Flooded type evaporator
Refrigerant is evenly distributed in the evaporator. With flooded type evaporator, evaporation temperature is increased and so is the heat exchange efficiency. Together with screw compressor that is specialized for flooded type chiller, unit’s cooling capacity and energy efficiency ratio is greatly improved. COP can reach 6.2.
New throttle mechanism
Control logic is optimized to calculate the best liquid level automatically and adjust the actual value quickly for satisfactory output. The electronic expansion valve can adjust refrigerant flow and evaporator liquid level accurately and fast to maintain the best partial load efficiency and wide operating range.
Reliable oil return
With the patented high-efficiency oil separator and injection type oil return, unit can still achieve reliable oil return even when it is running under poor working condition. Unit is designed with low oil protection to avoid the risk of compressor damage caused by oil shortage.
Double compressors and double circuits
Double circuits can lower failure rate to a minimum and improve unit’s reliability. Because there are double compressors, in case that one faulted compressor needs maintenance, the other compressor can still perform normally.
High-efficiency and low-noise oil separator
This high-efficiency oil separator is patented. It adopts means such as cyclone separation, inertial impaction, natural deposition, and fractionation by absorption. Oil separating efficiency is up to 99.98%.
Stepless capacity adjustment
Stepless slide valve is adopted to realize quick and accurate capacity adjustment and match it with actual load in real time. Compressor starts up steadily under small current and low load.
