  • Page 27: Refrigerant Description

    ESIE07-06 Piping Layout Refrigerant Description The low temperature refrigerant gas coming form the evaporator to the compressor cools the electric motor. Later it is compressed and during this phase the refrigerant is mixed up to the oil coming from the separator. The high-pressure oil refrigerant mixture is conveyed inside the oil separator of centrifugal high efficiency type.

  • Page 28: Evaporator

    Piping Layout ESIE07-06 Evaporator The evaporator is flooded shell-and-tube with the refrigerant out the tubes and the water inside them. Normally no maintenance and service operation is required. When it is necessary to replace a tube it is easy to remove the old one. 1–14 Part 1 –...

  • Page 29: Condenser

    ESIE07-06 Piping Layout Condenser The condenser is shell-and-tube with the refrigerant out the tubes and the water inside them. The condenser tubes are externally finned and expanded on the tube plate. All units have an integrated subcooling in the condenser also equipped with a safety valve. If required it is possible to remove and replace the tubes.

  • Page 30: Liquid Control Valve And Float Valve

    Piping Layout ESIE07-06 Liquid Control Valve and Float Valve The Danfoss SV(H) float valve + PMFH main valve + pilot solenoid valve combination is used to maintain a constant liquid level within a shell and tube condenser on the high pressure of the system. The float valve is attached to the vessel by branch connections at a point corresponding to the desired liquid level.
  • Page 31 ESIE07-06 Piping Layout When the liquid level within the vessel rises, the float within the SV(H) float chamber also rises, raising the float arm. The float arm actuates a needle valve. As the float rises, the needle valve is withdrawn from its seat and opens the float valve orifice, relieving pilot pressure PS through the orifice.

  • Page 32: Refrigerant Level Sensor

    Piping Layout ESIE07-06 Refrigerant Level Sensor The level sensor includes a floating element checking the refrigerant level inside the condenser and controlling the expansion valve indirectly monitoring the refrigerant flow. A regulating valve, installed on the sensor flange, allows to level stabilizing. This valve is factory set during the test and normally does not require any further adjustment on the field unless on particularly unstable plant where an additional regulation must be operated from qualified personnel only.

  • Page 33: Compressor

    ESIE07-06 Piping Layout Compressor The compressor is controlled by a special motor, installed on the end of the main driving shaft. It consists of two screwed cast iron element: the main one includes all moving parts as the main rotor and the two satellites, the second element includes the three-phases 2-poles electric motor.

  • Page 34: Compressor Operation

    Piping Layout ESIE07-06 Compressor Operation With the single-screw compressor the refrigerant suction, compression and discharge process is operated by a continue flow for each satellite. During this operation the volume is progressively reduced compressing the refrigerant. After the compression, the gas is discharged through the ports properly designed.

  • Page 35: Capacity Control

    ESIE07-06 Piping Layout 2.10 Capacity Control Capacity control The compressors are provided with infinitely variable capacity control as standard. This system allows mechanism unit load to be equal to plant demand. Stepless capacity control is permitted by a pair of sliding valves, fitted in the compressor, one for each half of the symmetrical compression process.
  • Page 36 Piping Layout ESIE07-06 SOLENOID SOLENOID CAPACITY CONTROL ACTION VALVE A VALVE B Load compressor Oil is vented from the capacity control cylinder. The De-energised action of the suction/discharge differential pressure on Energised (open) (close) the slide/piston assembly overcomes the force of the unloading spring and moves the slide valve towards the maximum load position.

  • Page 37: Oil System Control

    ESIE07-06 Piping Layout 2.11 Oil System Control Each screw compressor is connected to a tank (oil separator) separating and collecting the oil from discharge gas. The discharge gas pressure pushes the oil into the compressor where, after passing through a high capacity filter, it is conveyed to the main injection port for compressor seal and lubrication of all moving parts.

  • Page 38: Lubrication Oils

    Piping Layout ESIE07-06 2.12 Lubrication Oils Besides lubricating the bearing and other moving parts, the oil has the equally important task of granting the seal during the compression, improving the efficiency. Therefore more oil is injected than is required for lubrication alone. Lubricating oil approved by McQuay is mentioned on the compressor label.

  • Page 39: Liquid Injection

    ESIE07-06 Piping Layout 2.13 Liquid Injection The liquid injection is used to cool down the compressor when the discharge temperature becomes higher than 85°C. All units produced from August 2009 have this control standard on the unit. This liquid injection is optional for units manufactured before August 2009. Oil Injection Discharge Line...

  • Page 40: Oil Recovery System

    Piping Layout ESIE07-06 2.14 Oil Recovery System Each compressor includes a system to recover the oil accumulated inside the evaporator during the normal operation. This system consists of a set pump able to collect continuously all the oil from the evaporator preventing from the accumulation due to the low speed refrigerant gas.

  • Page 41: Heaters

    ESIE07-06 Piping Layout 2.15 Heaters The compressor and the oil separator are supplied with resistances for heating the compressor and the oil inside the separator, to prevent the migration and the condensation of the refrigerant during shutdown unit. The auxiliary circuit should be energised for at least 12 hours prior to start up compressor. The compressor and oil temperatures should be sufficiently high before starting the system lowering at the minimum problems of lubrication and liquid blows.
