The first figure is the model number JT160BCBBY1L, is Daikin's 5HP compressor, the number 160 * 100 = 16000w refers to the nominal refrigeration capacity, the equivalent of 5HP. source is the power supply used, can be used for 50, 60HZ380V power supplyref is the refrigerant R22refoil is the refrigerant corresponding refrigeration oil NO is the production number DP-AP is the required high and low pressure. Refrigerant corresponding to the refrigeration oil NO is the production number DP-AP is the requirement of high-pressure and low-pressure the second picture is not very clear.
JM521 is the compressor model below is the use of power, refrigerant, high and low voltage requirements, production date and number of the general nameplate is not labeled power and rated current will be labeled blocking current, maximum load current (external current protector).
Air compressor
is a device used to compress gas. Air compressor and pump construction is similar. Most air compressors are reciprocating piston, rotary vane or rotary screw. Centrifugal compressors are very large applications.
