How to install the double channel air conditioning box?

The dual-channel air-conditioning box is an innovative air-conditioning design concept. The indoor dual-channel air-conditioning box is hoisted on the ceiling, with wide-angle air supply on all sides, which can quickly adjust the temperature without affecting the interior decoration. If the purchase is installed in place, it can also play a role in decorating the ceiling. Ceiling air conditioning in the form of central air conditioning display.

1. ceiling air conditioning unit features.

The structure of the unit adopts certain cold-proof bridge and sealing measures, which can effectively prevent the leakage of cold energy and air leakage at the gap of the unit, and ensure the safe and reliable use of the unit.

(2) There are many ways to return air, which is convenient for matching and combination. It has the function of introducing fresh air, which can effectively improve air quality. Suitable for various engineering environments.

The unit has compact structure, beautiful appearance, small footprint, and convenient installation, maintenance and debugging.

The unit is equipped with multiple safety protections such as high and low pressure, compressor overcurrent and overload to ensure the safety and reliability of the unit.

The multi-system unit adopts group control design, which can effectively reduce the operating cost and minimize the impact on the power grid during startup.

Microcomputer control and fault self-diagnosis function, wire control and remote control can be selected, which is more convenient to operate.

2. ceiling air conditioning box installation.

1. The ceiling air-conditioning box should be installed horizontally in the ceiling interlayer, and the condensate pipe side is allowed to be 5 lower, but not higher, to ensure the smooth discharge of condensate. Adequate space should be left around the box for installation and maintenance.

2. The condensate drain connected to the unit shall be equipped with a water seal of sufficient height.

3. The receiving pipe of the surface cooler is from bottom to top, and the stop valve and filter shall be installed at the water inlet.

4. The air duct linked with the double-channel air-conditioning box should be flexibly linked, and the water pipe linked with the unit should be wound and taken over. The torque should not be too large when taking over to avoid heat exchanger loss. Moreover, the pipeline must be independently supported, and the heavy one is borne by the motor group.

5. The power supply of the dual-channel air-conditioning box is 380V and 50Hz. The motor can only be connected after the power supply meets the requirements. After turning on the power, check whether the fan is running normally. If the fan is reversed, stop the machine to change the phase sequence of the power supply.

6. Fan motor should be well grounded, and provide overload, overheating, leakage and other reliable protection.

The installation of the dual-channel air-conditioning box should select the appropriate air duct according to the air volume and static pressure of the unit. All air ducts should be insulated, and the insulation materials should have moisture-proof layer to prevent moisture absorption.

(1) Air volume regulating valves shall be installed in the air inlet and outlet ducts of the unit to facilitate system debugging and make the air volume and air pressure suitable. The inlet and outlet of the unit shall be flexibly connected with the inlet and outlet ducts.

(2) The unit shall not bear the weight of external pipes, and all inlet and outlet ducts shall be supported and fixed.

(3) When installing the dual-channel air-conditioning box pipeline, the space required for unit maintenance must be considered.

Note: Before connecting the outlet pipe from the outlet of the double-channel air-conditioning box unit to the elbow, the outlet pipe should be kept straight at least twice the outlet length, otherwise it will cause additional wind pressure loss.
