| 7.14 System characteristics | The flow of the refrigeration system is automatically switched
under different working conditions, and the excess system is cut
off for energy-saving operation - Cooling control: multi-stage evaporator combination can obtain more
uniform and efficient cooling exchange efficiency and refrigeration
output; flow control is automatically adjusted by their matching
electronic expansion valves;
The 2) control system automatically adjusts the optimal energy
saving condition of refrigerant operation according to test
conditions; condensate pressure regulating valve (cooling water
flow regulating device), evaporative pressure regulating valve
(prevent evaporator freezing), and compressor return cooling
circuit. The controller digital displays the high, low pressure,
exhaust temperature and operating current of the compressor of the
refrigeration system 3) Refrigeration process: the protection measures for the
compressor are fully considered in the design of the refrigeration
system, such as the automatic compressor suction and exhaust
pressure protection function, which keeps the compressor to
maintain the operating temperature within the normal temperature
range, to avoid the compressor too cold or overheating, so as to
prolong the service life of the compressor. High-quality anaerobic
copper pipe gas protection welding method is adopted, which avoids
the damage of oxides on the inner wall of the copper pipe to the
refrigeration system and the compressor. In the design of the
refrigeration system, the vibration reduction measures of the unit
operation, such as the compressor installing spring shock absorber,
and adopting the way of increasing arc bending on the refrigeration
pipeline to avoid pipeline deformation and leakage caused by
operation vibration and temperature changes, thus improving the
reliability of the whole refrigeration system. Other energy saving measures: the following effective energy
regulation measures are adopted, such as refrigeration volume
regulation, gas-liquid bypass regulation, evaporation temperature
regulation, etc. At any low temperature point, the operation power
can be reduced to half, reducing the operation cost and failure
rate of the cooling system to a relatively economic state. 5) compressor air return temperature regulation: automatically
adjust the air return temperature of the compressor to keep the
compressor temperature within the normal range and avoid over-cold
and overheating of the compressor. 6) vibration reduction measures: 1. Compressor: spring vibration
damping.2. Refrigeration system: special rubber pad overall
secondary vibration damping; the refrigeration system pipeline adds
R and elbow to avoid the variation of the copper pipe caused by
vibration and temperature changes, thus causing the rupture of the
refrigeration system pipeline. 7) noise reduction: refrigeration cabinet: wavy special acoustic
sponge. |
