Operation range
9
Pump (only EUWYP, EUWYB) The pump circulates the water in the circuit.
10
Pressure regulating valve The pressure regulating valve is used to regulate the water flow in the system.
11
Expansion vessel (only EUWYP, EUWYB) The water in the water circuit expands with rising temperatures. The expansion vessel stabilizes the pressure changes with changing water temperatures by giving free space to the changing water volume.
12
Buffer tank (only EUWYB) The buffer tank reduces the variation in water temperature in the water circuit. This prevents frequent compressor starts and stops.
13
Drain valve The drain valve permits complete drainage of the chiller water system during maintenance or in case of shut down.

14
The water circuit can be filled with water via this fill valve. 15
16
U 7/16 flare pressure ports are provided to connect a device for measuring the pump pressure and the evaporator pressure drop. The waterflow can be deducted from these pressures (Refer to "Figures pressure characteristics" on page 10).
Protect the water circuit against freezing. When the units operate below –5°C and are installed in a rather windy region, a windscreen is required.
17
Displayed unit = EUWYB12KBZW1. The function of the condenser is to change the state of the refrigerant from gaseous to liquid. The heat gained by the gas in the evaporator is discharged through the condenser to the ambient air, and the vapour condenses to liquid. 2
3
Bi-directional flow refrigerant filter The filter installed behind the condenser removes small particles from the refrigerant to prevent blockage of the tubes.
4
6
Pressure port refrigerant circuit These ports make it possible to measure refrigerant pressure in the pipes.
7
Charge valve Allows refrigerant charge in the circuit.
8
19
Water in/outlet connection
Manometer The manometer allows readout of available water pressure to load.
20
Sensor for inlet water temperature The measured inlet water temperature is used by the controller for regulating the outlet water temprature.
21
High pressure gauge (optional) Measurement on high pressure side compressor.
22
Low pressure gauge (optional) Measurement on low pressure side compressor.
23
Liquid receiver The liquid receiver makes sure to only have liquid refrigerant before expansion into evaporator.
24
Evaporator (cooling mode) or condenser (heating mode) The main function of the evaporator is to take heat from the water that flows through it. This is done by turning the liquid refrigerant, coming from the condenser, into gaseous refrigerant.
Ball valve A ball valve is installed in front of and behind the water filter to allow filter cleaning without having to drain the water circuit.
Bi-directional flow expansion valve The liquid refrigerant coming from the condenser enters the evaporator via an expansion valve. The expansion valve brings the liquid refrigerant to a pressure at which it can easily be evaporated in the evaporator.
5

Compressor The compressor acts as a pump and circulates the refrigerant in the refrigeration circuit. It compresses the refrigerant vapour coming from the evaporator at the pressure at which it can easily be liquefied in the condenser.
Water filter The filter installed in front of the pump removes dirt from the water to prevent damage to the pump or blockage of the evaporator. The water filter should be cleaned on a regular base.
(See figure 1)
Condenser (cooling mode) or evaporator (heating mode)
Pressure ports water circuit It is possible to detect any blockage in the water circuit or a malfunction of the pump by means of the 3 pressure ports.
