The Flash Injection Circuit is a patent-pending technology, which consists of a Heat Interchanger (HIC) and a compressor equipped with an injection port. It works by allowing for a portion of two-phase refrigerant (gas-liquid) to bypass the outdoor coil, and recollect heat energy at the Heat Interchanger (HIC) that is normally rejected during the flash process in the outdoor unit. The Flash Injection Circuit then injects the energized two-phase refrigerant at a lower temperature into the compressor through the injection port during the compression process. This reduces the temperature inside the compression chamber, allowing the compressor to run at higher speeds to offset the effect of low suction pressure and the low refrigerant mass flow rate.

As a result, Zuba-Central is able to maintain a high heating capacity and achieve higher performances without being affected by the cold.

Our advanced Variable Compressor Speed Inverter (VCSI) Technology provides exceptional high-speed heating and cooling performance, energy-efficient operation, and most importantly, the experience of unmatched comfort.

Conventional compressors work on cycles where the system starts up and stays at a fixed speed until it overshoots the set temperature, and then stops until the next cycle begins. This on-off cycle causes unnecessary energy spikes and also consumes high amounts of energy, regardless of the actual requirement, as the system is always producing the maximum amount of cooling or heating even when the demand is low. This results in a tremendous amount of wasted energy and uncomfortable energy fluctuations.
