Background technology
Central air-conditioning unit when operation, be subjected to load condition change violent, compressor load changes and the impact of the factors such as physical characteristic of compressor and freeze oil, compressor tends to intermittently suck liquid refrigerant in evaporimeter, causes liquid hammer.Secondly, the at high temperature charing of compressor and freeze oil can cause that compressor lubrication lost efficacy and finally caused compressor damage.
For this reason, part pump type heat central air-conditioning unit need configure oil cooler and gas-liquid separator simultaneously, thereby has increased the equipment configuration of whole central air-conditioning unit, makes system pipeline complicated, and makes troubles to air-conditioning unit structure design and project installation.
Summary of the invention
The purpose of this invention is to provide a kind of high efficient oil cooling device with gas-liquid separation; it has the problem that can solve pump type heat unit refrigeration oil excess Temperature and compressor Wet Compression; thereby realize the unification of gas-liquid separator and oil cooler; and then simplify the unit equipment configuration, guarantee unit safety, the characteristics of moving efficiently.
The technical solution adopted in the present invention is: with the high efficient oil cooling device of gas-liquid separation, comprise oil inlet pipe, refrigerant inlet pipe, refrigerant outlet pipe, flowline and heat exchanger tube, and the two ends of this heat exchanger tube connect respectively oil inlet pipe and flowline, the outer wrap of described heat exchanger tube has housing, and this oil inlet pipe and flowline all stretch out in the outside of this housing, simultaneously, this refrigerant inlet pipe and refrigerant outlet pipe are communicated with this housing, and the bottom of this housing is provided with the liquid collecting bag, and this liquid collecting is wrapped and is provided with oil return pipe.
Described heat exchanger tube is close to the position of bottom liquid collecting bag.
The advantage that compared to the prior art the present invention has is:
1, the high efficient oil cooling device with gas-liquid separation of the present invention integrates gas-liquid separator and oil cooler, has reduced the unit equipment configuration, has reduced product cost, and set structure is compact, facilitates field engineering to install.
2, the high efficient oil cooling device with gas-liquid separation of the present invention utilizes the cold-producing medium of evaporator outlet to collide gas-liquid separation and deadweight gas-liquid separation, and the heat of disadvantageous compressor high temperature refrigeration oil is passed to cold-producing medium, strengthen the cold-producing medium endothermic gasification, thereby can reduce the outlet degree of superheat of evaporimeter, also can effectively avoid the compressor Wet Compression, improve evaporation and heat-exchange efficient and the complete machine Energy Efficiency Ratio of evaporimeter.
3, with respect to the traditional oils cooler that adopts water-cooling pattern, high efficient oil cooling device with gas-liquid separation of the present invention can utilize low-temperature refrigerant to come the cooling down high-temperature refrigeration oil, oil cooler be need not separately to establish the equipment such as water pump, cooling water pipeline and valve, simplified system pipeline.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the front view (broken section) of embodiments of the invention;
Fig. 2 is the left view of Fig. 1.
In figure: 1, oil inlet pipe; 2, heat exchanger tube; 3, housing; 4, refrigerant inlet pipe; 5, refrigerant outlet pipe; 6, flowline; 7, liquid collecting bag; 8, oil return pipe.
The specific embodiment
Embodiment sees illustrated in figures 1 and 2: with the high efficient oil cooling device of gas-liquid separation, comprise oil inlet pipe 1, refrigerant inlet pipe 4, refrigerant outlet pipe 5, flowline 6 and heat exchanger tube 2, and the two ends of this heat exchanger tube 2 connect respectively oil inlet pipe 1 and flowline 6.Concrete, this high efficient oil cooling device with gas-liquid separation also comprises the airtight housing 3 that is wrapped in this heat exchanger tube 2 outsides, and this oil inlet pipe 1 and flowline 6 all stretch out in the outside of this housing 3.Certainly, this oil inlet pipe 1 and flowline 6 all carry out good sealing with the joint portion of this housing 3.Simultaneously, this refrigerant inlet pipe 4 and refrigerant outlet pipe 5 is communicated with these housings 3, and the bottom of this housing 3 is provided with liquid collecting bag 7, and this liquid collecting bag 7 is provided with oil return pipe 8.Certainly, this oil return pipe 8 can be connected to compressor.
Obviously, above-described oil inlet pipe 1 and flowline 6 are respectively used to pass into and discharge refrigeration oil; Described refrigerant inlet pipe 4 and refrigerant outlet pipe 5 are respectively used to pass into and discharging refrigerant.
Like this, the circulation process of refrigeration oil is: the compressor and freeze oil of high temperature through oil inlet pipe 1 enter heat exchanger tube 2 and with housing 3 in cold-producing medium heat exchange cooling, get back to compressor by flowline 6 after reaching the required temperature of compressor and viscosity.
The refrigerant circulation flow process is: cold-producing medium enters housing 3 by refrigerant inlet pipe 4 and at first collides separation, impel the deposition of large diameter liquid refrigerant and oil droplet, gas enters compressor by refrigerant outlet pipe 5 and compresses, and the liquid refrigerant that separates carries out the heat exchange gasification with the high temperature refrigeration oil.
Simultaneously, the high temperature refrigeration oil makes cold-producing medium be vaporized separation when being cooled, and has realized the integrated of gas-liquid separator and oil cooler.
Wherein, this liquid collecting bag 7 is used for storing separated a small amount of liquid refrigerant and the refrigeration oil that gets off.That is, this liquid refrigerant constantly absorbs the heat of high temperature refrigeration oil and gasifies, and the refrigeration oil concentration in liquid collecting bag 7 can be more and more higher, and can return to the refrigeration oil in liquid collecting bag 7 to compressor by phased manner this moment by oil return pipe 8.
Optimize, this heat exchanger tube 2 is close to the position of bottom liquid collecting bag 7.Such as the distance between, these heat exchanger tube 2 bottoms and liquid collecting bag 7 tops is not more than 10mm.Like this, make the abundant endothermic gasification of a small amount of liquid refrigerant energy in liquid collecting bag 7, the refrigeration oil of avoiding returning to compressor is carried liquid refrigerant secretly.
The above is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
