indirect hot water supply

Low vacuum operation in thermoelectricity plant for direct heating offers good benefit, however, operating stability will be influenced with the increasing in heating load of network, therefore concept of conversion of direct heating into indirect heating was put forward.

因此提出适时向间接供热的转换问题。
