Description
Technical field
The utility model belongs to the air-conditioning equipment field, particularly relates to a kind of single cold type helical-lobe compressor and joins central air conditioning plant more.
Background technology
The central air-conditioning that join rely on its technical advantage more, the application scenario more and more widely, like occasions such as apartment, villa, bank, food and drink, KTV, commercial office complex, station, markets.Along with the continuous expansion of many couplet central air-conditioning application, the area of now large-scale station, market, food processing shop etc. reaches several ten thousand square meters.Yet the compressor major part of many couplet central air-conditioning of prior art is a scroll compressor, and some is a helical-lobe compressor.
But the former receives the restriction of single cover scroll compressor power; Every cover scroll compressor peak power has only 64HP, for large-scale occasion, makes up with regard to needing large quantities of scroll compressors; So the floor space of off-premises station is very big, some occasion even can't all off-premises stations be put down; Scroll compressor is many more on the other hand, and the pressure of the oily balance reliability between the compressor is just big more, and the security of lubricating oil operation is just poor more.
And the latter to be the helical-lobe compressor of pump type heat join central air-conditioning more, be applicable to summer indoor room need refrigeration, the indoor room large-scale application scenario that need heat in the winter time; But in occasion, no matter be in the winter time, still in summer such as golf calorific values such as food processing shop, film production workshops; The workshop all produces these occasions of great amount of heat; It is idle to cause heating mode to occur, so use cost is higher, has also strengthened user's initial investment.
The utility model content
The utility model to above problem provide that a kind of off-premises station peak power is big, the off-premises station floor space is less, the lubricating oil safety in operation better, use cost is low and the less single cold type helical-lobe compressor of user's initial investment joins central air conditioning plant more.
The utility model overcomes the above problems used technical scheme: provide a kind of single cold type helical-lobe compressor with following structure to join central air conditioning plant more; It comprises indoor set, reservoir, condenser, gas-liquid separator, gs-oil separator, muffler and the main feed pipe of at least one helical-lobe compressor, many parallel connections; Described helical-lobe compressor is provided with exhaust outlet, mouth spray and air entry; Described exhaust outlet is provided with the blast pipe that is communicated with the gs-oil separator import; The outlet of described gs-oil separator is communicated with the import of condenser; The outlet of described condenser is communicated with reservoir, and described reservoir is communicated with the indoor set import of many parallel connections through main feed pipe, and described main feed pipe is communicated with mouth spray simultaneously; The indoor set outlet of described many parallel connections is communicated with the import of gas-liquid separator, and the outlet cooled via return air pipe of described gas-liquid separator is communicated with air entry; Said connection all is meant through pipeline and is communicated with.
After adopting above structure, compared with prior art, the utility model is owing to adopt helical-lobe compressor; And the power of screw compressor is bigger, and peak power can reach nearly 400HP, is far longer than the peak power 64HP of conventional scroll compressor; So the required less demand that just can satisfy indoor set of number of compressors, floor space is also just less, and oily balance is better between the compressor; The security of lubricating oil operation is just good more, and cost is also relatively low; And join central air conditioning plant with the pump type heat helical-lobe compressor more and compare; Only has refrigerating capacity; But save magnetic valve, four-way change-over valve that main four-way change-over valve, hot-gas bypass be associated, heated orifice union and the parts such as check valve parallelly connected with orifice union; So use cost is lower, user's initial investment is less.Therefore the utlity model has that the off-premises station peak power is big, the off-premises station floor space is less, the lubricating oil safety in operation better, use cost is low and user's initial investment features of smaller.
As improvement, the bottom of described gs-oil separator is provided with oil return opening, and described oil return opening is communicated with through pipeline with air entry; And the pipeline between oil return opening and the air entry is provided with oil return solenoid valve; Then the oil of gs-oil separator bottom accumulation will add in the helical-lobe compressor through pipeline, and the oil subsidy that the setting of oil return solenoid valve makes air conditioning control device can control at any time the accumulation of gs-oil separator bottom again is charged in the helical-lobe compressor, to prevent the helical-lobe compressor oil starvation; And the phenomenon that burns out takes place; And also can when not needing repairing, close pipeline, oil leakage phenomenon too much occur to prevent lubricating oil.
As further improvement; The bottom of described gas-liquid separator is provided with oil-out; Described oil-out is communicated with through pipeline with muffler, and the pipeline between oil-out and the muffler is provided with out solenoid, when the repairing that then can't satisfy helical-lobe compressor when the oil in the gs-oil separator requires; Can be charged in the helical-lobe compressor through going out the oil subsidy that solenoid gathers gas-liquid separator bottom, so the safety in operation of lubricating oil is better.
As further improving again; Be communicated with through pipeline between described blast pipe and the muffler; And this pipeline is provided with the unloading magnetic valve; When then if aircondition is in an emergency, open the unloading magnetic valve and directly the high-temperature high-pressure refrigerant in the blast pipe is discharged in the muffler, can guarantee the security of aircondition operation effectively.
As further improving again; Described helical-lobe compressor is three; Also be provided with oil heater, oily balance pipe and oil level visor on the described helical-lobe compressor, and be provided with the connection of balance oil pipe between the oily balance pipe of each helical-lobe compressor, then the lubricating oil balance in each helical-lobe compressor is better; Prevent helical-lobe compressor because of lacking lubricating oil, and cause situation about burning out; Oil heater can be evaporated the cold-producing medium that dissolves in the lubricating oil, prevents cold-producing medium along with lubricating oil gets into compression chamber, and the phenomenon that liquid hammer causes the compressor infringement takes place, so the security of the lubricating oil of the utility model operation is better.
As further improving, be equipped with stop valve on the pipeline that is communicated with between described each parts, then when maintenance, only need corresponding two ends, fault place ball valve is closed, can repair or replace components and parts, make that the maintenance of the utility model is convenient.
The pipeline of described mouth spray is provided with heating power expansion valve and hydrojet magnetic valve.
