* Wrote based on the average of [Table 1], [Table 2], [Table 3], [Table 4], and [Table 5]

Change of indoor machine temperature

Measurement date : Prior: July 30th / Post: August 4th Same hours: 1pm ~ 3pm
Measurement details : 25 degrees, the temperature inside the communication station

By referring to contents of [Table 3], it could be confirmed that the performance improved much more after the installation of ECO-SPC even though the air temperature was high. This showed that ECO-SPC largely enhanced the cooler performance like [Table 1] and [Table 2].

Change in the discharge temperature of indoor machine discharge temperature

Measurement date : Prior: July 30th / Post: August 4th Same hours: 1pm ~ 3pm
Measurement details : Maintained an average of 16.1 degrees before installing details|Average temperature of 11.8 degrees after installing ECO-SPC|Deviation temperature: 4.3 degrees

COP increased after the installation of ECO-SPC; in other words, the improved cooling performance led to the decrease of internal temperature and lowered the operation rate of cooler, saving electricity cost as in [Table 2]

Change of outdoor temperature

Measurement date : Prior: July 30th / Post: August 4th Same hours: 1pm ~ 3pm
Measurement details : Maintained the average temperature of 32.8 degrees before installation|average temperature of 31.2 degrees after the installation of ECO-SPC|Deviation temperature: 1.6 degrees

Change in the temperature of condenser exit

Measurement date : Prior: July 30th / Post: August 4th Same hours: 1pm ~ 3pm
Measurement details : Maintained the average temperature of 37.4 degrees before installation|average temperature of 27.9 degrees after the installation of ECO-SPC|Deviation temperature: 9.5 degrees

According to [Table 4], after going by condenser and passing through ECO-SPC, the temperature difference before installation was over 12 degrees at maximum. This equipment helps to maintain the highest performance of cooler by extending the cooler’s [coefficient of performance]

Change of operating electricity and accumulated KW

Measurement date : Prior: July 30th / Post: August 4th Same hours: 1pm ~ 3pm

[Table 5] As shown on the graph, the performance of cooler increases after installing ECO-SPC and the operating electricity and accumulated KW decrease, resulting in the effect of saving electricity cost.
