Semi-hermetic two-stage compressor

Usability:

•The same serial compressors are available for many kinds of refrigerants such as R134a, R404a, R407C and R22

•The same serial compressors are suitable for different operating temperatures.

Products Description Message

Excellent functions:

•High efficiency motors.

•Great gap control, high quality and low energy consumption in order to achieve a higher refrigerating capacity.

•Great mass balance of driving parts, less vibration and lower noise.

Special design for the construction:

•BFBV20 56H(Y) applies coil motor with low starting current.

•The materials which can reduce the friction are used.

•The valves are constructed with buffer activation.

Reliability protector:

•Electronic module protector is installed in the motor to control its operating temperature.

•BFBV20 84.5(Y) use oil pump for a good lubrication system.

•BFBV20 56H(Y) is equipped with auto protector of high pressure release valve.

•Crankcase heater is applied for preventing liquid strike.

Vapor temperature(R22)	+ 12.5℃〜-25℃ (-30℃)	-5℃ ～-30℃ (-40℃)
Cooler temperature(R22)	30℃ ~ 55℃
Suction temperature	Max. 20℃
Max. compression ratio	15
Max. working pressure	High pressure side 2.5MPa
Max. differential pressure	1.8MPa
Max. outlet air temperature	130℃ (the temperature of the exterior of the exhaust pipe 150mm away from the exhaust valve.)
Degree of overheating of inlet air	Least. 10k;Max.Promise not to exceed the highest exhaust temperature
Moter power	380V/3N ~/50Hz; 440V/3N ~/60Hz
Motor insulation level	Grade F
Allowance in voltage	Rated voltage ±10%
Unbalanced two-phase current	10%
Unbalanced two-phase voltage	2%
Max. start-up times per hour	6 times
Max. oil temperature of crankshaft box	80℃
High ambient temperature	43℃

Note：

1. For many reasons the running conditions of the compressor should be strictly limited to accord with the above-mentioned specifications.

2.If the vaporization temperature is between -15℃ to -30℃, a cooling fan should be fixed at the cylinder end. Air-cooled condenser flow needs no cooling fan.

3.If the vaporization temperature is between -20℃ to -40℃, cooling fan and cooling spray system should be fixed at the cylinder end.
