   The operational characteristics of the compressor is the compressor running in the range of operating conditions within the design requirements, compressor cooling cap acity and input power corresponding with the evaporating temperature and condensing temperature (ie, corresponding to the suction pressure and exhaust pressure) change relations, the general curves and tables, to provide air conditioning vents machine manufacturers used.
    In general, when a certain evaporating temperature, condensing temperature rise, the refrigeration compressor power consumption increases; certain condensing temperature, evaporating temperature dropped, the cooling capacity significantly decreases. This is because the evaporation temperature drop corresponding to the suction pressure, compressor suction gas volume increases (density decreases), the quality of the suction compressor gas decline, causing the decline of cooling capacity. When the evaporation temperature is constant, with the rise in condensing temperature, compressor discharge pressure increase s,ball spout the gas compressor quality decline moderate, causing compression power increases, causing the compressor power consumption increases. In addition, with the discharge and suction pressure ratio (pressure ratio) increases, the compressor discharge temperature will cause the compressor to overheat the compressor lubrication deterioration in the terms of the compressor motor temperature increased, the quality of gas transmission capacity. cooling capacity decreased, and in severe, causing the compressor to \"bite the cylinder, the motor burned.
