Intelligent bath technology The smart microcomputer monitors the water volume and outlet water temperature in real time, uses fuzzy control algorithm to perform instantaneous calculations on the set temperature and outlet water temperature, determines the required gas volume and air volume, and uses the variable frequency fan and high-performance gas The valve is coordinated with frequency conversion and cooperates with the intelligent water valve to achieve extremely fast and precise temperature control.
At the same time, water modes such as comfortable, economical, bathtub, and kitchen treasures are provided for different consumer needs to meet various goals.
The rapid constant temperature technology adopts Macro's unique MAC1.0 operating system, which enables 0-second start-up, rapid heating, no need to wait, and no need to wait for the outlet water temperature to be hot and cold.
The heating time of an ordinary gas water heater is about 20 seconds, and the water temperature fluctuates around 3°C when started; the heating time of products using fast constant temperature technology is reduced to 6 seconds, and the water temperature fluctuates within 0.5°C when started.
The intelligent wind resistance system adopts a fully enclosed combustion system and cooperates with the intelligent wind resistance system to increase the wind resistance to level 8 or above. Consumers can use the water heater normally under level 8 winds.
The "dual engine" rapid heating technology adopts the "dual engine" rapid heating technology. When the electric water heater is in the heating state, the heat storage heating pipe starts to perform heat storage heating.
When the electric water heater is in the water state, it automatically closes the heat storage heating pipe and opens the instant heating pipe at the same time. The water temperature of the outlet water increases rapidly through the closed instant heating space, which can achieve a temperature rise of 10K (flow rate 4L). /min), can be turned on and washed in summer (when the inlet water temperature reaches above 28°C), unlimited capacity expansion, saving 53 minutes of heating time (compared to the ordinary 3000W 50L electric water heater 28℃ to 75℃ heating time).
Fully premixed combustion condensation heat exchange technology. Before entering the closed combustion chamber for combustion, the gas and combustion air are fully premixed in the premixing chamber at the optimal ratio, thereby reducing the excess air coefficient and reducing The excess air takes away the heat loss of the flue gas and improves the combustion efficiency.
It is equipped with a die-cast aluminum integrated condensing heater. The large heat exchange area ensures that the heat in the flue gas is fully absorbed and improves thermal efficiency.
The thermal efficiency of products using these two technologies can reach 106. Compared with ordinary gas heating water heater products, the thermal efficiency has increased by more than 12.
DC frequency conversion technology constant temperature combustion control technology The gas heating water heater uses a DC frequency conversion fan, making full use of the advantages of the product's stepless speed regulation to accurately adjust the air volume according to changes in combustion load to ensure that the gas heating furnace is always in the In the best combustion state, the combustion efficiency can always be maintained above 90. With constant temperature combustion control technology, it can greatly improve heating comfort and ensure that indoor temperature fluctuations are within 0.5°C.
Hot water system technology Multi-machine parallel hot water system intelligent group control technology Multi-machine parallel hot water system is composed of heating unit, heat storage unit, control and execution unit, in which the heat source is modular Designed to be connected to a maximum of 8 water heaters, the water pump adopts a 1-use and 1-standby design. The two intelligently allocate working time through the central controller. At the same time, the system has intelligent status monitoring and fault diagnosis functions during startup and operation, which is consistent with the gas hot water system in the industry. In comparison, this system completely solves the customer's problems of limited installation location, unattended operation, large and unstable heat demand, and high maintenance costs.
Gas stove technology The third generation of double high fire combustion technology The third generation of double high fire combustion technology increases the injection gas mixture ratio through the holes beside the nozzle, optimizes the length of the injection tube, and adopts a sinking type Methods such as air separation ducts can effectively improve the primary air injection efficiency, strengthen the uniformity of air mixing and evenly distribute the air pressure in the furnace cavity, thereby ensuring the consistency of the air outlet speed from the fire holes.
Through the optimization of the fire hole ratio, the main fire is moved outward, so that the ratio of the inner and outer fire hole areas of the outer ring fire reaches about 1:2. Combined with the high exhaust elevation angle of 60°, the secondary fire The air can pass through the fire groove spacing more smoothly to reach the flame root of the outer ring fire and the inner ring fire, ensuring sufficient combustion. The thermal efficiency of gas stoves using this technology can reach more than 60%, which is 10% higher than the thermal efficiency of atmospheric combustion gas stoves with the same load.
Range hood technology, pure core diversion technology, net core diversion technology, by setting up two sets of independent oil discharge devices inside, increases the oil discharge area, improves the efficiency of oil pollution discharge, and leaves no dead spots for oil pollution.
Consumers not only save themselves the trouble of cleaning oil stains, keep products clean and extend their service life, but also avoid long-term accumulation of oil stains due to improper installation of range hoods, resulting in kitchen air pollution and even fire safety hazards. .
Disinfection cabinet technology High-temperature dual-core technology disinfection cabinet adopts a double quartz heating tube structure, and multiple heat sources are evenly distributed to heat, which can effectively reduce the temperature difference between the center point of the disinfection space and its surroundings, and avoid damage caused by excessive local temperature in the disinfection space. Tableware can also increase the surrounding disinfection temperature, and the effect is more significant.
The temperature difference in ordinary single-tube structure cabinets is about 45°C, while the temperature difference in high-temperature dual-core structure cabinets is about 15°C. The heating is more uniform, effectively killing germs in corners and ensuring the cleanliness of the disinfection space.
