Hefei Which do small air heat pump hot water system project

Hefei Which do small air heat pump hot water system project air heater during use, often encounter some problems, after a detailed analysis of both the appropriate solutions. A compressor oil loss? Analysis of reasons: 1, 2 suction pressure is too low, the refrigerant circuit blockage 3, thermal expansion valve opening too Solution: 1, to improve the evaporator side load, check the suction pipe valve clogging 2, leak detection, add refrigerant 3 Clean or replace the thermostatic expansion valve Second, large compressor noise? Analysis of reasons: 1, the oil pressure is too low 3, muffler, intake and exhaust valve bad or broken 2, within the piping, valves fastening portion loose, vibration 3, thermal expansion valve opening is too large Remedy: 1. Replace lubricants, muffler, intake and exhaust valves 2, check the tightening of the compressor, piping, valves 3, adjust the thermal expansion valve opening of three compressor downtime? Cause: 1, sensing probe resistance not broken off or sensing line 2, the thermostat position become misplaced or malfunction solution: 1, replace the sensing probe 2, relocating the repair or replacement of the thermostat four, running But the difference between normal heating capacity? Analysis of reasons: 1, the compressor discharge valve, thermostatic expansion valve damage 2, air and other non-condensable gas refrigerant in the system or systems lack 3, defrost controller, time relay failure 4, 5 in the solenoid valve leak hydrophilic aluminum are clogged with dust Solution: 1. Replace or repair or readjust the opening degree 2, add refrigerant leak or replace the desiccant, refrigerant, the solenoid valve (3), scrub with a brush and tap V. compressor frosting? Analysis of reasons: 1, the thermal expansion valve failure or excessive opening 2, the thermal expansion valve bulb off 3, thermal expansion valve spool stuck or improper temperature settings 4, the refrigerant charge is insufficient Solution: 1, adjusting, cleaning Replace thermostatic expansion valve 2, re dressing thermal package 3, readjust 4, leak detection, trap, charging refrigerant Hefei Which do small air heat pump hot water system project company
