7 EKV energy saving producing hot water EKV HEAT RECLAIM (DS option) In general, the practical use of waste energy is called heat recovery. Refrigeration plants with air-cooled condensers produce a lot of waste energy by dumping the condensation energy to the ambient air. By installing a BPHE desuperheater, a large proportion of this waste energy can be turned into hot water that may be used for many purposes such as: n room heating n sanitary hot water n hot water for processes Desuperheater option - HOW IT WORKS An additional BPHE (brazed plate heat exchanger) is installed in series between the screw compressor and V-shaped air-cooled condenser. Depending on the temperature requirement for the hot water production this exchanger will act as to recover the heat up to 20% of the total heat. As a desuperheater the sensible heat from the hot discharge gas will be recovered, while the latent heat exchange will occur in the air-cooled condenser; by this way the efficiency of the unit is sustained as condensing pressure can be reduced due to aircooled condenser becoming oversized. Hot water temperatures up to 55 C can be achieved. The total amount of available superheating depends on the difference between the discharge temperature from the compressor (point A in Figure) and the condensing temperature of the refrigerant gas (point B). 7

28 Outstanding efficiency VFD - Inverter technology available The option VFD makes it possible to increase drastically the efficiency at part loads. By working always with the maximum efficiency an inverterdriven compressor equipped with ACVR (automatic continuous Vi regulation) can really offer impressive energy savings. A case study of a process cooling unit with air-cooled condenser showed about 25% energy saving in one year for instance. INVERTER AVAILABLE Latest generation screw compressors New compact screw compressors offer the highest efficiency both at design (EER) and seasonal (ESEER) conditions, thanks to the optimized fluid dynamics and the latest design and manufacturing technologies. Easy installation and accessibility thanks to all main fittings and checks on just one side. Designed for heavy-duty operation and equipped with top quality components. Single-pass S&T evaporator The single-pass shell&tube dry expansion evaporator is equipped with a unique patented refrigerant distribution system which has been optimized for R134a. The configuration counter-current of the flow is design to maximize performance and the plastic baffles are used to improve the water side performance and to avoid corrosion issues. 28

29 application software ekapt The application software ekapt developed for EKV chillers allows an easy access to the machine configuration and management parameters with the menu system organised by device. There are three password levels to allow three different access modes to the parameters (read only for assistance, edit for servicing, total access for the manufacturer). The main screen gives quick access to the user functions without a password (information on the status of the machine components, On-Off and machine operating mode, set points). PID control There are two types of PID control: - PID control on start-up - PID control during operation [kw] The start-up control must prevent an excess of requested power. Since at start-up the status of the load is not known but only the temperature is, the power must be entered little by little, waiting for the reaction of the system. The control during operation must be quick in order to follow any load variations and maintain the water temperature as close to the set-point value as possible. Compressor s envelope management The operating limits (hereafter defined as envelope) of the compressors are controlled. This control cannot be disabled in order to prevent the compressor from working outside of the safety limits dictated by the manufacturer. All of the compressors inserted thus contain the envelope data. When the operating condition is outside of the envelope, the alarm delay starts counting: if the operating condition remains outside of the envelope when the delay has elapsed, a specific alarm is activated, which stops the compressor; if, on the other hand, the operating condition returns within the envelope limits, the alarm delay counter is reset. Compressors power distribution ekapt application software provides management of the power distributed to the compressors in the best way possible to increase the efficiency of the unit. The behaviour of power distribution changes depending on the configuration, 1, 2 or 3 circuits and the power ratio between compressors. In the event of an alarm for one compressor, the next available compressor will be turned on as a replacement if the request is high enough. For units with two circuits and prevention active in one circuit, the rotation will compensate for the limited circuit by increasing the request on the available circuit. 29
