The sterilization temperature of disinfection air conditioner is controlled, and is worked under sterilizing operation mode so that air-conditioning is stable, realizes preferably sterilization
Effect.
Under regular situation, the effect of air-conditioning is to adjust room temperature, is controlled often the temperature of air-conditioning to air-conditioning
Leaving air temp or room temperature are controlled.And air-conditioning needs to guarantee in air conditioner indoor unit when working in sterilizing operation mode
The temperature in portion reaches default sterilization temperature, to constitute sterilized environment, could effectively sterilize to air conditioner indoor unit.
In the present embodiment when controlling temperature, control variable is reality of the refrigerant in condensation in indoor heat exchanger

Condensing pressure is 3.18MPa, and upper limit condensing pressure of the refrigerant R410A in air-conditioning is 4.5MPa.
Table 1 is refrigerant R22 saturated liquid and steam thermodynamic property table, by looking into the thermodynamic property table of refrigerant R22 it is found that cold
For matchmaker R22 in the case where pressure is 3.18MPa, saturation temperature is 73 DEG C；Table 2 is refrigerant R410A saturated liquid and steam heat
Power property list, by looking into the thermodynamic property table of refrigerant R410A it is found that refrigerant R410A satisfies in the case where pressure is 4.5MPa
It is 68 DEG C with temperature.Wherein above-mentioned saturation temperature is the state that steam and liquid are in dynamic equilibrium, is applied to indoor heat exchange
In device, saturation temperature is exactly the highest condensation temperature of refrigerant under the absolute pressure.

When one set temperature, the temperature inside indoor unit can be heated to temperature required by sterilized environment by the heat that refrigerant is distributed,
Optionally, the value range of the first set temperature is 62 DEG C~69 DEG C.
First set temperature is adjusting reality lower than the highest saturation temperature for the refrigerant that the air-conditioning of existing configuration can be provided
During condensation temperature, practical condensation temperature is always fluctuated above and below the first set temperature, and the first set temperature is less than air-conditioning
The highest saturation temperature for the refrigerant that can be provided guarantees practical condensation temperature during upper and lower fluctuation, without departing from existing
The highest saturation temperature for the refrigerant that the air-conditioning of configuration can be provided.That is, method for disinfection in the present embodiment can match air-conditioning is existing
It is realized on the basis of setting, the device additional without increase, or uses the air supply rates such as dedicated compressor, heat exchanger, control
The production cost of disinfection air conditioner, improves the market competitiveness.Further, reach default sterilization in the temperature of air conditioner indoor unit
During temperature, air-conditioning always works in normal range of operation, extends the service life of air-conditioning.
The heat that refrigerant is distributed is by being transmitted to indoor heat exchanger surface inside indoor heat exchanger, it may appear that thermal loss,
Optionally, 6 DEG C~7 DEG C of temperature difference of practical condensation temperature and indoor heat exchanger surface are set.In practical applications, basis is needed
Actual conditions measure the temperature difference of practical condensation temperature and indoor heat exchanger surface.First set temperature is higher than default sterilization temperature
6 DEG C~7 DEG C.Optionally, the value range of sterilization temperature is preset are as follows: 55 DEG C~62 DEG C.
Common microbiological all has optimum growth temperature range, growth temperature boundary and heat killing temperature.In environment temperature
After growth temperature boundary beyond bacterium, bacterium stops growing, or even dead.Such as: the optimum growth temperature range of mould is
25 DEG C~30 DEG C, growth temperature boundary is 15 DEG C~37 DEG C；The optimum growth temperature range of saccharomycete is 20 DEG C~28 DEG C, growth
Temperature limit is 10 DEG C~35 DEG C；The optimum growth temperature range of saccharomycete be 35 DEG C~40 DEG C, growth temperature boundary be 5 DEG C~
45℃.After the temperature of microorganism local environment exceeds the most suitable growth range, but still in growth temperature boundary, the life of microorganism
Long speed slows down.After the temperature of microorganism local environment exceeds growth temperature boundary, it is easy to constitute protein, nucleic acid of cell etc.
It wrecks, reduces cell function, if microorganism is in for a long time beyond other than growth temperature boundary when the environment of temperature, constitute
The cell of microorganism is subject to irreversible destruction, until cell death, microorganism is dead.Default sterilization temperature in the present embodiment
Degree has exceeded the upper limit value of the growth temperature boundary of most of microbe, is the heat killing temperature of most of temperature, default at this
Under sterilization temperature, the cell for constituting microorganism is subject to irreversible destruction, until cell death, microorganism is dead.
In a kind of optional embodiment, step S102 judges whether practical condensation temperature reaches in the first set temperature, also
Include:
If so, the practical condensation temperature of record reaches first time lasting after the first set temperature；
Judge whether reach the first setting time at the first time；
If it is not, then air-conditioning continues the state operation for reaching the first set temperature with practical condensation temperature.
When environment temperature reaches heat killing temperature, there are the phenomena of mortality in microorganism, with the growth of time, microorganism
The death rate is got higher, and reaches the progress timing of heat killing temperature duration to environment temperature in the present embodiment.Practical condensation temperature
Degree reaches the first set temperature, while the temperature on indoor heat exchanger surface reaches default sterilization temperature, and practical condensation temperature is the
One set temperature lasting first time, the i.e. temperature on indoor heat exchanger surface default sterilization temperature it is lasting first when
Between, i.e. sterilized environment lasting first time, reach the first setting when the first time of air conditioner indoor unit maintenance sterilized environment
After time, most of pathogenic bacteria and non-pathogenic bacteria can be killed, air-conditioning can exit sterilizing operation mode.
As shown in Fig. 2, a kind of optional embodiment of the present embodiment are as follows:
Practical condensation temperature of the refrigerant in condensation in S201, acquisition indoor heat exchanger；
S202, judge whether practical condensation temperature reaches the first set temperature；If so, thening follow the steps S203；If it is not, then
Execute step S206；
S203, the practical condensation temperature of record reach first time lasting after the first set temperature；
S204, judge whether reach the first setting time at the first time；If so, thening follow the steps S209；If it is not, then executing
Step S205；
S205, air-conditioning continue the state operation for reaching the first set temperature with practical condensation temperature, execute step S203；
S206, the first temperature difference for obtaining practical condensation temperature and the first set temperature；
Practical condensing pressure of the refrigerant in condensation in S207, acquisition indoor heat exchanger；
S208, the practical condensation temperature according to the refrigerant in the first temperature difference and practical condensation pressure regulation indoor heat exchanger
Degree executes step S201；
S209, sterilizing operation mode is exited.
The first setting time in step S204, optionally, the value range of the first setting time are as follows: 20min~
50min。
The first set temperature in step S202 is bigger, and the rate of the microorganism death of air conditioner indoor unit is faster, step
The first setting time in S204 is smaller；First set temperature is smaller, and sterilization rate is slower, and the first setting time is longer.For example,
When first set temperature is 66 DEG C, for the temperature of obtainable sterilized environment at 59 DEG C or so, the first setting time is 30min；That
, if the first set temperature is 63 DEG C, at 56 DEG C or so, the first setting time is more than the temperature of obtainable sterilized environment
30min, optionally, the first setting time are chosen as 30min~35min, obtainable to kill if the first set temperature is 69 DEG C
The temperature in collarium border is at 62 DEG C or so, and optionally, the first setting time is between 25min~30min.It is understood that above-mentioned
The occurrence of first set temperature and the first setting time is merely illustrative, the first set temperature and the first setting time
Relationship is not limited in above content.
The first setting time in the first set temperature and step S204 in step S202 constitutes sterilization conditions, the sterilization
Condition is the condition that microorganism is not easy to survive, and in the sterilization conditions, the microorganisms such as most of pathogenic bacterias, mould are all
Can be dead, realize the bactericidal effect to air conditioner indoor unit.
Preferably, presetting sterilization temperature is 55 DEG C~60 DEG C.Then the first set temperature is 62 DEG C~67 DEG C.
