Generally the cost can be estimated by 300~400 yuan / square meter to estimate the cost, including equipment and engineering.

Specifically, according to the following two estimates:

1, look at the system, if a single water-cooled water-cooled system, the cost of lower, if the air-cooled cooling and heating system, the cost of higher;

2, look at the building function, if the catering category and other places with a large load, the cost of higher, if it is a home or guest rooms and other places with a small load, the cost of some lower.

89 square meters of central air conditioning probably cost between 30,000 to 40,000 yuan.
