Abstract
Because the current air-conditioning load calculation method does not consider the resident's thermal sensation directly, the relationship between the resident's thermal sensation and the load is not clear at the stage of air conditioning system design. To solve this problem, we have shown a new calculation method which can calculate the load by considering the resident's thermal sensation. So far, we have investigated only the sensible heat load calculation model on this new calculation method, but in this paper, we showed a latent heat load calculation model, and obtained the following results. 1) If the air-conditioning load computed by the current method is processed at the optimum point, indoor temperature and humidity are controlled to their set points, but resident's thermal sensation may not be maintained at comfortable range. However, if the load computed by this new method is removed completely, even if indoor temperature and humidity changes, resident's thermal sensation will be maintained at comfortable range. 2) After maintaining demanded thermal sensation, the rate of sensible heat load and latent heat load can be changed as necessary, and the load reduction effect can also be expected.
