The split-type controller divides the traditional electronic control board into an internal unit board and an external unit board. The engineering installation is convenient. Just pull a communication line between the indoor and outdoor units.
The fifth phenomenon of the electronic expansion valve opening wider
The water source heat pump controller has three sets of scheduled on/off times every day, supports customized startup screens, and can be remotely controlled via a mobile phone APP
Four phenomena of an expansion valve opening wide
Screw machine controller USB flash drive upgrade program, custom startup screen, custom main interface manufacturer information, contact details, highlighting personality or brand
Two effects of refrigeration by electronic expension valves
The cold storage screw parallel controller has powerful customizable functions, and each press can independently set the loading pressure and unloading pressure
The optimization logic of the low-temperature enthalpy electronic expansion valve of the air source heat pump controller significantly enhances the efficiency ratio, and it features multi-stage adaptive variable target superheat
The j constant temperature and humidity controller features electrode humidification ratio for water intake and drainage, precise control of humidification accuracy, and supports manual water intake and drainage. It also has functions such as timed water change and cleaning
yu screw compressors support high and low pressure, oil pressure, and current detection and protection, as well as limit loading pre-protection, which greatly reduces the frequency of faults, customer complaints, and maintenance costs
Non-standard Customization Cases Story Sharing (5) Ultra-low temperature chiller
The various adjustable manufacturer parameters and flexible custom input and output points of the water source heat pump controller make the machine easy to use as desired
Non-standard Customization Cases Story Sharing (4) All-fresh-air AHU
The screw controller is compatible with three-level and four-level capacitive regulation, stepless adjustment, and supports high and low pressure, oil pressure, current detection and protection, as well as pre-protection for limited loading
Non-standard Customization Cases Story Sharing (3) High-precision Chiller
The screw parallel controller for cold storage supports single-compressor start-up, and multiple parallel connections facilitate the realization of one as a backup and one in use. It supports air cooling, water cooling and evaporative cooling
Electronic expansion valve Optimal opening (5.2) Fixed superheat
Air source heat pump controller, with ambient temperature target tracking, is comfortable and energy-saving. The low-temperature enthalpy increase electronic expansion valve optimization logic can significantly improve the efficiency ratio
Electronic expansion valve Optimal opening (5.1) Superheat degree of the thermal expansion valve
The constant temperature and humidity machine controller features dual cold sources and dual heat sources, supporting various humidification methods such as electrode humidification, electric heating humidification, and ultrasonic humidification
