1, product features:

1. Patented product, negative pressure operation, safe and reliable
The national patent technology of the fuel/gas direct-fired vacuum hot water unit is a vacuum vacuum equipment, which is not in the category of boilers and pressure vessels. The heat transfer method is indirect heating, which can be an application system. Provide high-pressure hot water, widely used in heating, air conditioning, sanitary hot water and process heat systems.

 

2. Vacuum phase change heat transfer, high efficiency and energy saving

When the unit is running, the body pressure is below 700mmHg. After heating, the heat medium rises to the surface of the heat transfer tube at high speed, so that the refrigerant vapor forms a bead condensation heat transfer on the surface of the heat transfer tube, maintaining a high heat transfer coefficient and adopting international famous brand combustion. Device. With a high burn-up rate, the unit's thermal efficiency can reach more than 93%, saving energy and reducing operating costs.

 

3. Simple heating, wide application of water temperature adjustment

The heating structure of the main machine is safe and reliable. The heated water adopts indirect heating method, which can meet the requirements of low temperature water inflow. It does not need to increase the secondary heat exchange equipment to meet the different temperature requirements of the floor, air conditioner, heating and bathroom. The secondary heating method can be used for different tap water, well water, fresh water, or sea water. Stainless steel, copper tube or titanium tube can be used, and water quality is widely used.

 

4. Maintain vacuum, oxygen-free corrosion, stable heat transfer performance and long life in the machine

The unit is operated under vacuum for a long time. The surface of the machine and the surface of the heat transfer tube are free of scale and oxygen corrosion. It effectively ensures the thermal conductivity and heat transfer performance. The machine is designed for vacuum structure without corrosion or thermal stress. Failure, there is no low temperature corrosion in the combustion chamber due to condensation (the internal hot water temperature is stable and the outer wall of the flue gas is not easy to reach ** temperature), and the working life of the main engine can reach more than 20 years.

 

5. Mechanical vacuum automatic exhaust device (with independent intellectual property rights)

After the unit reaches the design vacuum degree, the heat transfer medium is injected once, and it is used for a long time. There is no need to replenish water during operation. The mechanical exhaust device can automatically discharge the internal condensing gas out of the machine, the heat transfer performance is more stable, and the normal rail machinery is omitted. Pump pumping is inconvenient and easy to damage.

 

6. Intelligent automatic operation, multiple protection, convenient operation and safe use

The unit adopts humanized design program, and has many automatic protection functions such as temperature control, overpressure, over temperature, current interruption, mechanical safety explosion protection, etc. It has automatic adjustment function of system variable load and energy consumption (20-100%). Flue gas emissions comply with environmental emission standards in China's first-class regions, and protect human natural environment to the utmost extent.

 

7. Enhanced convection, efficient heat transfer

The inside of the combustion chamber of the machine is provided with enhanced heat transfer of the convector, fully absorbs the heat in the combustion, and avoids the possibility of damaging the pipe due to the high temperature of the furnace. Eliminate part of the maintenance costs and increase the service life of the vacuum unit.

 

8. Outdoor temperature compensation, energy saving

The controller adopts the outdoor temperature compensation function. With the change of the outdoor temperature, the power output of the vacuum unit is adjusted, heating is performed as needed, the optimal operating condition is achieved, the cost is reduced, and the energy is saved to the utmost.

 

9. One machine is multi-purpose, small in size, light in weight, internationally advanced

This machine can provide two or more kinds of application hot water separately or at the same time, and can provide air conditioning, sanitary hot water, and process hot water for continuous heating. A multi-purpose, direct-fired gas vacuum hot water unit (requires separate configuration of condensing heat recovery unit), its thermal efficiency is up to 98%, saving fuel, and its technical performance indicators have reached the international advanced level.
