How does full heat exchange work?

The working principle of the fast net full heat exchange fresh air system: double air inlet and outlet. The indoor polluted air and the fresh outdoor air meet in the fuselage through the heat exchanger, and due to the temperature difference and the difference in the partial pressure of the water vapor, the two air streams will exchange heat in the full heat exchanger, and the temperature will be exchanged through air flow and heat conduction.

This process is done through a flat partition. Fresh air and dirty air are exchanged through two adjacent channels of the heat exchange core, and the heat of the exhaust air is transferred to the fresh air for heat transfer, and the channel is completely isolated, which isolates cross-contamination to the greatest extent and saves energy while ensuring fresh air.

The unique heat transfer material is adopted, and the mass and heat transfer are transferred at the same time; Counter-current heat exchange mode, the full heat exchange efficiency can reach 75;

ABS frame structure, low wind resistance, no shrinkage and deformation, sturdy and durable, easy daily maintenance;

The air permeability of the heat exchange material is very low, and the two air streams of fresh air and dirty air are completely isolated without cross-contamination;

Full heat exchange, no condensation, no frosting, no freezing;

It can be combined with modules to maintain low wind resistance and realize the application of large air volume products;

How it works: When there is a temperature difference between two air streams, heat transfer or heat exchange will occur through different temperatures at both ends of the heat conduction plate. The flow of air is conducted with heat to exchange temperature.

The fresh air and exhaust air pass through the two adjacent channels of the aluminum core, and the heat exchange is carried out through the flat plate, and the heat of the exhaust air is transferred to the fresh air, and the adjacent channels are completely isolated to prevent cross-contamination to the greatest extent.

Principle: The compressor compresses the refrigerant into a high-pressure saturated gas (ammonia or freon), which passes through the condenser.

Condensation. After throttling through the throttling device, it is passed into the evaporator.

, the medium to be cooled is cooled and heat exchanged. For example, if the evaporator is connected to each room in the building, the snake pipe in the evaporator will exchange heat with the air, and then blow the cold air into the air in the room through the air blast.

The refrigerant in the snake tube of the evaporator becomes low-pressure vapor after heat exchange, returns to the compressor, and is then compressed by the compressor, so that the recycling completes the refrigeration system.

Heating and cooling principle.

Same, i.e., inverse Carnot cycle.

Different from the refrigeration principle is the exchange of condenser and evaporator, i.e.: compressor - evaporator - throttling device - condenser.

The working principle of the heat exchanger, in fact, is very easy to understand, which is the heat exchange between cold and hot media.

Heat exchangers work by transferring part of the heat to a cold fluid to meet the specified process requirements.

Heat exchanger, also known as heat exchanger or heat exchange equipment, is a device that transfers heat from hot fluid to cold fluid to meet the specified process requirements, and is an industrial application of convection heat transfer and heat conduction. Household heat exchangers help people solve the problem of collective heating of homes and hot water in winter. At present, the more popular one on the market is the stainless steel heat exchange locator.

According to the data of the heat exchange equipment promotion center, the heat exchange effect of stainless steel heat exchanger has a better heat transfer effect than that of traditional carbon steel heat exchanger, and its service life is longer.

Heat exchanger

Heat exchangers can be classified in different ways. According to its operation process, it can be divided into three categories: wall type, hybrid type and regenerative type; According to the compactness of its surface, it can be divided into two categories: compact and non-compact. Among them, the eddy current hot film heat exchanger adopts a stainless steel heat exchanger with the latest eddy current hot film heat transfer technology, which increases the heat transfer effect by changing the fluid movement state.

When the medium passes through the surface of the vortex tube, it strongly washes the surface of the tube, thereby improving the heat exchange efficiency. Up to 10000W m2. This structure realizes corrosion resistance, high temperature resistance, high pressure resistance, and anti-scaling functions.

The fluid channel of other types of heat exchangers is in the form of a fixed direction flow, which forms a circumferential flow on the surface of the heat exchanger tube, and the convective heat transfer coefficient is reduced.

A full heat exchanger usually refers to a kind of fresh air and exhaust air ventilation equipment containing a full heat exchanger core.

Uses of full heat exchangers:

In small household air conditioners or VRV air conditioning systems, due to the lack of fresh air, the indoor air quality is poor, and a thermal device needs to be used in the system. The full heat exchanger is a high-efficiency and energy-saving heat device, which preheats or precools the fresh air introduced into the air conditioning system through the waste heat in the exhaust, and reduces (increases) the fresh air enthalpy value before the fresh air enters the room or the surface cooler of the air conditioning unit for heat and humidity treatment. It effectively reduces the load of the air-conditioning system, saves the energy consumption and operating costs of the air-conditioning system, effectively solves the contradiction between improving indoor air quality and air-conditioning energy saving, and plays an irreplaceable role in the field of air-conditioning system energy saving.

The working principle of the full heat exchanger is to send the outdoor fresh gas into the room after filtration, purification, heat exchange treatment, and at the same time, the indoor polluted harmful gas is discharged outside after heat exchange treatment, and the indoor temperature is basically not affected by the fresh air.
