In mordern life,most people's activities are indoor. In school,students study and teachers teache in classrooms. In offices,employees do their jobs in big room. One thing that is very important to them in summer such that they can be working normally and every building almost has one this thing---air conditioner. It is make people feel both bad and good.
Air conditioner can make your room's temperature low. It is savior for people in summer. Everyone in summer always feel hot due to high temperature. People alway stay in low temperature so that they can feel better. Air conditioner makes people more concentrated. People can not pay attention in feeling bad. Therefore,they can pay more attention to their work. For busniess,air conditioner can attract more consumer in their stores.A store keeper must be able to know consumers' needs in order for them to buy thing in his store. Air conditioner is a important equipment for consumers. I think no consumers can stay in hot stores for a long time.
Air conditioner is a expensive machine!. Both of its price and electricity consumption are expensive. Most air conditioner's prices are between 5000 and 50000 TWD. It is based on the size of your room and the functions added to the air conditioner. It consums more electricity than general machines. If you turn on it for a month,you may pay 3.740 TWD to power factory. The cost is not the fact that everyone can accept it.
So,air conditioner can bring advantage and disadvantage for us-low temperature and high cost. Athough cost is high,many people cannot but use it in summer. Beacuse it really feel bad in high temperature.
