Thermo-engineering properties of heating pipes coated with radiant dope in gutter-connected greenhouse

From the viewpoint of the energy efficiency, this paper focuses on the difference of the thermo-engineering capability between the two pipes-common pipes and pipes coated with radiant dope and the influence on the thermal environment in gutter-connected greenhouse by enhancing radiant heat-transfer capability of heating pipe. This result provides a basis for the design of economic gutter-connected greenhouse.
