Description
Technical field
The utility model belongs to air conditioner refrigerating energy-conserving and emission-cutting technology field, relates to a kind of cold-producing medium filling mechanism, especially relates to a kind of cold-producing medium for random air-conditioning refrigeration system filling energy-saving mechanism.
Background technology
Existing do not have filling opening with air conditioner when dispatching from the factory, and this just makes when needing to keep in repair at ordinary times, the copper pipe with air conditioner must be cut open, and first the cold-producing medium of the inside bled off, then weld a maintenance joint on copper pipe; After to be repaired, filling cold-producing medium, then copper pipe is closed; But when needing next time again to keep in repair, must repeat above-mentioned treatment step again, this not only wastes time and energy, and be easy to the leakage causing random air-conditioning refrigeration system, so that affect it and normally use.Meanwhile, in normal use procedure, if not good with the refrigeration of air conditioner, owing to not arranging filling opening, also cannot add cold-producing medium, equally, original cold-producing medium is also inconvenient to reclaim, and this brings great inconvenience all to the normal use with air conditioner.
Summary of the invention
The purpose of this utility model is exactly provide a kind of structure simple to overcome defect that above-mentioned prior art exists, economical and practical, the safe and reliable filling of the cold-producing medium for random air-conditioning refrigeration system mechanism.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of filling of the cold-producing medium for random air-conditioning refrigeration system energy-saving mechanism, described refrigeration system comprises condenser, filter, flow controller, evaporimeter, gas-liquid separator and compressor, described condenser one end connects filter successively by pipeline, flow controller, evaporimeter, gas-liquid separator and compressor, and the other end being connected to condenser is returned by compressor, form circularly cooling circuit, described filling mechanism is arranged between gas-liquid separator and compressor, and described filling mechanism comprises liquid-feeding tube, be arranged on the control valve on liquid-feeding tube and liquid feeding table.
Pipeline between described gas-liquid separator and compressor offers the filling opening suitable with liquid-feeding tube.
Described liquid-feeding tube one end is provided with interface conversion head, and is connected with described filling opening by interface conversion head, and the other end is provided with control valve, and by control valve and liquid feeding list catenation.
Described control valve is ejector pin valve.
Described liquid-feeding tube is high-pressure rubber pipe.
The utility model filling mechanism is arranged between gas-liquid separator and compressor, when needing to carry out maintenance and inspection at ordinary times, open control valve, released with the cold-producing medium in air conditioner by liquid-feeding tube, and after reclaiming, carry out maintenance and inspection again, after to be repaired, in the refrigeration system new cold-producing medium is injected into air conditioner through liquid-feeding tube by control valve, in the process, the addition of cold-producing medium can also be regulated by liquid feeding table, prevent cold-producing medium excessive, thus working strength can be greatly reduced, and shorten maintenance time.
Compared with prior art, the utility model has following characteristics:
1) owing to being provided with interface conversion head in liquid-feeding tube one end, in use, different interface conversion heads can be changed according to actual conditions, may be used for the random air-conditioning refrigeration system of different size like this, applied widely;
2) owing to adopting liquid feeding table, the convenient actual addition controlling cold-producing medium, avoids the too much or very few, simple and practical of cold-producing medium;
3) because liquid-feeding tube is high-pressure rubber pipe, be conducive to the security and the air-tightness that ensure whole mechanism, effectively avoid leaking, and in not used time, liquid-feeding tube can be received in random air conditioner casing, effectively save space;
4) structure is simple, and economical and practical, cost is low, safety durable, effectively can improve the maintenance efficiency with air conditioner, is conducive to reducing energy consumption, is convenient for changing cold-producing medium.
