Q:The development history of air conditioning

In 1902, Dr Carrier invented the world's first air conditioner, is the industry regarded as "the father of air conditioning" and "expert", etc.

Q:What is the difference between air conditioning and air source heat pump, with what principle?

The scope of the air conditioning is very big, he included the air source heat pump. Air conditioners are divided into: evaporative and absorption. Air conditioning need refrigerant, only to the nature of the refrigerant evaporative often use cold media: R22, R407C, R410a, R134a has a and so on. Absorption often use cold media is: lithium bromide aqueous solution, etc General in refrigeration and air conditioning, it is through the phase change of refrigerant in the evaporator (liquid into gas) absorb indoor quantity of heat, again through the outdoor condenser heat to realize the refrigeration. His is mainly finned heat exchanger heat exchange equipment. And he is in the air air source heat pump low grade can be converted into we can use the high grade. Through the phase change of refrigerant in the evaporator (heat) to absorb heat from the air, and then through the interior of the condenser (or casing heat exchanger), heat release and heat taken from the implementation. This is his state of heating, refrigeration and its general air conditioning, just heat exchanger may be different, often use water as air source heat pump heating medium, through the casing heat exchanger of heat exchange. General air conditioning is ordinary finned heat exchanger. So the air source heat pump used, that is, the principle of air conditioning. At present domestic air source heat pump is more, very miscellaneous, do good giant is not much said, the recent finney is fine

Q:How many degrees electric air conditioning in a day

Air conditioning of electric power is 800 ~ 2000 watts range Large cabinet air conditioning 2000 watts General air conditioning around 800 w ~ 1200 w (of course, vary according to the temperature and air flow) Suppose someone home air conditioning electric power of 1000 watts 24 hours should be 1500 watts when = 36 kw * * 24 (c) At present the electricity price is 0.48 yuan/degree of Beijing For 36 * 0.48 = 0.48 yuan In other words, depending on the air conditioning, electricity will have differences, but generally in 15 ~ 20 yuan (suspension) The scope of 30 yuan (the cabinet)

Q:How long it will take air-conditioning on the right

Air conditioning bring comfortable at the same time, also bring a kind of "disease". In the air conditioning work under the environment of learning for a long time, because the air circulation, not cannot get improvement environment, there will be a stuffy nose, dizziness, sneezing, tinnitus, fatigue, memory loss and other symptoms, as well as the related and skin allergic characteristics, such as skin firmness in dry, allergies, poor skin. This kind of phenomenon in the modern medicine is called "air conditioning syndrome" or "air-condition disease". To prevent air-condition disease, special remind home air conditioning users: don't open air conditioning, 24 hours a day in the evening or at work to close; 24 hours don't close the window; Don't too low, temperature and outdoor temperature difference not less than 7 ℃; Should often clean the carpet, bed sheets, sofa cover. For central air conditioning users, experts emphasize: response to hotels, restaurants, hospitals, bedding, appliances, curtain, etc to disinfection, often as far as possible let the sun. Supplement: for air-condition disease prevention, (1) use of disinfectants to kill microorganisms in air conditioning unit. Disinfectant can be repeatedly used, to prevent microbial regeneration. (2) because the humidity of air conditioner controller is fuelling the spread of bacteria tool, therefore, the need to increase the dehumidifier, in order to reduce the indoor relative humidity, so as to prevent bacterial growth. (3) after strenuous exercise, do not enter the air conditioning room, lest make open pores suddenly, so as to catch cold catch cold cause disease. (4) the air conditioning room and outdoor temperature disparity is bigger, so stay inside the bedroom shoulds not be long. Should make the skin the chance to sweat, water more, make pore unobstructed, to speed up the metabolism. (5) conditions, it is best to use the open systems model of the air conditioner, to maintain indoor air fresh, circulation.

Q:Household should choose frequency conversion air conditioning?

First, is the product safety defects, frequency conversion air conditioning because of electromagnetic radiation in the European Union to ban, air-conditioning in the United States market share less than 5%; Second, is the local brand inverter lack of core technology, the core of the frequency conversion air conditioning technology, intellectual property rights in the hands of Japanese companies, subsidies subsidies frequency is equal to the Japan air conditioning supplier, China's air conditioning industry can not get the real benefit; Third, frequency conversion air conditioning is generally prices artificially high, secondary energy efficiency constant speed air conditioning has dropped below 2000 yuan, 1 and grade 2 energy efficiency 1 horse frequency conversion air conditioning is more than 4000 yuan; Moreover, frequency conversion air conditioning maintenance average price of 1000 yuan, is as 5 times as the constant speed air conditioning. Fourth, frequency conversion air conditioning does not adapt to the Chinese consumer habits, frequency conversion air conditioning is only save electricity use in six consecutive hours, on and off using the frequency conversion air conditioning instead more power, Chinese consumers don't like Japanese housewives stay at home all day 24 hours with air conditioning, the general boot time about 3 hours.

Q:What is the difference between Marine air conditioning and home air conditioning?

Main difference in heat dissipation, car and home air conditioning by air, Marine air conditioning by water. As long as there is enough to install your ship and heat dissipation space, Ann can be what kind of air conditioning degree, may be only the difference between the durability and price.

Q:How to get rid of air conditioning odor

First step, the washing machine outside condenser and cooling fans, don't need to tear open shell, rinse with tap water, be careful not to get the water to the electrical components. The second step, cleaning the machine filter, open the active shell removed, rinse with water. Within the third step, cleaning machine evaporator, open the active shell off screen can see metal finned evaporator, prepare a bottle of special air conditioning cleaner (generally have large supermarkets sell), in the condition of power into the evaporator inside evenly spray cleaner, wait 15 minutes after the start air conditioning, dirt will with condensed water outflow.

Q:Useful three-phase electric air conditioning is what kind of?

Three-phase air-conditioning outside machine is electric heating and air conditioning compressor is 380 v voltage. To apply to the local power supply bureau, general installation meters must be replaced three phase meters. Need to choose according to use all electric appliance total power meters, choosing a meter power supply bureau will specify what to use electric meter. Socket is four holes, respectively is: A, B, C, PE (grounding protection).

Q:How can I reduce the noise from my air conditioner?

To decrease the noise generated by your air conditioner, there are several measures you can take: 1. Ensure proper maintenance and cleanliness of your air conditioner. Dust and debris accumulation within the unit can lead to increased noise levels. Regularly clean the air filters, condenser coils, and fan blades to ensure smooth and quiet operation. 2. Insulate the air conditioner using soundproofing materials like acoustic foam or insulation blankets. These materials will absorb and dampen the noise emitted by the unit. 3. Conduct a thorough inspection to identify any loose or worn parts such as fan blades, motor mounts, and other components. If any parts are found to be loose or damaged, tighten or replace them as needed to eliminate rattling or vibrating noises. 4. Install anti-vibration pads beneath the air conditioner. These rubber or neoprene pads will minimize vibrations transmitted to the surrounding surfaces, significantly reducing the noise level. 5. Create a sound barrier by placing a barrier or soundproof curtain between the air conditioner and the area where you wish to reduce the noise. This will help block and absorb sound waves, making the noise less noticeable. 6. If the noise persists despite attempting the previous methods, consider relocating the air conditioner to a less disruptive location. This could involve moving it further away from living areas or bedrooms, or even placing it outside if feasible. Remember to prioritize safety and seek professional assistance as necessary when working with your air conditioner.
