Jiangsu Jincheng Air Conditioning Engineering Co., Ltd. industrial air conditioning - combined air conditioning unit to send you fresh air.
The combined air conditioning unit is an air handling device assembled from various air handling functional sections.
It does not have cold and heat sources. It uses cold and hot water as a medium to complete the filtration and purification of air. Suitable for air conditioning systems with resistance greater than 100Pa.
The air handling function section of the unit has air mixing, current sharing, filtration, cooling, primary and secondary heating, dehumidification, humidification, blower, return fan, water spray, noise reduction, heat recovery and other unit bodies.
Fresh air enters the air conditioning unit and mixes with the return air from the room in the mixing section. The mixed air passes through the primary filtration section to filter out dust and debris, and then through the intermediate filtration section for secondary filtration to filter out smaller dust and debris. Then, through the cold section or the heating section, the air is cooled or heated to reach the desired temperature point, and then humidified to the system by the humidification section to reach the specified air supply state point, and finally processed by the fan section. Good air is sent indoors.

Composition of combined air conditioning unit
1) New return air mixing section: The position of the new air returning port can be set at the end, top or left and right sides according to the design requirements. If it is inconsistent with this sample, the specific opening position should be provided. The regulating valve can be assembled on the new air return. The actuators are available in manual, electric and pneumatic versions, which can be selected by the user.
2) Filter section: There are two types of primary and intermediate filter, with diamond bag type, four-peak bag type, can also be equipped with automatic winding type, high-quality polyester wheel non-woven fabric for filter material, and fast filter with filter. Demolition mechanism, gland display and alarm device.
3) New exhaust section (also called flat-top wind-mixing section): There is a return air valve in the tank body, and a row of air outlets and fresh air outlets are arranged on the top of the box before and after the valve, and the regulating valve is provided. Yes: When there is a return air blower, the air conditioner discharges part of the return air, so that the fresh air and a return air are mixed according to the required ratio; when the DC system is used in the transition season, the return air valve should be closed, the full exhaust air valve and the fresh air valve should be closed. .
4) Energy recovery section: There is a return air valve in the tank, and the top is an energy recovery device. It is a kind of cold (heat) using exhaust air to indirectly cool (heat) the fresh air, and the fresh air passes through the plate energy recovery device. It can recover about 60% of the sensible heat of the exhaust. At the same time, the exhaust and fresh air are not in direct contact, and are especially suitable for energy recovery of DC air conditioning systems that eliminate indoor harmful gases. When used as a DC system, the return air valve should be closed. In places with highly toxic gases, an exhaust system should be provided separately. It is not appropriate to use this section.
5) Middle section (maintenance section): This section is used for the connection of the transition section and the internal maintenance of the unit. Before the filter section, the middle section shall be provided before and after the cold section, the heating section and the muffling section.
6) Secondary return air section: the middle section for connecting the secondary return air duct. The top can be equipped with an adjustment valve. It is equipped with manual, electric or pneumatic adjustment mechanism. It can be selected by the user. This section can also be in the blower section.
7) Surface cooling section: The surface cooler adopts the structure of copper tube string aluminum foil of four, six and eight rows of tubes, the aluminum foil is in the form of double flanged corrugated sides, and the large curved tube heat exchanger reduces the welding elbow by 60%, which improves The heat exchange power and the advanced mechanical riser form ensure the contact performance of the heat exchanger. The heat exchanger is divided into two types: fixed type and rotary type. The user can select one type according to the need, and the heat medium uses steam or hot water.

Installation method of combined air conditioning unit
The combined air conditioning new fan unit is composed of a refrigeration compression condensing unit and an air conditioner.
The combined air conditioning unit is basically the same as the integral air conditioning unit. The difference is that the refrigeration and compression condensing unit is removed from the box and installed near the air conditioner. The electric heater is installed in the air supply duct and is generally divided into three groups or four groups for manual or automatic adjustment. The electrical installations and automatic adjustment components are housed in separate control boxes.
The installation contents of the combined air conditioning unit include: compression condensing unit, air conditioner, air heater, distribution box and control instrument installation. The assembly of each functional segment shall comply with the order of the design regulations.
