air conditioner Unit manufacturer Kaiyi water system midpoint air conditioner manufacturer each functional section of air conditioning unit
New return air mixing section:
The position of the new return air outlet 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 shall be provided. It can be assembled on the new air return outlet Regulating valve There are three types of actuators: manual, electric and pneumatic, which can be selected by the user.
Filter section: air conditioning unit manufacturer Kaiyi water system midpoint air conditioning manufacturer
There are two types of primary and medium efficiency filtration, which are equipped with diamond bag type, four peak bag type, or automatic winding type. The filter material is high-quality polyester wheel non-woven fabric, and the filter quick assembly and disassembly mechanism is used to display and start the emergency signal device.
New exhaust section: air conditioning unit manufacturer Kaiyi water system midpoint air conditioning manufacturer
(also known as the flat roof air distribution mixing section) The box in this section is equipped with a primary air return valve, valve The front and rear box tops are respectively equipped with a vent and a fresh air outlet, and equipped with a regulating valve. Its function is: when there is a return fan, the air conditioner will discharge part of the return air, so that the fresh air and the primary return air can be mixed according to the required ratio; When the DC system is used in the transition season, the primary air return valve should be closed, and the exhaust valve and fresh air valve should be fully opened.
Energy recovery section:
It is used for cross split air mixing and exhaust air energy recovery in the double fan system. The box in this section is equipped with a primary air return valve. The top is an energy recovery device, which uses the cold (heat) of the exhaust air to indirectly cool (heat) the fresh air. After passing through the plate energy recovery device, the fresh air can recover about 60% of the sensible heat energy of the exhaust air. At the same time, the exhaust air is not directly contacted with the fresh air, which is especially suitable for the energy recovery of the DC air conditioning system that removes harmful indoor gases. When used as a DC system, the primary return air valve should be closed door The area with highly toxic gas shall be provided with a separate exhaust system, and this section is not suitable for use.
Intermediate section (maintenance section)
This section is used for connection of transition section and internal maintenance lighting of the unit. In front of the filter section, the middle section shall be set before and after the surface cooling section, heating section and silencing section
Secondary return air section
The middle section used to connect the secondary return air duct can be equipped with a regulating valve at the top and a manual, electric or pneumatic regulating mechanism, which can be selected by the user. This section can also be combined in the blower section.
Table Cold section air conditioning unit manufacturer Kaiyi water system midpoint air conditioning manufacturer
The surface cooler adopts four, six and eight row tubes Copper tube The aluminum foil is in the structure of stringing aluminum foil. The aluminum foil is in the form of double flanging and corrugated edges. The large elbow heat exchanger reduces the number of welded elbows by 60%, which improves the heat exchange power. The advanced mechanical expansion form ensures the contact performance of the heat exchanger. The heat exchanger is divided into fixed type and rotary type. The user can choose one according to the needs. The heat medium is steam or hot water.
