
Low-pressure
service port
The low-pressure service port is used to connect a
low-pressure gauge.
11
High-pressure
service port
The high-pressure service port is used to connect a
high-pressure gauge.
