product overview

The TYZK series purification combined air conditioning unit is developed by our company based on decades of professional experience in producing air conditioning units and drawing on the advantages of similar units at home and abroad. This unit can cool, dry, heat, humidify, filter, purify air, and has noise reduction function. It can be widely used in places that require centralized air treatment, such as shopping malls, hotels, office buildings, and sports centers, as well as in places where purification air conditioning is required, such as hospital study rooms, pharmaceuticals, cigarettes, food, and precision instrument manufacturing.
The TYZK series combination air conditioning units are divided into two types: universal units (ZK) and purification units (ZKJ). Processing air volume: 2000~200000M3/H.

Each functional section of the 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 should be provided. A regulating valve can be installed on the new return air outlet, and the actuator has three types: manual, electric, and pneumatic, which can be selected by the user.
Filter section:
There are two types of primary and medium efficiency filters, equipped with diamond shaped bag and four peak bag, and can also be equipped with automatic winding. The filter material is made of high-quality polyester non-woven fabric, and the filter adopts a quick installation and removal mechanism, a cover display and alarm device.
New exhaust section:
(also known as the flat top split air mixing section) This section of the box is equipped with a primary return air valve. The box top before and after the valve is equipped with an exhaust outlet and a fresh air outlet, and is equipped with a regulating valve. Its function is to supply air conditioning units with partial return air when there is a return air fan, so that the fresh air and primary return air are mixed in the required proportion; When using a DC system during the transition season, the return air valve should be closed once, and the exhaust and fresh air valves should be fully opened.
Energy recovery section:
Used for cross split air mixing and exhaust energy recovery in dual fan systems. There is a return air valve inside this section of the box, and the top is an energy recovery device. It is a method of indirectly cooling (heating) fresh air by using the cold (hot) exhaust air. The fresh air passes through a plate type energy recovery device and can recover about 60% of the sensible heat energy of the exhaust air. At the same time, the exhaust and fresh air do not come into direct contact, making it particularly suitable for energy recovery in DC air conditioning systems that eliminate harmful gases indoors. When used as a DC system, the return air valve should be closed once, and a separate exhaust system should be installed in areas with highly toxic gases. This section should not be used.
Middle section (maintenance section)
This section is used for the connection of the transition section and the internal maintenance lighting of the unit. Before the filtering section, a middle section must be set up before and after the surface cooling section, heating section, and silencing section
Secondary return air section
The middle section connected to the secondary return air pipe can be equipped with a regulating valve at the top, which is equipped with manual, electric or pneumatic adjustment mechanisms. Users can choose from this section, which can also be combined with the supply fan section.
Cold section
The surface cooler adopts a structure of four, six, and eight rows of copper tubes with aluminum foil in series. The aluminum foil is in the form of double flanged corrugated edges. The large bent tube heat exchanger reduces 60% of the welding bends, improving the heat exchange power. The excellent mechanical expansion tube form ensures the contact performance of the heat exchanger. The heat exchanger is divided into fixed and rotary types, and users can choose one according to their needs. The heat medium is steam or hot water.
