Step or unit those of is clearly listed, but may include be not clearly listed or for these process, methods, product
Or other step or units that device is intrinsic.
As stated in the background art, in the prior art, after air-conditioning enters defrost pattern, air-conditioning is run in a chiller mode,
Indoor unit fan parking, interior starts cooling but not return air, so the indoor environment that the temperature sensing package at the return air inlet of air-conditioning detects
Temperature is inaccurate, by the low-temp radiating of indoor set heat exchanger, causes the indoor environment temperature that temperature sensing package detects at return air inlet far low
In indoor actual ambient temperature, poor user experience is caused.
To solve the above-mentioned problems, present applicant proposes a kind of method for showing indoor environment temperature, it can be used for air-conditioning
Real-time display room temperature, as shown in Figure 1, comprising:
S01: the first indoor environment temperature T that air-conditioning enters temperature testing equipment detection before defrost pattern is obtainedBefore defrost；Specifically
, the spacing of the indoor set heat exchanger of temperature testing equipment and air-conditioning is less than first distance, and detection device herein can be sky
Included temperature testing equipment is adjusted, for detecting the temperature of return air inlet as indoor environment temperature, when air-conditioning is in defrost pattern
When air-conditioning according to refrigeration mode run and indoor unit fan parking；Temperature testing equipment can be the included temperature sensing package of air-conditioning or
Temperature sensor, first distance for example can be 5cm, and refrigerant machine heat absorption indoors at this time causes the temperature detection at return air inlet to set
20 DEG C lower than actual temperature of temperature or so of standby detection, the method that the application proposes is preferably applied to winter, and air-conditioning is logical in winter
It is often in heating mode, and at this moment outdoor unit is easy frosting, it is therefore desirable to entering defrost pattern defrosts, air-conditioning during defrosting
Run in a chiller mode, in outdoor unit heat exchanger heat release, machine heat exchanger absorbs heat indoors, at this time the fan parking of indoor unit to prevent
Room temperature is only reduced, at this time low-temp radiating of the temperature testing equipment by indoor set heat exchanger, the temperature of detection is relatively low, at this time
The indoor environment temperature that air-conditioning is shown and the difference of indoor actual ambient temperature are larger, hence it is evident that and it is not right, therefore in air-conditioning entrance
Before white mode, does not enter indoor environment temperature value when defrost pattern with temperature testing equipment detection first, be denoted as the first indoor ring
Border temperature.Before not entering defrost pattern, air-conditioning can be to be run according to heating mode, or shuts down standby mode.
S02: the first indoor environment temperature T is shown during air-conditioning is in defrost patternBefore defrostAs indoor environment temperature.Example
Such as, it detects that room temperature is 15 DEG C before entering defrost pattern, then shows that 15 DEG C are used as interior always during defrost pattern
Environment temperature, specifically, because the room temperature that temperature testing equipment detects during entering defrost pattern is relatively low, it cannot
The temperature value for using temperature testing equipment to detect is shown that otherwise the temperature of its display and interior are real as indoor environment temperature
Environment temperature difference in border is too big, and user is easy to discover mistake.Usual defrost pattern will not run the long time, therefore can use
Indoor environment temperature before defrost pattern found as the room environmental temperature during defrost pattern by inventor's long-term experiment,
During defrost pattern, the difference of temperature value and indoor actual ambient temperature that temperature testing equipment detects has generally reached 20
DEG C or so, and the numerical value that actually indoor environment temperature declines during defrost only has 5 DEG C or so, so the first indoor environment temperature
It spends compared with the temperature value that temperature testing equipment detects closer to indoor actual ambient temperature, it is furthermore preferred that in defrost mould
During time of the operation duration of formula less than 10 minutes, the first indoor environment temperature is shown as indoor environment temperature, air-conditioning exists
Temperature change does not exceed 5 DEG C during defrost pattern is run 10 minutes.
Alternatively, can also be as shown in Fig. 2, executing step S03 after step S01: to the first indoor environment temperature TBefore defrostInto
Row amendment obtains indoor amendment temperature TAmendment, indoor amendment temperature T is shown during air-conditioning is in defrost patternAmendmentAs indoor ring
Border temperature.Specifically, because indoor be in cooling state, indoor amendment temperature is not higher than first during defrost pattern
Indoor environment temperature and the temperature value detected higher than temperature testing equipment described in the moment, because indoor real under defrost pattern
Border environment temperature is not less than the room temperature that temperature testing equipment at this time detects, so, revised interior amendment temperature
It should be above the room temperature that temperature testing equipment detects, for example, being higher than indoor environment temperature in winter makes outdoor environment temperature
When spending, it is no more than 10 minutes because the usual runing time of defrost pattern is very short, indoor amendment temperature should be somewhat below the
The absolute value of the difference of one indoor environment temperature, indoor amendment temperature and the first indoor environment temperature is normally no higher than 5 DEG C.Citing
For: it, can be according to the refrigerant temperature of indoor set heat exchanger and outdoor unit heat exchanger difference and refrigerant when carrying out defrost pattern
Flow determine from the systemic heat in room, the specific heat capacity of volume and each indoor article further according to indoor environment, in addition
The temperature gap of indoor and outdoor determines indoor thermic load, estimates indoor temperature according to the heat that thermic load and refrigerant absorb
Variable quantity, indoor amendment temperature are equal to the first indoor environment temperature plus indoor temperature variation.
In the prior art, the interior that temperature sensing package detects at return air inlet for air-conditioner is only shown in operation of air conditioner defrost pattern
Environment temperature causes the indoor environment temperature of display well below indoor actual ambient temperature, causes user experience low, and this Shen
The method that please be proposed uses the first indoor environment temperature into before defrost pattern as the indoor environment temperature during defrost pattern
Or the first indoor environment temperature is modified, and (10 are usually shorter than the time span that defrost pattern is usually run is very short
Minute), and indoor unit fan parking, so indoor actual ambient temperature will not differ too big with the first indoor environment temperature,
Usually difference is no more than 5 DEG C, and therefore, the problem of the application proposes, which can solve, in the prior art to be shown in defrost pattern air-conditioning
The too low problem of indoor environment temperature.
