I've been listening to my friend say that it's good to supply central air conditioning with two units. He also told me many benefits. Everything can't be good without bad. Do you have any friends to sum it up?

The central air-conditioning heating system with two connections has both advantages and disadvantages. Today, Jingfeng HVAC, the general agent of Trane, takes you to understand this popular trend. . First of all, why is this popular now? Most of the initial reasons are that natural gas is expensive. And it's getting more and more expensive. Beijing used to change coal to gas, but later it was found to be unreliable. It changed coal to electricity and gas to electricity. It is found that the energy efficiency ratio of this system is not bad in such a cold place. Comfort is also high. . . And environmentally friendly. The leader vigorously promoted it at first sight. The key is that the national electricity price is still cost-effective. There are a lot of hydropower projects in China in recent decades. Long-distance power transmission is much more efficient than gas transmission. Let's talk about it. Point 1 can't burn at high temperature. This is inefficient. That is, you can't take care of the radiator, otherwise it's not cost-effective. You have to use air conditioning and heating together to be comfortable. . If it's just cooling. Without fluorine, the system is simple. . The control system has to be done. Otherwise, it will not save energy.
