Holtop, a leading innovator in HVAC solutions, is proud to announce the launch of its latest product: the Holtop AHU Falling Film Type Water-Cooled Screw Chiller (Heater) Water Unit. This state-of-the-art unit, with a cooling capacity ranging from 85RT to 690RT, is set to provide strong support for energy conservation and consumption reduction in air conditioning systems across various building sectors.
At the core of this advanced unit is a high-efficiency semi-hermetic screw compressor from an internationally renowned brand. Boasting a new screw profile design and high-precision machining technology, it ensures efficient compression efficiency and stable operation under different working conditions. Equipped with a high-precision capacity control valve, it can adjust the refrigerant flow in real-time and efficiently, significantly reducing operating costs.
The unit adopts a full falling film evaporator design, which effectively reduces the refrigerant charge. Through spray falling film technology, the refrigerant uniformly forms a liquid film on the surface of high-efficiency heat exchange tubes, achieving film evaporation and significantly improving the heat exchange efficiency of the evaporator.
To ensure reliable and efficient operation of the compressor, the unit features a three-stage oil return technology. This technology guarantees proper lubrication of the compressor and prevents excessive oil from entering the system, which could otherwise affect heat exchange efficiency.
A high-precision electronic expansion valve with an advanced balanced orifice design is incorporated, enabling bidirectional flow and excellent sealing performance. This allows for more precise control of the evaporator's liquid supply.
In terms of safety, the unit is equipped with a comprehensive range of protection features, including water temperature anti-freezing protection, water cut-off protection, high-pressure protection, low-pressure protection, overcurrent protection, power supply protection, exhaust temperature protection, and sensor fault detection. Combined with intelligent pre-inspection technology, these ensure the unit operates safely in complex working environments.
The unit's microcomputer control system offers intelligent trend prediction, remote control, self-diagnosis, and safety protection functions. It can adjust the operating status in real-time and, using precise sensing and intelligent control algorithms, achieves stable operation with no deviations throughout the process.
This unit is a comprehensive embodiment of "high-efficiency heat exchange + intelligent control + system synergy". Its energy-saving advantages run through the entire life cycle of the equipment, from real-time operating energy efficiency to the total life cycle cost.
Holtop's new AHU Falling Film Type Water-Cooled Screw Chiller (Heater) Water Unit is poised to set a new standard in the HVAC industry, offering unparalleled efficiency, reliability, and intelligence for modern building air conditioning systems.
