About This Product

Features of absorption chiller/heater/freezer

■Diverse thermal energy use

In addition to fuels (gas, oil), various types of thermal energy can be used, such as waste heat from gas engines, steam, and natural solar heat.

■Peak cut

Since thermal energy is the main power, electricity consumption during operation is small. In general, the amount of electricity used for air conditioning tends to increase in the summer, but since absorption chiller/heaters and refrigerators consume less electricity, it is possible to cut peak electricity consumption in the summer.

■Gas/oil switching exclusive firing

Since it can use stockpiled fossil fuels, it can also be used as a BCP measure for hospitals and public facilities that need to operate even in the event of a disaster. Product overview

■Significant reduction in fuel consumption

Developed a hot water heat exchanger that is ideal for solar cooling. Base machine (direct firing 1.43 series) achieves a gas reduction rate of 32% at specific rated operation. The hot water independent operation load factor has also been increased from 50% of the Genelink 1.43 series to 55%.

■Specifications specialized for solar cooling systems

The lower limit temperature of recovered hot water at rated time can now be supported up to 75℃, which is the high efficiency of solar thermal panels. Equipped with control functions for the entire solar cooling system. Contributes to higher efficiency.
