Specifically, according to the following two estimates:

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

2, look at the function of the building, if the catering class and other places with a large load, the cost of higher, if the guest room and other places with a small load, the cost of some lower.

700 square meters of central air conditioning is probably cost between 180,000 ~ 250,000 yuan.
