Product Description

Cabinet type air conditioner

Product Description

The water-cooled unit need connect to the power supply and cooling system when use. The air-cooled type only need to connect the indoor unit and the outdoor unit, can achieve the effect of improving the air quality and regulating the indoor air environment without a cooling water system. The unit can be used in medical, chemical, electric power, shopping malls, catering, machinery and other industries.

1. Compressor
The unit adopts high-efficiency flexible scroll compressor, which has excellent anti-liquid impact ability, high efficiency,
Low noise, stable performance, reliable operation, long life and other characteristics.

2. Shell and tube condenser
The water-cooled unit adopts a bright tube condenser, the refrigerant condenses in the shell and tube to remove heat, and the condensed water flows through the tube to absorb heat.
Steel shell: The cover plates at both ends of the shell are detachable for easy cleaning and maintenance.

Copper pipe: high-efficiency outer scale steel pipe.

3. Finned condenser and evaporator
Aluminum fins are cascaded outside the copper tube, matched with a large torsion angle fan and a special motor, with large air volume and low noise.
 

Copper tube: Use high-efficiency internally threaded copper tube.

 

Aluminum fins: The use of secondary stamping and flanging technology and double corrugated sheet design, processed by mechanical tube expansion technology, ensure that the aluminum fin and the copper tube are closely combined to obtain the best heat exchange effect.

4. Control system
Including power protector and microcomputer controller. Microcomputer controller adopts well-known brand wide temperature type

Electrical components and microcomputer controllers can operate stably and reliably at ambient temperatures from -15C to 65C, and have complete automatic control functions that can realize remote control.

5. Operation and safety equipment

High and low voltage switch:Protects the compressor from damage caused by high pressure or low pressure.

 

Oil heating belt: Each compressor is equipped with an electric heating belt. When the compressor stops, the oil heating belt heats up. Prevent the refrigerant from mixing and diluting with oil. 

Note: When the unit is shut down, do not cut off the power supply to ensure that the oil heater of the unit continues to work.

After the power is cut off and before restarting, make sure that the oil heating belt has been heated for 8 hours or the oil temperature has reached 23°C or higher.
 

Temperature control: Using microcomputer controller.

 

Filter drier: Filters out impurities, acids and oily particles in the refrigerant in the system, and absorbs moisture in the refrigerant system. The filter drier has a large effective area and extremely low pressure drop.

 

Thermal expansion valve: Control the flow of refrigerant to meet the capacity requirements of the unit.

 

Overload protector: When the motor load current exceeds the rated value, stop the motor to protect the motor from burning.

 

Power protector: Prevents the compressor from operating in reverse or under-phase due to over-high or under-voltage.

 

Unit base: The sheet metal structure is reliable and corrosion-resistant.

 

Assembly: All are assembled on the unit base in the factory, and all refrigerant pipeline piping and necessary power cord and control line wiring work for the unit are completed.

 

Painting: All the units are galvanized and sprayed with plastic, suitable for indoor and outdoor units, beautiful and corrosion-resistant.

The heating methods include: heat pump heating, electric heating, steam heating, hot water heating, gas heating, etc.;
Th humidification methods include: electrode humidification, dry steam humidification, electric heating humidification, high-pressure micro mist humidification, wet film humidification, etc.

The unit can add flow-sharing section, medium-efficiency filter section, muffler section, air outlet section, etc. as required.

Air inlet and outlet direction: horizontal air supply, top air supply, horizontal return air, top return air, side return air, etc.

The direct expansion air-conditioning unit itself has its own compressor. Because the liquid refrigerant in its refrigeration system is directly evaporated (expanded) in the evaporator coil to absorb heat and cool the air outside the coil, it becomes a direct expansion type.


Because the unit adopts air cooling, no cooling water system is required, so it is easier to install than water chillers, and is especially suitable for areas with scarce water sources. Due to the overall structure, the length of the refrigeration system pipeline is greatly shortened, thereby greatly improving the reliability of the system. Because the whole machine is installed outside the house, it does not occupy valuable indoor space, and there is no noise during indoor operation.
