TABLE 1
Figure GDA0002592298660000041
It should be noted that table 1 is a table of the relationship between the PMV value, the air temperature and the relative humidity when the air speed is 0.2m/s, the average radiation temperature is equal to the air temperature, the human body metabolic rate is 1.2, and the clothing thermal resistance is 0.5, and is used for air conditioning refrigeration and/or dehumidification in summer. When the indoor temperature is 26 ℃ and the relative humidity is 30%, the PMV of the air conditioner is 0, and the comfort is optimal; when the indoor temperature is 24 ℃ and the relative humidity is 30%, the PMV of the air conditioner is-0.6 and less than-0.5, the comfort is reduced, and the energy consumption is increased, so that compared with the prior art in which the temperature is simply used as a control object, the PMV is used as the control object, the thermal comfort control effect of the air conditioner is better, and the energy consumption is lower.
Alternatively, when the operation mode of the air conditioner is heating, the PMV may be obtained according to table 2. Wherein, table 2 shows PMVs obtained according to the indoor air temperature and relative humidity when the operation mode of the air conditioner is heating.
TABLE 2
Figure GDA0002592298660000051
It should be noted that table 2 is a table of the relationship between the PMV value, the air temperature and the relative humidity when the air speed is 0.2m/s, the average radiation temperature is equal to the air temperature, the human body metabolic rate is 1.2, and the clothing thermal resistance is 1.0, and is used for air conditioning and heating in winter.

If the query exceeds the limit of the value in the table, the query is processed as the boundary value, for example, if the PMV is 1.2, and if the PMV exceeds the boundary value in table 3, the query is performed as if the PMV is 1.
Optionally, when the working mode of the air conditioner is heating, the frequency change rate Δ F of the nth time period may be obtained according to table 4N.

Specifically, table 4 shows that, when the air conditioner starts heating, the lower the initial air temperature in the room, the smaller and negative PMV is, and therefore the PMV needs to be controlled to increase from a negative value to 0, and the range of fluctuation when the PMV is stabilized is [ -0.5,0.5], wherein, when the PMV is a positive value and is greater than 0.5, it indicates that the room temperature is too high; Δ PMV is positive indicating PMV decrease, the larger the value, the faster the PMV drop; a negative value of Δ PMV indicates an increase in PMV, with smaller values giving a faster rise in PMV. If the query exceeds the limit of the value in the table, the query is processed as the boundary value, for example, if the PMV is-1.2, if the PMV exceeds the boundary value in table 4, the query is processed as if the PMV is-1.
