B A Drainage oil in the Oil supply gt lt li gt lt compression chamber NC NC 2 A Slide Spring valve Exhaust pressure action on this end of the piston The compressor is factory equipped with a perpetual control system for its own capacity The shutter valve reduces the groove s intake capacity and reduces its actual length The shutter valve is controlled by the pressure of the oil from the separator Part 1 System Outline 1 67 Piping Layout ESIE07 03 2 8 Shutter Valve Control Introduction The shutter control method is described in the figures below One end of the shutter valve is shaped like a hydraulic piston installed in a cylinder near the compressor exhaust The other end contains a spring The change in volume elaborated by the compressor takes place by alternating the force on the valve piston group Internal holes allow the pressurised oil to communicate with the capacity control cylinder and allow its drainage The solenoids normally are closed NC and open when powered During operation of the compressor the position of the valves is controlled by the pressure within the cylinder The oil under pressure is introduced into the cylinder and acts on a surface that is larger than the piston thus ensuring greater thrust than that resulting from the exhaust pressure plus the force of the spring In this way the valve is brought to load the compressor If the cylinder is u

79. After the liquid vapour refrigerant has been evenly distributed in the direct expansion evaporator tubes it exchanges heat with the water to be cooled thus reducing its temperature and it gradually changes state until evaporating completely and then overheating Once it has reached the overheated vapour state the refrigerant leaves the evaporator and is once again taken into the compressor and restarts the cycle Part 1 System Outline 1 63 Piping Layout ESIE07 03 2 5 Compressor The series 3100 single screw compressor is of the semi hermetic type with asynchronous three phase two pole engine which is directly splined to the main shaft The intake gas from the evaporator cools the electrical engine before entering the intake ports Inside the electrical engine there are temperature sensors completely covered by the coil winding that constantly monitor engine temperature Should the coil winding temperature become very high 120 C a special external apparatus that is connected to the sensors and to the electronic controller will de activate the corresponding compressor There are only two moving rotating parts and there are no other parts in the compressor with an eccentric and or alternative movement The basic components are therefore only the main rotor and an upper satellite that carry out the compression process meshing perfectly together Compression sealing is done thanks to a suitably shaped special composite m

Unload lt Load Slide Spring Discharge pressure acts on this side of piston HSS 3100 series compressors is provided with infinitely variable capacity control as standard Since the compressor utilizes fixed intake and discharge ports instead of valves the overall compression ratio is determined by the configuration of these ports The degree of compression is governed by the ratio between the flute volume when it is sealed off by the star tooth at the beginning of the compression process to that immediately before the discharge port is uncovered This is known as the built in volume ratio VR and is an important characteristic of all fixed port compressors In order to achieve maximum efficiency the pressure within the flute volume at the end of the compression process should equal the pressure in the discharge line at the instant the flute volume opens to discharge Should these conditions not prevail either over compression or undercompression will occur both of which result in internal losses Although in no way detrimental to the compressor inefficient compression will increase power consumption The slide valve is housed in a semicircular slot in the wall of the annular ring which encloses the main rotor As the slide valve travels axially from the full load position it uncovers a port which vents part of the gas trapped in the main rotor flute back to suction before compression can begin When the flute has pas
