R410A DX Type Water Cooled Floor Standing Air Handling Unit Industrial Air Conditioner

R410A DX Type Water Cooled Floor Standing Air Handling Unit Industrial Air Conditioner

✳️ Product Introduction

✳️ Product Principle

The DX system, also called gas/freon system utilizes the refrigerant—commonly referred to as "Freon", as the primary heat transfer medium. By leveraging the phase transition (between gas & liquid states) of the refrigerant across indoor and outdoor units, the system enables direct heat exchange with indoor air, thereby achieving precise temperature control. The essence is "Refrigerant → Air" heat exchange. So no chilled water or hot water provided by the DX system itself.

✳️ Main Parts

1. Compressor. All compressors of world-renowned brands are adopted to ensure the stable operation of core components and reduce the failure rate. We accept a very wide range of customized power supplies For example, 220V/3PH/60HZ, 380-415V /3PH/50/60HZ, 440V/3PH/50/60HZ, 460V/3PH/50/60HZ, 480V/3PH/50/60HZ. Environmentally friendly refrigerants will also be applicable, such as R410A, R407C, and R134A etc.

2. Condenser & Evaporator (Pipe coil heat exchanger). High-efficiency purple copper tube through corrugated hydrophilic aluminum fin heat exchanger, highly efficient heat exchange and long service life. Transfering heat via refrigerant. Fins expand surface area, enhancing heat exchange with air. Refrigerant changes phase (condenses/evaporates), absorbing/releasing heat. Air flows over fins, facilitating efficient thermal transfer for cooling/heating.

3. Expansion valve. regulates refrigerant flow into evaporators. It reduces high-pressure liquid refrigerant to low-pressure and low-temperature mist via a restricted orifice. Sensing evaporator outlet temperature (via a thermal bulb), it adjusts opening size to match cooling demand. This phase change readies refrigerant for heat absorption, ensuring efficient, stable HVAC/refrigeration system operation.

4. Control systems. The HVAC system dedicated control program independently developed by China Electronics Technology Company provides all-weather operation monitoring for constant temperature and humidity air conditioning units. The touch large screen makes the operation status and parameter adjustment of the unit more convenient, simple and easy to learn. In addition, when used in conjunction with electrical components of world-renowned brands, it greatly reduces the circuit failure problems of the unit, thereby ensuring the normal operation of the entire unit and maintaining a longer service life.

5. Motor and fan, air supply systems. Y series three-phase asynchronous motor. Insulation above Class B, the highest IP54 protection, high efficiency, energy saving, high starting torque, low noise, small vibration, safe and reliable operation. Could be driven by belts or directly, can use variable frequency motors or brand EC fans. It precisely controls the air volume and regulates the air circulation speed, making the airflow more uniform and improving the heat exchange efficiency. Belt drive forward, forward multi-wing centrifugal fan, also could use the VFD fans or EC fans. Fans pass all the static and dynamic balance correction, low noise, static pressure with high efficiency. Unit static pressure could be customized according to user requirements. Centrifugal fan Selecting the appropriate fan based on the air volume and the fan selection software, and pair it with

a high-quality motor. Then, use belt drive to form the power and air supply system of the entire unit.

6. Purified and Constant temperature & humidity accessories. Clean air conditioner filters remove dust, particles & contaminants, ensuring air purity for clean rooms/precision environments. Humidifiers maintain proper humidity; electric heaters regulate temperature, both optimizing comfort and process stability. It is usually applicable to fields such as data centers, hospital operating rooms, biopharmaceuticals, chip production, cosmetics production, medical devices, and R&D and production in the lithium battery industry.

Hot Water Coil Heating; Steam Heating Coil Heating; Electric Heater: PTC ceramic electric heating.

Humidifier. The humidifier is widely used for different application including clean room, spray room, hospital, biology laboratory etc. The humidifier including Electrode humidifier, High pressure mist humidification, High pressure spray humidification, Wet film humidifier etc, which could achive ±5% humidity range.
