Q:The development history of air conditioning

In 1902, American Willis? Design of the first carrier air conditioning system, in 1906, he in the name of air handling unit applied for patent in the United States. Carrier due to a printing workshop, the invention of printing press expansion due to the changes of air temperature and humidity makes paper and paint alignment, print something vaguely. For the carrier to open the door to the air conditioner commercialization. Since 20 years, gradually open the air conditioning is used to adjust the temperature and humidity in the process of production. And in many industries, such as chemical industry, pharmaceutical industry, food and arms industry. In the 20 years after the invention of the air conditioning, enjoy the object has been a machine, rather than people. Carrier engineering company in 1922 to work in the status of air conditioning has a milestone in the history of product -- centrifugal air conditioner, hereinafter referred to as centrifuges. Centrifuge's biggest feature is high efficiency, the air conditioning for large space opened the door. From then on, people become the object of air conditioning service.

Q:Buy a few P good sitting room buy a air conditioning?

Of the sitting room is enough to get 2 p, look at your area under specific estimation, piece-rate words minus the area of the bedroom, the area of the bedroom is good. Frequency of good, of course, is worth it, air conditioning warranty usually have ten or twelve years, with the longer objects don't keen on gaining petty advantages, after came back from the electricity in the province, but also durable, frequency conversion dual-mode best, of course, the most energy saving and environmental protection. Worked as a part-time job, selling air conditioners, said so much

Q:Use battery can drive the air conditioning, can want to much

Ok, but need a high power battery, air conditioning voltage is ac 220 v, need to use a 220 v battery, 1 p air conditioning need at least 1 kw or more battery to drive.

Q:The effect of air conditioner expansion valve? Snow kind of processes are the compressor and condenser - expansion penalty - evaporation box - in the compressor, such right, thank you for directions

Air conditioner expansion valve the refrigeration system of refrigerant in low pressure steam in the compressor and compression for high pressure steam in the condenser to the expansion valve is the high pressure refrigerant liquid at room temperature, after expansion valve throttling into low pressure into the heat exchange at low temperature Cold media, such as making process are: compressor, condenser, expansion valve, have a plenty of capillary) - evaporator - to go back to the compressor

Q:Household air conditioner have drainage pumps?

Not very expensive, I'm not doing maintenance, the price of the parts is not very clear, guess that is more than ten dollars, but you want to confirm that this is the ceiling embedded, other forms of the unit are don't need this stuff, and it is embedded in the one horn of the condensate plate, not highlight the fuselage outside, but inside, if in the outside box can also be a junction box or hook..

Q:What is the high pressure and low pressure air conditioning? How to measure?

Refers to the pressure, inlet gas with back hanging air conditioning can be in commonly add fluoride mouth detection of low pressure process

Q:Can I use my air conditioner as a heater during the winter?

Using your air conditioner as a heater in the winter is not allowed. Air conditioners are designed specifically to cool the air by extracting heat and humidity from the room. They function by taking warm air from inside the room, cooling it, and then reintroducing it back into the room. This process is not suitable for increasing the temperature during the winter months when warmth is needed. If you wish to heat your room in the winter, you will need a separate heating system, such as a furnace, boiler, electric heater, or heat pump. These devices are specifically created to generate and distribute warm air or heat your space efficiently and effectively. It is crucial to utilize the appropriate heating equipment to ensure the safety, comfort, and energy efficiency of your home during the colder months.

Q:Household should choose frequency conversion air conditioning?

Conditions permitting, home air conditioning can choose frequency conversion. Because of frequency conversion energy-saving, save electricity, but the price is expensive than that of fixed frequency. 1, the principle of frequency conversion air conditioning is on the structure of the conventional air conditioning increased by a frequency converter. The heart of the air conditioning compressor, its speed directly affects the efficiency of the use of air conditioning, frequency conversion air conditioning inverter is used to control and adjust the compressor speed control system. It can choose according to environment temperature automatic heating, cooling and dehumidification operation mode, make the bedroom quickly in a short time to reach the required temperature, and in the condition of low speed, low energy consumption with less temperature fluctuation, has realized the rapid, energy-saving and comfortable temperature control effect.

Q:Can an air conditioner cool multiple rooms?

Yes, an air conditioner can cool multiple rooms by using a central air conditioning system, ductless mini-split systems, or utilizing multiple units strategically placed throughout the different rooms.

Q:Household air conditioning how should maintain?

4, need not when seasons: pull out the power plug, take out the remote batteries, in order to avoid accidental damage, cleaning the filter, in order to avoid dirt piles up, the influence is used next time, shielding on the bonnet outdoor, in order to avoid the wind, sun, rain forests.
