Description
Technical field
The utility model relates to air-conditioning technical field, more specifically, relates to a kind of compressor of air-conditioning system and has the air-conditioning system of this compressor.
Background technique
R22 refrigeration agent is classified as by " Montreal is discussed and decided " book the refrigeration agent that time limit progressively eliminates.Europe, Japan start to turn to R410A refrigerant replacement already, and the U.S. also starts to forbid the use of R22 in new refrigeration product.China also accelerates the paces that R22 eliminates, and within 2015, will reach the requirement of 10% of reduction baseline values.And more domestic major brand also start to release the environment-friendly air conditioner of R410A as refrigeration agent.But the GWP value of R410A is also larger than R22, R410A has been classified as the greenhouse gases of controlled discharge by " Kyoto Protocol ", and all R410A are never long-range replacement schemes.
The R32 of one of refrigeration agent, i.e. difluoromethane as an alternative, for industry is paid close attention to.Its GWP is 675, is only about 1/3rd of R410A (GWP2100).Its safety class is A2L, flammable well below carbon-hydrogen refrigerant R290.Therefore, the product of application R32 refrigeration agent, in marketing and in the acceptance level of market, is better than R290 refrigerant product.But when the refrigeration agent used in air-conditioning changes, the structure of air-conditioning also should adjust.
Model utility content
The application makes the discovery of the following fact and problem and understanding based on model utility people:
Model utility people tests using the air-conditioning system of R32 refrigeration agent, find under air-conditioning ASHRAE test condition, no matter compressor is in suction condition or exhaust condition, adopt R32 refrigeration agent more much lower than the mass flow rate of R410A refrigeration agent, be about 65% ~ 75% of R410A refrigeration agent, specifically as shown in table 1:
Table 1
As for latent heat of vaporization aspect, at 40 DEG C and 10 DEG C, R32 refrigeration agent then exceeds about 20% than R410A refrigeration agent, specifically as shown in table 2.
Table 2
Because the latent heat of vaporization is higher, unit mass refrigerant suction or liberated heat more, therefore, although the R32 refrigeration agent shown in table 1 is more much lower than the mass flow rate of R410A refrigeration agent.But, under air-conditioning ASHRAE test condition, when compressor adopts identical discharge volume, adopt R32 refrigeration agent still can exceed about 5% ~ 7% than the refrigerating capacity of R410A refrigeration agent, specifically as shown in table 3.
Table 3
Therefore, obtain identical refrigerating capacity, the discharge volume of the compressor with rolling rotor of employing R32 refrigeration agent can than smaller during employing R410A refrigeration agent.

In view of this, the model utility people of the application is specially for adopting the air-conditioning system of R32 refrigeration agent to be studied, wherein improve the structure of compressor especially, make the compressor after improvement and air-conditioning system thereof can mate R32 refrigeration agent, usability is better.
Specifically, the lubricant oil of compressor inside has clearance seal, moving surface to lubricate and takes away the effect of heat.Model utility people finds, how the enclosed volume (i.e. oil sealing amount) of the lubricant oil of compressor inside can affect the smoothness of compressor air-discharging, causes power to rise, while also can make too much lube oil retention in heat exchanger, heat exchange efficiency is worsened; The enclosed volume of lubricant oil, and to have lacked the fuel delivery that then can make compressor shaft portion not enough, simultaneously also can dilute by relatively too much refrigeration agent, cause greasy property to worsen.
Therefore, when the filling quantity of refrigerant of the internal structure of compressor, discharge capacity, air-conditioning system changes, the enclosed volume of lubricant oil also needs to adjust.The oil sealing amount of model utility people to the compressor adopting R32 of the application has carried out special design, and make the greasy property of the compressor of employing R32 good, lower power consumption, working efficiency promotes.
The utility model is intended to solve one of technical problem in correlation technique at least to a certain extent.For this reason, the utility model proposes a kind of compressor of air-conditioning system, the greasy property of described compressor lubrication is good, and working efficiency improves, safe and reliable.
The utility model also proposed a kind of air-conditioning system with above-mentioned compressor.
