Discharge check valve of compressor

The installation of a check valve on the discharge of Turbocor compressor is mandatory to prevent the compressor rotating backwards on shutdown as well as pressure from the condenser flowing backward through the compressor to the evaporator when the compressor is  shut down. While there is little to guide the service technician regarding the maintenance/… Leia mais Discharge check valve of compressor

Condenser Approach

CONDENSER APPROACH On a chiller with water cooled condensing, this is the difference between the saturated temperature of the discharge pressure and the leaving condenser water temperature.  On a high efficiency chiller with flooded type condenser, this should normally be no more than 1 to 2 degrees C (1.8 to 3.6 degrees F).  Where historical… Leia mais Condenser Approach

Evaporator Approach

EVAPORATOR APPROACH Evaporator Approach is the difference between the saturated temperature of the suction pressure and the leaving chilled water temperature. Normally, in a high efficiency chiller with a flooded type evaporator, the evaporator approach should be less than 2 degrees C. (3.6 degrees F.). When historical information on a unit is available, it is… Leia mais Evaporator Approach

Correct charge level in chiller with flooded evaporator

DETERMINING CORRECT CHARGE IN A CHILLER WITH FLOODED EVAPORATOR Determining when a Turbocor compressor based chiller is very different as compared to a DX type system. All units should have a nameplate which should include the design charge of the system.  On smaller systems, if there is doubt about the charge, system charge can be… Leia mais Correct charge level in chiller with flooded evaporator

Determine cause of failure – A must

COMPLETE SERVICE MUST  INCLUDE IDENTIFYING THE CAUSE OF ANY FAILURE Training courses offered by Danfoss Turbocor and the various OEM manufactruers that use the Turbocor compressor focus on how to identify and correct problems with the Turbocor compressor. I have frequently seen situations where there is one type or another of a failure, the technician… Leia mais Determine cause of failure – A must
