Abstract
The utility model relates to an outdoor conditioner of on-line air-conditioning system which comprises at least one outdoor conditioner module unit, wherein each outdoor conditioner module unit comprises a low-pressure liquid tank (1), a compressor (2), a four-port valve (3) and a condenser (4), further more, each outdoor conditioner module unit comprises a solenoid valve (SV), one end of the SV is connected with the condenser (4), the other end of the SV is connected with the liquid tank (1). The configuration that one end of the SV is connected with the condenser, the other end of the SV is connected with the liquid tank. In the utility model, when defrosting and cold heat-starting, the SV is turned on when system low pressure is over-low to supplement low pressure, the low pressure does not increase high and the compressor is protected effectively, further more, the cold media forms a refrigeration cycle of short course, thereby reduces the defrosting time and reaches the aim of quickly defrosting.
Description
Technical field
The utility model is a kind of multi-online air-conditioning system off-premises station, particularly a kind of long multi-online air-conditioning system off-premises station of multimode pipe arrangement that is suitable for.
Background technology
Traditional multi-online air-conditioning system heating and defrosting is that evaporimeter and condenser are changed by cross valve commutation, carries out kind of refrigeration cycle and reaches the defrost purpose.But when evaporimeter and the conversion of condenser high-low pressure, cold-producing medium is difficult to set up rapidly metastable motion state, and have a large amount of liquid refrigerants to pour in low-pressure liquid storing tank, particularly for multimode and the long system of pipe arrangement, piping length reaches 175m sometimes, circulating mass of refrigerant is big, low-pressure liquid storing tank can accumulate a large amount of liquid refrigerants during defrosting, causes pressure of inspiration(Pi) lower, and pressure ratio is bigger, compressor is worked the mischief, and defrosting time is longer.Equally, in the low-temperature heating start-up course, because pipe arrangement is long, refrigerant circulation is big, liquid refrigerants evaporation capacity at short notice is limited, is difficult to satisfy the inspiratory capacity of compressor, the low excessively situation of low pressure also can occur.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of low pressure of can replenishing is provided; make pressure ratio not too large; effectively protect compressor and can shorten defrosting time, guarantee the multi-online air-conditioning system off-premises station of complete machine energy safe and stable operation under various operating modes.
Structural representation of the present utility model as shown in the figure, comprise an above off-premises station modular unit, each off-premises station modular unit comprises low-pressure liquid storing tank (1), compressor (2), cross valve (3) and condenser (4), wherein each off-premises station modular unit also comprises magnetic valve (SV), magnetic valve (SV) termination condenser (4), another termination low-pressure liquid storing tank (1).
The utility model is because the magnetic valve one termination condenser in each off-premises station modular unit; another termination low-pressure liquid storing tank; when defrosting and low-temperature heating startup, when the system low-voltage hypotony, open magnetic valve, so just can replenish low pressure; make pressure ratio not too large; effectively protected compressor, in addition, because refrigerant can form the short kind of refrigeration cycle of a distance by magnetic valve; so just shorten the time of defrost, reached the purpose of quick defrost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
