Abstract
The invention discloses a processing method for compressor faults of some outdoor units of a multi-coupled air conditioner during a heating process. The processing method comprises the following steps: using a connecting pipeline (2) with a ball valve (1) for connecting an outlet of an outdoor heat exchanger (3) of each outdoor unit with the outlet of the outdoor heat exchanger (3) of an adjacent outdoor unit; normally running each outdoor unit under a heating mode; opening the ball valve (1) of the connecting pipeline (2) between a fault outdoor unit and an adjacent normal outdoor unit after a compressor (4) of one outdoor unit is in fault and cannot normally work. According to the processing method, a specially-assigned person does not need to repair on-site and the self-regulation of the machine unit can be utilized to quickly and efficiently solve the problem of insufficient heat exchange amount caused by the faults of part of compressors.
Description
Technical field
The present invention relates to VRF Air Conditioning System, be called for short combined air conditioners, the processing method of the compressor fault of the part off-premises station of combined air conditioners while being specifically a kind of heating.
Background technology
The VRF Air Conditioning System of prior art comprises multiple off-premises stations parallel with one another, multiple indoor set parallel with one another and connects two refrigerant circulation house stewards of each indoor set and off-premises station.Multiple off-premises stations after parallel connection are communicated with the multiple indoor sets after parallel connection by two refrigerant circulation house stewards.
Each off-premises station comprises compressor, oil eliminator, four-way change-over valve, outdoor heat exchanger (being evaporimeter when heating mode), outer organic electronic expansion valve and gas-liquid separator.Compressor outlet is communicated with one end of oil eliminator, the other end of oil eliminator is communicated with the first valve port of four-way change-over valve, the 3rd valve port of four-way change-over valve is communicated with a refrigerant circulation house steward in two refrigerant circulation house stewards, another root refrigerant circulation house steward in two refrigerant circulation house stewards is communicated with one end of outer organic electronic expansion valve, the other end of outer organic electronic expansion valve is communicated with one end of outdoor heat exchanger, the other end of outdoor heat exchanger is communicated with the second valve port of four-way change-over valve, the 4th valve port of four-way change-over valve is connected with one end of gas-liquid separator, the other end of gas-liquid separator is communicated with suction port of compressor.When heating mode, the first valve port of four-way change-over valve is communicated with the 3rd valve port, the second valve port is communicated with the 4th valve port, and refrigerant is along compressor, indoor heat exchanger, interior organic electronic expansion valve, outer organic electronic expansion valve, outdoor heat exchanger, this route circulation of compressor.
Each indoor set comprises interior organic electronic expansion valve and indoor heat exchanger (being condenser when heating mode), one end of indoor heat exchanger is communicated with one end of interior organic electronic expansion valve, the other end of interior organic electronic expansion valve is communicated with in two root refrigerants circulation house stewards one, and the house steward that circulates is communicated with for the other end of indoor heat exchanger and another root refrigerant in two root refrigerants circulation house stewards.
This air-conditioning unit is in actual motion, part is that the compressor of one or more off-premises station may break down, once the compressor fault of certain off-premises station, the outdoor heat exchanger of this off-premises station also cannot carry out heat exchange naturally, cause the heat exchange area of unit to reduce, heat exchange quantity not sufficient, can not meet the needs that user heats.At this time, can only rely on the special on-site maintenance of professional maintenance personal just may solve fault, and even if special messenger's on-site maintenance, the fault of compressor also likely be can not repair in short-term, like this, the speed of solution fault is slow, consuming time for a long time, efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of only rely on without special messenger's on-site maintenance unit self-regulation just can be fast, the efficient processing method of the compressor fault of the part off-premises station of combined air conditioners while solving the heating of problem that causes heat exchange quantity not sufficient due to Partial shrinkage machine fault.
Technical solution of the present invention is, the processing method of the compressor fault of the part off-premises station of combined air conditioners when a kind of heating is provided, and its concrete steps are as follows:
A, the outlet of the outdoor heat exchanger of the outlet of the outdoor heat exchanger of each off-premises station and an off-premises station adjacent with this off-premises station is connected with connecting line with ball valve;
B, under heating mode, normally move each off-premises station, once after the compressor of some off-premises stations breaks down and cannot normally work, open the ball valve of the connecting line between fault off-premises station and an adjacent normal off-premises station;
C, refrigerant is after the indoor heat exchanger heat exchange of each indoor set, enter same refrigerant circulation house steward, be further divided into two strands of refrigerants, outer organic electronic expansion valve and the outdoor heat exchanger of one normal off-premises station of still flowing through, the outer organic electronic expansion valve of another stock-traders' know-how fault off-premises station, outdoor heat exchanger and connecting line flow to the outlet of the outdoor heat exchanger of normal off-premises station, two strands of refrigerants are also all inhaled into the compressor of normal off-premises station at the interflow, outdoor heat exchanger exit position of normal off-premises station, then discharged by compressor, enter another root refrigerant circulation house steward through the oil eliminator of normal off-premises station, finally reenter each indoor set, complete circulation.
Adopt above method, when the present invention heats, the processing method of the compressor fault of the part off-premises station of combined air conditioners compared with prior art, has the following advantages:
The outdoor heat exchanger of the off-premises station breaking down, its heat exchange area was idle cannot utilization originally, but pass through the method, utilize connecting line, make in fact the outdoor heat exchanger of fault off-premises station in parallel with the outdoor heat exchanger of normal off-premises station, like this, the compressor of normal off-premises station can drive refrigerant this two outdoor heat exchangers of flowing through simultaneously, before the compressor of fault is not fixed at all, just rationally utilize originally due to the unserviceable outdoor heat exchanger of compressor fault, avoid the idle of this outdoor heat exchanger, enough heat exchange areas are ensured, overcome because compressor fault causes set heat exchange area and reduced, the drawback of heat exchange quantity not sufficient.And the method is without the good compressor of special messenger's on-site maintenance by the time, but only rely on unit self-regulation completely, just can ensure enough heat exchange amounts, the speed of dealing with problems is fast, consuming time short, efficiency is high.
