Hotel Rooms, Air Quality And System Energy Efficiency Study

With the economic development, people's requirement to the living environment is more and more high. After the last decades of 20th century, the storage of energy sources has becoming less and less. And more and more people begin to pay attention to energy saving. People want to living more comfortable, but in another hand, the policy of saving energy limits many ways which can improve the indoor air quality. To solve this problem, we should spend more time researching every factor, which could affect the indoor environment, and master the emphases of it. If we could do these, we can both save energy and protect environment.For this paper, the consuming of energy has been tested in a hotel for one year。Based on energy used has been analyzed. The ways and methods to save energy for hotel have been discussed. In order to avoid infectivity virus diffusing from guest room to aisle, and the possibility of enlarging area infected by virus, some people think that guest room should keep negative pressure. Then, the study for relationship of concentration of carbon dioxide in the guest room and the door for opening or closing have been done. Further more, the affection of fresh air quantity to the concentration of carbon dioxide in the room and the pressure between both sides of the closed door have also been studied. The affection by pressure from fan coil to the concentration of carbon dioxide between room and washing room are also studied.Then, a conclusion has been made that if the air supply and exhaust is well organized, the gap of door could only increase the pressure, and influence IAQ less in room. Of course, it must ensure that it has no danger to healthy first. The pressure from fan coil has little infection to IAQ and pressure between room and washing room.At last, some advices about amount of fresh air have been taken to designers and machine runners.
