An evaluation and model of the Chinese Kang system to improve indoor thermal comfort in northeast rural China – Part-2: Result analysis

The part-2 provides the calibration and validation of the model backbone against the field experimental data. The paper evaluates the simulation results from a myriad of scenarios on their technical ability to increase domestic comfort. Additionally, input from local communities was used to assess rural residents' heating needs and their acceptability of possible solutions. An economic analysis was further used to evaluate the long term feasibility of possible optimized improvements. It was determined that the addition of a room radiator system, consisting of a heat exchanger, water tank, thermostat controls and a panel radiator, delivered the most economical solution in regards to the increasing the resident's comfort per dollar invested.
