Commissioning of performance on Energy and Environment of Urban Style Eco-Campus, Part3 An Analysis and Improvement of Air Movement through the Stairs in the Library during Heating Period

Kento MORI, Teruyuki SAITO, Satoru IIZUKA, Masaya OKUMIYA

page： 357-360 2015.9

Language：Japanese Publishing type：Research paper (scientific journal)

We investigated indoor thermal environment and air movement through the stairs in the library with all-air induction radiant air-conditioning system in winter. The results show that hanging partition wall, shielding plate and decrease of exhaust air at the 2nd floor restrain the rise of heated air from the 1st floor to the 2nd and improve the vertical temperature distribution. In addition, it is necessary to decrease the fall of cold air into the downstairs at the same time.

Commissioning of performance on Energy and Environment of Urban Style Eco-Campus, Part2 Evaluation of Thermal Comfort under All-air Induction Radiant Air-conditioning System

Akane MARUYAMA, Teruyuki SAITO, Satoru IIZUKA, Masaya OKUMIYA

page： 353-356 2015.9

Language：Japanese Publishing type：Research paper (scientific journal)

We investigated psychological responses of students and thermal environment in a lecture room with all-air induction radiant air-conditioning system in summer. The results show that the rate of vote in hot and uncomfortable side decreased, although room temperature rose 0.8-1.4oC for 90 minutes of a class. The rate of vote in the appropriate side becomes more than 70% if the room temperature is controlled from 24 to 26oC in the morning classes and is controlled from 25.5 to 26.5oC in the afternoon classes.

A Study on the Method of Window Opening to Use Cross Ventilation Efficiently in Housing

Sayako Kishi, Teruyuki Saito

page： 73-76 2014.12

Language：Japanese Publishing type：Research paper (scientific journal)

This paper aims to suggest a pattern for opening windows to keep the indoor thermal environment acceptable by cross ventilation in summer. Using the ratio of opening area on south and north side Ss/(Ss+Sn) as the parameter, the influence on thermal environment is evaluated by thermal and airflow network model NETS. From the subjective experiment conducted in summer 2013, 80% of subjects could accept the indoor thermal environment when the value of PMV was below 1.67 under the condition of cross ventilation, then this value is used as the upper limit to use cross ventilation. The results of NETS show that cross ventilation rate is influenced by Ss/(Ss+Sn) though the ratio of Ss+Sn to floor area is fixed, and cross ventilation rate calculated on whole housing is maximum at 50% of Ss/(Ss+Sn). Then, we suggest that the appropriate pattern for opening windows makes the value of PMV decrease. In summer, if occupants use cross ventilation in case of PMV below 1.67 and air conditioner in case of PMV over 1.67, it is possible to shorten the time of using air conditioner 1 hour in a single room at the opening pattern of Ss/(Ss+Sn)=61% from Ss/(Ss+Sn)=18%.

A Study on the Evaluation of Thermal Comfort in a Hospital Room with All-air Induction Radiant Air-conditioning System in Winter

Akane Maruyama, Teruyuki Saito

page： 213-216 2014.12

Language：Japanese Publishing type：Research paper (scientific journal)

We investigated physiological and psychological responses in a hospital room with all-air induction radiant air-conditioning system in winter. Four subjects of patient role sat on a bed with futon over waist for the first 60 minutes. After that, they lay down on a bed with futon over shoulder for 30 minutes. The results show that there were many votes around neutral on 'cold - hot' scale and many votes in warm side on 'cool - warm' scale at 20 to 25oC in both sitting position and bedtime attitude. The desire of room temperature becomes 'no change' at around 23 to 24oC in the sitting position and at 19 to 20oC in bedtime attitude. Also, in the sitting position, the rate of 'no change' on the desire of room temperature and 'very satisfied' on the degree of satisfaction becomes higher when SET* is 23 to 24oC, and in bedtime attitude, the desire of room temperature becomes`no change' and no one has dissatisfaction when SET* is 19 to 20oC.
