How is the outdoor dry-bulb temperature for air conditioning in summer determined? Answer: For the outdoor dry-bulb temperature calculation of air conditioning in summer, the average dry-bulb temperature over the years is used, with no guarantee that 50 hours of such temperature will be recorded
The average dry-bulb temperature over the years, without a guarantee of 50 hours, is used.
For the outdoor dry-bulb temperature calculation of air conditioning in summer, the average dry-bulb temperature over the years, excluding the 50 hours for which assurance is not provided, should be used.

For the outdoor dry-bulb temperature calculation of air conditioning in summer, the average dry-bulb temperature over the years, ensuring a minimum of 50 hours of data, is used
For the outdoor dry-bulb temperature calculation of air conditioning in summer, the average dry-bulb temperature over the years, excluding the 50 hours for which assurance is not provided, should be used. Since the establishment of automatic weather observation stations across the country only began in recent years, most areas do not have hourly temperature records spanning 30 years, which are required by statistical standards. Therefore, the 50-hour non-warranty referred to in this clause is based on timed temperature recordings taken 4 times a day (at 2, 8, 14, and 20 o’clock), with each recording being counted as representing 6 hours.
