5.10. A design of a refrigerator path of a central air of air
The refrigerator path of a central air has the standard organisation.
The scheme of the organisation of a refrigerator path of a central air of air
After an exit from the compressor the coolant is banished through the condenser, the dehumidifier arrives in a receiver/, is pumped over through the evaporator and comes back back in the compressor. Process of transition of a coolant in a gaseous state is supervised from the outside by means of the evaporator of the broad valve built in assemblage.
Protection of system against excessive fall / of increase of pressure is carried out by means of the gauge-switch built in in a receiver, — as soon as pressure in system falls outside the limits an admissible range (upwards or downwards), the gauge-switch is disconnected, stopping compressor functioning.
Besides, the safety valve which is carrying out emergency dump of surpluses of a coolant in atmosphere at excess by pressure in a path of value at 3.73 кПа is built in a back part of the compressor .
