Description Series

Platery copper aluminum heat exchangersmanufactured by the "Region" are designed for heating and cooling air in systems air heating, ventilation and air conditioning different designs.

According to the coolant used heat exchangers are divided into the following groups: VNV 243 (water heater) - as a coolant used hot water; WGO 243 (air cooler) - as an energy carrier used cold water, Ethylene glycol and propylene glycol solutions.
Depending on the purpose, the manufactured heat exchangers can be divided into several groups that have certain constructive features:
1. Water heat exchangers - analogues of KSK type calorificates, KVB and KVC. This type of heat exchangers is designed to replace CSC heat exchangers, KVB and KVC during the reconstruction and repair of existing systems or for use in newly designed ventilation systems.

Subgroups VNV.243: Single-row - are used as closers in ventilation systems or as air heaters not lower than -10 ° C;
double-row - used as air heaters in ventilation systems;
three-row - used as air heaters when used reverse water (water mode 60/40 ° C) or as an air heaters in technological processes (for example, in the chamber for drying a tree);
Four-row - used as air coolers in ventilation systems.

2. Channel air heaters (KVN). The sizes of the frontal sections of KVN correspond to the sections of existing air ducts. Connecting dimensions correspond to the connecting dimensions of channel ventilation elements ( channel fans, channel electrical heaters, channel noiselessness, etc.), which allows them to be used to embed into existing ventilation systems or to replace imported channel air heaters. CVN subgroups: double-row for rectangular ducts - used to heat air in ventilation systems; three-row for rectangular ducts - used as air heaters in ventilation systems, as well as heat exchangers for air curtains; Heat exchangers for round air ducts.

3. Heat exchangers for central air conditioners such as KCCP.

Large copper-aluminum heat exchangers manufactured by technical conditions TU 4663-028-40149153-99, designed to heat and cool air in air heating systems, ventilation and air conditioning of various structures. Heat exchangers are designed for operation in areas with moderate and cold climates (UHL3 according to GOST 15150).

Construction and principle of operation of VNV 243, BOB 243

According to the coolant used heat exchangers are divided into the following groups:

- VNV 243 (water heater) - hot water is used as a coolant;

BOB 243 (air cooler) - cold water, solutions of ethylene glycol and propylene glycol are used as an energy carrier.

The design and technology of manufacturing data of heat exchangers is mainly identical. Constructive I. technological features Each type will be stipulated below. The heat exchanger consists of one or more rows copper pipesoK with an outer diameter of 12 mm, finned heat exchange elements in the form of corrugated plates made of aluminum foil with a thickness of 0.12 ... 0.25 mm. The tubes are combined into groups whose ends are in collectors from steel or copper pipes through which the input and output of the coolant or refrigerant is carried out. To connect to the external system on collectors there are special nozzles providing

welded, threaded or flange connection. In coordination with the consumer, heat exchangers are made with the dimensions of the front section of 200 × 100 (mm) to 3000 × 2000 (mm). Heating or cooling of air occurs when it passes through the heat exchanger in the process of interaction with copper tubes and aluminum plates. Compared to steel carriers, the use of copper-aluminum elements increases heat transfer efficiency and reduces energy consumption, but imposes additional requirements to the installation and operation of these devices.

Design of water heat exchangers It makes it possible to ensure both the direct-flow (the direction of movement of air and the energy carrier coincide) and the countercurrent (the direction of air and the energy carrier movement is opposite) the water connection scheme.

When choosing a scheme, it is necessary to take into account that the operation of the air heater in countercurrent mode allows to obtain an increase of 10% of thermal power, and the use of the direct-flow scheme significantly reduces the risk of freezing the heat exchanger. At the estimated air temperature at the inlet into the air heater above minus 15 ° C, it is advisable to apply the countercurrent scheme, as providing more efficient heat, and with more low temperatures - Directionful, how safer.

For the air cooler, only the countercurrent scheme is applied, since there is no freezing threat.

The heat exchanger of the VNW243 series is presented with water air heaters, where hot water is used as a coolant. The relevance of using such copper aluminum plate heat exchangers Observed in air conditioning, ventilation and heating systems. In areas with a cold and temperate climate, operation will be the most appropriate. What are the design features of such equipment, and what models do we implement?

Design features

The design of DV243 heat exchangers is represented by copper tubes (one or more rows), the outer diameter of which is 12 mm. As heat exchange elements for their fins, corrugated aluminum plates with a thickness of 0.12-0.25 mm are used.

The coolant comes out and enters through copper and steel tubes The collectors in which the ends of the grouped tubes are depicted. The collectors, in turn, are equipped with special nozzles with flange, threaded or welded joints, which provides a connection to the external system. The size of the front secting of the heat exchanger can be 2000,000-3000x2000 mm to the choice of the consumer.

Principle of operation

The interaction with aluminum plates and copper tubes provides air heating while it passes through the heat exchanger. Elements made of copper and aluminum alloy provide lower energy consumption and efficient heat transfer, if compared with steel aircraft. On the other hand, more high demands are presented to the installation and operation of such models.

Thanks to the design features, the water connection can be carried out both by countercurrent and by direct flow scheme. In the first case, the energy carrier and air move in different areas, and in the second - in one direction.

Classification

Heat exchangers The VNV243 must be classified as follows depending on their purpose and constructive differences.

  1. Water heat exchangers, acting in the role of analogs of KAO calorifers, KVB and KSK. This group includes single-row, double-row, three- and four-row models.
  2. Channel air heaters.
  3. The aggregates for central air conditioners KCCP can be used both as part of the air conditioning system and as a separate air heater in the technological installation or ventilation system.
  4. Special heat exchangers designed to solve other technical tasks, except for installation in the air conditioning system.
