Description of drawings
Fig. 1 be in one embodiment of the invention different R290 refrigeration agent enclosed volumes to the figure that influences of air conditioner refrigerating capacity.
Fig. 2 is the influence figures of different R290 refrigeration agent enclosed volumes to the air conditioner efficiency.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Because carbon-hydrogen refrigerants such as propane R290 or propylene R1270 are 0 to the rupture factor of ozonosphere, global warming coefficient GWP value is very low, so can ignore basically, is long-range substitute.Yet; According to American National Standard/U.S. heating refrigerating conditioner engineering Shi Xuehui standard A NSI/ASHRAE 34 " refrigeration agent method for numbering serial and Security classification "; The Security classification of carbon-hydrogen refrigerants such as propane R290 and propylene R1270; Be defined as A3 level refrigeration agent, be hypotoxicity, high combustible refrigerant.
In the world, in order to promote the application of flammable carbon-hydrogen refrigerant better, put into effect the Secure Application that the associated safety rules remove to instruct carbon-hydrogen refrigerant, for example IEC 60335-2-40 (2005) standard, and BS EN 378 (2008) standards.Its reason is, if when the concentration of the flammable carbon-hydrogen refrigerant that is contained in the room has reached the minimum limit of inflammability LFL of carbon-hydrogen refrigerant itself, in a single day it meet incendiary source, will burn!
More than two parts of standards, in the room to different spaces size, use the upper limit of carbon-hydrogen refrigerant enclosed volume of the air-conditioning system of flammable carbon-hydrogen refrigerant, limit.The restriction regulation of these two parts of standards is all identical.Even if make the flammable carbon-hydrogen refrigerant in the air-conditioning system all leak in the room, do not reach the minimum limit of inflammability of carbon-hydrogen refrigerant itself yet, and the danger that can not burn.And this carbon-hydrogen refrigerant to allow maximum enclosed volume be such regulation:
m
Max=2.5 * (LFL)
(5/4)* h
0* (A
) 1/2Formula one,
In formula one: m
MaxFor the carbon-hydrogen refrigerant of equipment allows maximum enclosed volume,
A is a room area,
LFL: minimum limit of inflammability,
h
0: the equipment setting height(from bottom);
Draw thus, use the air conditioner of propane R290 refrigeration agent, when in the room of different area, using, the maximum refrigeration agent enclosed volume such as the following table one of air conditioner.
Table one
In order to satisfy this refrigeration agent enclosed volume regulation.Must take some measures, for example reduce the cavity volume of the heat exchanger of air conditioner, reduce housing cavity volume of compressor or the like.
The carbon-hydrogen refrigerant rotary compressor that the present invention relates to; Use the lubricant oil of and low solubility not high with the carbon-hydrogen refrigerant intersolubility; Can reduce the quality of the carbon-hydrogen refrigerant that is dissolved in the interior lubricant oil of housing of rotary compressor, also can be so that the carbon-hydrogen refrigerant enclosed volume of whole air-conditioning system descends.
It is 15 square metres to be used for room area below; Refrigerating capacity 1HP, about 2500W, setting height(from bottom) is 1.8m; The pairing R290 refrigeration agent of the R290 refrigeration agent air conditioner rotary compressor that the maximum enclosed volume of R290 refrigeration agent is 290g is an example; Adopt the lubricant oil of different solubility, to the comparison of the R290 refrigerant quality that is dissolved with in the lubricant oil in the housing of rotary compressor, like following table two.
Table two
Wherein, the lubricant oil that sequence number 1 adopted is 30% for the solubility with the R290 refrigeration agent, and the lubricant oil that sequence number 2 adopted is 2% for the solubility with the R290 refrigeration agent.
The solubility of employing and R290 is 2% and 30% lubricant oil comparison, mainly contains two big advantages:
Advantage one: visible by last table; When to adopt solubility with the R290 refrigeration agent be 30% lubricant oil; The R290 refrigerant quality that is dissolved with in the lubricant oil in the housing of rotary compressor reaches 125.4g; The R290 refrigeration agent air conditioner that is 290g for a maximum enclosed volume then, wherein, the quality of participating in the R290 refrigeration agent of refrigeration cycle is 290-125.4=164.6g.
When to adopt solubility with the R290 refrigeration agent be 2% lubricant oil; The R290 refrigerant quality that is dissolved with in the lubricant oil in the housing of rotary compressor is 8.4g; With solubility be 30% lubricant oil relatively, the R290 quality that is dissolved with in the lubricant oil in the housing of rotary compressor can reduce 125.4-8.4=117g.So, maximum to allow enclosed volume be the R290 air conditioner of 290g for one, just can be so that its R290 refrigeration agent enclosed volume is reduced to 290-117=173g, thus the Security of air conditioner could improve widely!
Advantage two: the refrigerating capacity of air conditioner and efficiency; Be related, see Fig. 1-Fig. 2, from figure, can find with the enclosed volume of refrigeration agent; In certain interval range, the refrigerating capacity of air conditioner and efficiency all increase along with the increase of R290 refrigeration agent enclosed volume.
So; With adopting solubility with the R290 refrigeration agent is that the solubility of 2% lubricant oil and employing and R290 refrigeration agent is 30% lubricant oil comparison; The total enclosed volume of R290 refrigeration agent keeping air conditioner all be under the prerequisite of 290g, adopts and the solubility of R290 refrigeration agent is that the quality of the R290 refrigeration agent of the participation refrigeration cycle in the air-conditioning system of 2% lubricant oil will increase 117g, is 164.6+117=281.6g; Therefore, whole air-conditioning system heat or refrigeration performance is improved.
In the present invention, set the use carbon-hydrogen refrigerant, like propane R290 or propylene R1270 etc., the lubricant oil that rotary compressor adopted, under different several working conditions, the solubility of lubricant oil and carbon-hydrogen refrigerant such as following table three.
Table three
Lubricant oil is any one in mineral oil, ester class oil and the polyethers oil, or any combination more than two kinds.
Because the lubricant oil among the present invention and the solubility of refrigeration agent are lower, so under the working state of compressor, after lubricant oil has dissolved a spot of refrigeration agent; Oil body can not descend too big; Therefore require lubricant oil at pure oil condition, just when not dissolving refrigeration agent, oil body can not be too high; Otherwise can make when compressor operating, need expend more power consumption for the viscosity that overcomes lubricant oil.
