Payback period (ROI)
Taking into account the energy savings during the use of the Chillair “pre-cool&save”, the Chillair installation cost pays off for 4-9 months of operation.
It should be also taken into account that if the air conditioning and cooling unit is for a long time working at maximum capacity, or condenser are poured with water to cool the incoming air, then over time, there will be a deterioration of compressors and plaque on the condenser.
As a result, the efficiency of the system substantially decreases. Performed calculations show that with this approach (working at maximum capacity, pouring with water) the air conditioning and cooling unit loses on average up to 12 – 18% of its efficiency per year. So, for example, the manufacturer YORK points out that because of the build-up of plaque on the condenser, air conditioning and cooling systems lose up to 30-40% of their cooling capacity.
It should be appreciated that if you pour air conditioning and cooling units with water, plaque build-up problems begin after the second season of using this method. Given this fact, the effect of the use of the Chillair “pre-cool&save” becomes even more important, because it provides a significant reduction in operating costs of air conditioning and cooling units and extends its lifetime. For maximum savings, you should install the Chillair “pre-cool&save” in advance.
