brief introduction

Central air conditioning is divided into two types: fluorine machines (including multi split) and water machines. Both models have modular machines, and the working principle of these models generally varies depending on the medium used. However, they both follow the law of conservation of energy. Modular machines can solve the problem of machine placement and can be freely combined and added or removed according to the needs of the load. They are very convenient to use. Building air conditioning projects, such as hotels, apartments, hotels, office buildings, shopping malls, cinemas, factories, hospitals, etc., have high requirements for noise and surrounding environment. Central air conditioning modular machines are the ideal choice.

characteristic

The central air conditioning module unit has advanced control, high efficiency and energy saving.

The central air conditioning module unit adopts intelligent control, which can fully automatically control the operation of the unit according to design requirements.

Improved control accuracy and reliability, enabling multi-level energy regulation and even distribution of load between unit modules, reasonable matching of unit output and load, and energy conservation.

When combined with 8 unit modules, the unit can achieve 16 levels of energy regulation ranging from 4.54% to 100% according to the load size, ensuring that the unit always operates economically.

It can achieve remote control function.

foldOverall advantages

(1) Plate evaporator - thermal expansion valve, fan, four-way valve, drying filter, one-way valve, etc. are all made of high-quality refrigeration accessories from home and abroad, and all components are precision machined.

This series of central air conditioning module units have low operating noise and vibration, making them suitable for various types of projects.

The central air conditioning module unit has fast cooling speed, stable low-temperature heating performance in winter, and rapid and thorough intelligent defrosting.

The advanced microcomputer control system has complete safety protection functions and powerful fault self diagnosis capabilities.

(2) Central air conditioning module unit is lightweight and flexible - (Central air conditioning module unit) Easy to operate: This series of central air conditioning module units uses a fully Chinese controller for easy control and maintenance.

(Central air conditioning module unit) Easy to use: No additional facilities are required, such as installing boilers, cooling towers, etc.

(3) Flexible and scalable modular machine layout - The modular machine host adopts air-cooled modular design, which is extremely flexible in layout, whether it is on the ground, platform, or roof.

Modular machines can conveniently and quickly add or remove hosts according to the changing needs of air conditioning loads, and have strong expansion capabilities.

(4) The modular unit saves investment -- compared with the traditional water-cooled central air conditioner, the modular unit can save the whole cooling water system and does not need a special machine room. The modular unit can greatly save building space, save civil engineering costs, and thus greatly reduce project investment.

(5) Modular unit can assist heating - The modular unit air conditioning water system has the option of electric heating or gas boiler, and the gas boiler can provide both air conditioning and domestic hot water.

The modular heating system is safe and reliable. In addition to multiple protections for the heater itself, the modular air conditioning unit can also automatically turn on and off the heater based on the water temperature.

(6) Modular machine can be started in stages - due to the modular design, modular machine units can be started in stages, thereby reducing the impact on the power grid during unit start-up and achieving average wear and tear.

(7) Module machine operation safety - The module machine cooling system is equipped with high and low pressure protection, refrigeration antifreeze protection, winter antifreeze protection, compressor operation protection, water flow switch, water pump, and terminal two-way valve interlock protection.

(8) Easy maintenance of modular units - By removing the maintenance panel of the modular unit, you can easily access any component. The design of modular machine partitions greatly facilitates maintenance and upkeep. The modular machine unit is equipped with multiple temperature and pressure sensors. When the modular machine unit operates abnormally, the intelligent remote controller will sound and light an alarm, display a fault code, and prompt the cause of the modular machine failure, making it easy to quickly solve the problem. The maintenance of a single module does not affect the operation of other modules.

(9) The modular machine has excellent performance and reliability - it uses world-renowned brand accessories and undergoes rigorous performance testing to ensure reasonable unit matching. The modular fully enclosed flexible vortex compressor has a higher energy efficiency ratio; The efficient water side heat exchanger of the modular machine ensures the full utilization of equipment capacity; The air conditioning fan, motor, water pump and other components with superior performance of the modular machine ensure the smooth operation of the unit, with extremely low vibration and noise.
