Light wave oven is a kind of domestic cooking oven, known as an upgraded version of microwave oven. The principle of light wave oven is different from that of microwave oven. The output power of light wave furnace is seven hundred or eight hundred watts, but it has special "energy saving" means. The lightwave furnace uses double high efficiency heating by light wave and microwave, which can generate enormous heat instantaneously.
The microwave oven is heated by magnetron, but the light wave microwave combined oven adds a light wave emitter in the microwave oven chamber, which can skillfully use light wave and microwave to heat food. In terms of structure, light wave emitter and light wave reflector are installed in the upper part of the furnace. Light wave reflector can ensure that the focus heat energy of light wave is maximized in the shortest time, which is also an important difference between light wave oven and ordinary microwave oven in structure. Compared with the microwave oven, the light wave oven has many advantages, such as fast heating speed, uniform heating, keeping the nutritional components of food to the maximum, and so on. The main purpose of light wave microwave combined oven is to greatly improve the heating efficiency of microwave oven, and to maximize the nutritional content of food in the cooking process, to minimize the loss of moisture in cooking food. In fact, light wave is the auxiliary function of microwave oven, and only plays a role in barbecue. Without microwave, the lightwave oven is only equivalent to the ordinary oven. The light wave ovens on the market are all light wave and microwave combined ovens, which can be operated by microwave, light wave alone and light wave and microwave combined in use. That is to say, the lightwave furnace is compatible with the function of the microwave oven.
Air conditioner is the room air conditioner. Hanging air conditioner is a kind of unit used to deal with the change of air temperature in the space area (usually closed). Its function is to adjust the temperature, humidity, cleanliness and air velocity of the air in the room (or enclosed space, area) to meet the requirements of human comfort or technological process. First, cooling in the design and manufacture of air conditioners, the temperature is generally allowed to be controlled between 16 and 32 degrees Celsius. If the temperature setting is too low, on the one hand, it will increase unnecessary power consumption, on the other hand, it will cause large temperature difference between indoor and outdoor, people can not quickly adapt to the temperature changes in the room and are prone to colds. Two. Dehumidifier is accompanied by dehumidification during refrigeration. People feel comfortable in the environment relative humidity should be about 40-60%, when the relative humidity is over 90%, even if the temperature is within the comfortable range, people still feel bad. Three, the warming up heat pump type and the electrothermal type air conditioner all have the warming up function. The heating capacity decreases gradually with the decrease of outdoor ambient temperature, and can hardly meet the heating requirement if the temperature is -5 C. 4. Purifying air contains a certain amount of harmful gases such as NH3 and SO2, as well as various odors such as sweat, body odor and toilet odor. The purification methods of air conditioners include: fresh air, filtration, active carbon and photocatalyst adsorption and absorption. A. Replace fresh air: Use fan system to drain indoor humid air outdoors to form a certain degree of negative pressure indoors. Fresh air enters the indoor from all around door and window seams, so as to improve indoor air quality. B. Photocatalyst: It can be regenerated under the irradiation of light, releasing harmful substances such as ammonia, nicotine, acetic acid, hydrogen sulfide and so on, which can be reused. The working principle of air conditioning: compressor compresses the gaseous Freon into high temperature and high pressure gas freon, and then sends it to condenser (outdoor unit) for heat dissipation to become liquid Freon at room temperature and high pressure, so the outdoor unit blows out hot air. Then it goes to the capillary and enters the evaporator (indoor machine). As the space of the evaporator suddenly increases and the pressure decreases, the liquid Freon will vaporize into the gaseous low-temperature freon, thus absorbing a lot of heat, the evaporator will be cooled, and the fan of the indoor machine will evaporate the indoor air. The air blows out of the hair dryer, so the cold air is blowing out. Water vapor in the air will condense into droplets when it meets the cold evaporator and flow out along the water pipe, which is the reason why air conditioning will produce water. Then the gaseous Freon returns to the compressor to continue compression and continue circulation. When heating, there is a component called four-way valve, which makes the flow direction of Freon in condenser and evaporator opposite to that in refrigeration. So when heating, the cold air is blown outdoors and the hot air is blown indoors.
The implementation of the national energy efficiency labeling management system has triggered an energy saving storm in air conditioning, refrigerators and other industries. In the context of rising gas prices, this saving wind has also spread to the market of gas cooker. Some manufacturers have too much water in specific publicity. Therefore, when consumers purchase gas stoves, they should carefully check the relevant thermal efficiency test data reports, so as to determine whether the product is energy-saving or not.
Compared with developed countries, there is still a considerable gap in energy saving and environmental protection technology between domestic gas stove production level and developed countries. The energy efficiency of gas stoves is measured by thermal efficiency, that is, the ratio of the burned gas to the generated heat. The thermal efficiency of some high-quality products of large brands can indeed reach 60%, which is higher than 55% stipulated in the national standard, while the energy-saving propaganda of some products is obviously out of line. At the same time, when some products improve thermal efficiency, carbon monoxide and nitrogen oxides emissions also increase.
In the new national standard for gas cookers just approved by experts in mid-August, several major themes of energy saving, environmental protection and safety were highlighted, and more than 20 revisions were made to the old national standard of 1996. Among them, desktop and embedded gas cooker thermal efficiency indicators have increased to 55%. The previous standard stipulated that the thermal efficiency of the desktop gas stove was 55%, and the thermal efficiency of the embedded gas stove was 50%. At the same time, the new national standard requires gas stoves to achieve low emission of oxides and nitrogen oxides in environmental protection. Embedded gas stoves must also have extinguishing protection devices.
Gas stove energy-saving small common sense stove should be placed in the shelter, or increase windshield, to prevent flames from deviating from the bottom of the pot.
Adjust the size of the inlet to allow the gas to burn sufficiently, and the combustion flame should be blue.
Make preparations for cooking before cooking, and prevent ignition.
When boiling soup or stew, you should first boil it in a big fire, then use a small fire to keep the pot boiling and not overflowing.
Proper use of the rack of the cooker should make the flame flame contact with the bottom of the pan and make the combustion efficiency the highest.
According to the size of the bottom of the pot, adjust the size of the furnace fire, so that the flame should be slightly bent after contact with the bottom of the pot and pot, and the flame should lick the bottom.
The use of large diameter saucepans can save more gas than the bottom pot.
Cooking as far as possible without steaming method, steaming time is 3 times the time of steaming rice.
First, wipe the water stains on the surface of the pot and pot, then put them on the fire, so that heat can be transferred to the pot as soon as possible, saving gas.
The closer the water is to the boiling point, the more heat is needed and the more gas is consumed. Therefore, when boiling hot water, do not add water after boiling, but directly burn cold water to the required temperature, which can save gas.
