No master and slave module
Any module can be a master module. Different modules can be combined freely regardless of their different capacity. Therefore, units can have various kinds of capacity to meet wide application range. If one unit fails to function normally, the rest of units within the module can operate normally in order to ensure cooling supply of the entire system.
Uninterrupted heating in winter
For modular combination, the number of defrosting modules is set automatically so that not all of the modules will be in frosting at the same time. System performs heating and defrosting in good order for comfortable air conditioning and higher defrosting efficiency.
Module balanced operation
Operation time of module is automatically balanced. This is to avoid overuse of a single module and to extend unit’s service life.
Unit adopts multipoint anti-freezing control. Each module has its own water flow switch to protect itself from frost crack caused by uneven water flow or bad working condition.
High-efficiency hermetic impeller
Heat exchanger has large heat exchanging space, which can effectively prevent clogging caused by foreign matters. With the high-efficiency U-shaped heat exchange tube and new pipeline and flow equalizing plate, flow dividing uniformity and heat exchange capacity are both improved.
Electronic expansion valve
High-precision electronic expansion valve is adopted to realize accurate dynamic flow control and quick response to unit’s working condition. Control accuracy and reliability are both considered. It can perform self-check upon startup to ensure safety and reliability during operation.
Wide operating range
heating: -15℃~24℃; water side output water temperature: 40℃~50℃
