Description
Technical field
The present invention relates to a kind of air-conditioner, specifically a kind of heat-production control method of air-conditioner.
Background technology
Current people more and more pay attention to the impact of air-conditioning refrigerant on environment; for protection atmospheric ozone layer; and common practice adopts novel refrigerant R410A or R407C to substitute traditional air conditioner cold-producing medium R22; but these two kinds of cold-producing mediums belong to the HFCS class greenhouse gases of controlled discharge in " Kyoto Protocol "; do not belong to completely desirable cold-producing medium; and natural refrigerant is to environmental impact minimization, it is the long-term desirable material substituted.Wherein, R290 (propane) belongs to natural refrigerant, and depletion of the ozone layer coefficient is 0, and greenhouse coefficient is less, and thermal performance is excellent, is the desirable material that cold-producing medium R22 substitutes for a long time.
Under 54.4 DEG C of saturated liquid conditions, cold-producing medium R290, R22, R410A, the density of R407C is respectively 444kg/m3, 1063kg/m3, 806kg/m3, 1000kg/m3, and the density of oil is generally at about 800kg/m3, therefore the R290 liquid refrigerants bottom compressor can be lighter than oil, oil will sink to bottom, this and R22, R410A, the situation that R407C is heavier than oil is different, therefore need again to investigate cold-producing medium R290 compressor reliability under air-conditioning system most severe condition, and find out the method improving and adopt cold-producing medium R290 in air-conditioning compressor reliability.
Summary of the invention
Object of the present invention aims to provide and a kind ofly improves the heat-production control method adopting cold-producing medium R290 at the air-conditioner of air-conditioning compressor reliability, to overcome weak point of the prior art.
The heat-production control method of a kind of air-conditioner designed by this object, described air-conditioner comprises off-premises station and indoor set, it is characterized in that the heat-production control method of this air-conditioner comprises the steps:
A, air-conditioner are started shooting, and enter heating operation;
B, off-premises station detect outdoor environment temperature, and this temperature is T3, and indoor set detects indoor environment temperature, and this temperature is T1;
Windscreen, the wind-guiding angle of c, indoor set set operation by user, or run by preset value, if desired anti-cool wind mode, windscreen, the wind-guiding angle of indoor set preferentially press anti-cold wind mode operation;
D, when meet T3 < T3A and T1 > T1A time, run N minute relief at air-conditioner by force and enter the running of high wind by indoor fan, and continuous service N1 minute, now, indoor fan wind-guiding angle adopts anti-cold wind angle mode;
E, by force high wind running N1 minute this pattern of backed off after random, air-conditioner is again by normal anti-cold wind mode operation wind shelves;
F, when do not meet T3 < T3A and T1 > T1A time, air-conditioner enters into setting wind pattern by normal anti-cool wind mode;
G, system closedown, again after start, repeat step a-g, wherein, described T3A temperature span is-5 DEG C ~ 20 DEG C, and T1A temperature span is 10 DEG C ~ 20 DEG C.
The span of described N is 3 ~ 8, N1 span is 3 ~ 10.
The cold-producing medium that described air-conditioner adopts is R290.
The present invention, by the operational mode of adjustment air-conditioner, effectively can improve the oil film thickness of compressor operation parts, ensures the oil film thickness of air-conditioner under most bad working environments condition and viscosity, improves the reliability of compressor, guarantee the reliability service of air-conditioner.

Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below in conjunction with drawings and Examples, the invention will be further described.
In general, air conditioner has anti-cold wind function, namely when user heats start, machine can't enter setting wind immediately and run, but progressively stop from blower fan along with the rising of interior machine evaporator temperature, gentle breeze, low wind, finally could arrive setting wind, can certainly stop from blower fan, gentle breeze, low wind, apoplexy again to setting wind or stop from blower fan, gentle breeze, again to setting wind etc., its principle as shown in Figure 1.For the compressor in air-conditioner, refrigerant soak is worst operating mode, and now oil film thickness can reach minimum of a value usually.
As shown in Figure 2, it is a kind of data statistics figure of the air-conditioner coolant deposition adopting cold-producing medium R290 to make refrigerant, and data result shows: after refrigerant soak, and before compressor off-duty, viscosity is still comparatively large, exceeds viscosity apparatus greatest measurement (100cps); After compressor operating, when the 4th minute (viscosity apparatus test in first three minute is inaccurate), viscosity was greatly about 0.68cps, along with pressure increase, viscosity has and declines by a small margin, in 10th minute, machine exits anti-cold wind and enters high wind shelves, pressure drop, and viscosity increases considerably to 1.216cps; Viscosity minimum of a value appears at anti-cold wind and exits eve, and at this moment Δ T only has-24 DEG C, reaches minimum; Whole service process oil film thickness is consistent with the variation tendency of viscosity, namely increases along with the increase of viscosity.
See Fig. 3, the heat-production control method of this air-conditioner, described air-conditioner comprises off-premises station and indoor set, and the heat-production control method of air-conditioner comprises the steps:
A, air-conditioner are started shooting, and enter heating operation;
B, off-premises station detect outdoor environment temperature, and this temperature is T3, and indoor set detects indoor environment temperature, and this temperature is T1;
Windscreen, the wind-guiding angle of c, indoor set set operation by user, or run by preset value, if desired anti-cool wind mode, windscreen, the wind-guiding angle of indoor set preferentially press anti-cold wind mode operation;
D, when meet T3 < T3A and T1 > T1A time, run N minute relief indoor fan at air-conditioner by force and enter the running of high wind, and continuous service N1 minute, now, indoor fan wind-guiding angle adopts anti-cold wind angle mode;
E, by force high wind running N1 minute this pattern of backed off after random, air-conditioner is again by normal anti-cold wind mode operation wind shelves;
F, when do not meet T3 < T3A and T1 > T1A time, air-conditioner enters into setting wind pattern by normal anti-cool wind mode;
G, system closedown, again after start, repeat step a-g.
T3A temperature span is-5 DEG C ~ 20 DEG C, and T1A temperature span is 10 DEG C ~ 20 DEG C.
The span of N is 3 ~ 8, and more preferably 5, N1 spans are 3 ~ 10, more preferably 5.
Wherein, the cold-producing medium that air-conditioner adopts is R290, i.e. propane.
The present invention is by the operational mode of adjustment air-conditioner, effectively can improve the refrigeration oil deposition adopting cold-producing medium R290 to make the air-conditioner of refrigerant, improve the oil film thickness of compressor operation parts, ensure the oil film thickness of air-conditioner under most bad working environments condition and viscosity, improve the reliability of compressor, guarantee the reliability service of air-conditioner.
