What is TOP-Eco?

TOP-Eco® is a Japanese-developed Refrigerant Reacting Pipe designed to help improve the efficiency of qualifying commercial air-conditioning systems through a practical retrofit approach. It is installed in the liquid line between the condenser and expansion valve, where its internal structure stirs the refrigerant to promote liquefaction, potentially improving refrigerant condition and supporting better heat transfer. Actual performance may vary depending on the equipment and operating conditions.

How TOP-Eco® Works

TOP-Eco is installed in the liquid line between the condenser and expansion valve, where its internal structure stirs the refrigerant to promote liquefaction, potentially improving refrigerant condition and supporting better heat transfer, with actual performance depending on the equipment and operating conditions.

The performance of refrigerant dominating the efficiency of a refrigeration cycle
                                                        Refrigerant is a very vital substance transferring heat by circulating between Outdoor and Indoor unit. The heat transfer is done by changing its state in liquid and gas. The efficiency of an air onditioner is entirely dependent on the heat transferring performance of the refrigerant by liquefying (condenstation) and gasification (evaporation) in proper manner. Usually the refrigerant does not liquefy sufficiently in active air conditioners due to various reasons such as its installation environment, service condition, machinery shape, etc.
                                                        Incompletely liquefied refrigerant can not perform adequate heat transfer during the evaporation. This forces the air conditioner into inefficient operation, thus costing wasteful electricty expense.
                                                        Faulty liquefied refrigerant to Deteriorated efficiency to Wasteful electricity expense
The Effect of Reacting pipe
                                                        An unique internal structure instensely stirs refrigerant and atomizes incompletely liquefied gases. Furthermore the improved uneven thermal distribution promotes the liquedification of refrigerant.
