Construction and operation of Germ Free Pigs' facilities are very expensive because pigs' rooms and other major rooms of the facility require germfree environments. Especially, running the HVAC system of aseptic facilities requires a lot of expenses. However, proper location and efficient shape of outlets/inlets for the ventilation of the room can reduce the excessive running cost. In order to do that, this study proposes alternative location and shape of ventilation outlets/inlets to the existing design pattern in germfree pigs' room. The design condition of this study is the maintenance of adequate temperature(24$^{\circ}C$, $NH_3$concentration level(below 1.5 ppm), and air stream speed(below .25m/sec) in the pigs' room for the summer and the winter together. As the Software Program, FLUENT(Ver. 6.2) has been used for the analysis of proposed ventilation patterns. In conclusion, wall inlets and ceiling inlet/outlet are advisable in summer, wall inlets and ceiling outlets is advisable in winter. As far as the shape is concerned, diffuser type for the ceiling outlet is desirable.

In Korea, the radiant heating system has been widely used as a residential heating method, which has been modernized to use hot water running into the tubes embedded in the floor structure. According to the recent improvement of living standard of residential buildings, the requirement of the thermal comfort and energy saving in heating system has been raised. Until now, the radiant floor heating system has been controlled by room thermostat installed in the living room, but for better thermal comfort, an individual room control method is adopted as an alternative. Therefore, it is necessary to evaluate the control performance between the current control method and the individual room control method. In this study, the control performance between the two systems is evaluated through the field experiment. And the control performances of room air temperature and energy performances are analyzed through the simulation using TRNSYS. Firstly, the simulations are performed in the various outdoor conditions and the flow rates and the simulation results are analyzed for the control performances. Also, to evaluate the energy performance, the simulations are performed under the operating conditions in which the set-point of the room air temperature is fixed or changed according to the schedule of occupancy, and the simulation results are analyzed between the two methods.

Designing the capacitor-run motor for balanced operation is accompanied with the excessive capacitor value and low capacitor terminal voltage of condenser. As a solution for this problems, It was reported the design by equal volt-ampere method. The running characteristics of capacitor-run motor by this method due to the balancing point selection, however, has a room to be studied further. This paper deals with the determination of the winding ratio and capacitor value of a permarient-split capacitor motor by balanced operation and equal volt-ampere method at the different load points. The analysis of the running characteristics of a motor and its designing method also presented for both cases. It concluded that the running characteristics due to the equal volt-ampere operation are very close to the balanced operation.

The Plan for effective usage of living room must be suggested because families primarily use living room for public space. And from the viewpoint of function and decoration. the kind of furniture. furniture occupancy quantity. and the arrangement of furniture have much affect on using a dwelling space. So this study will suggest basic data for a good furniture usage through experiment using scale down models. To analyze the data. frequency and percentage were used by running SPSS $PC^＋$ program. The major results are as follows. In an experiment using living room and furniture models(Scale 1/20). according to the size of space. TV sizes and furniture occupancy quantity were in proportion to size and space of the living room. Also they chose various types of tea-table and side-tables. In small spaces. subjects chose simple arrangement types (no sofa or I type sofa and cabinet). but in large spaces. they chose \ulcorner type or \ulcorner type sofa and cabinet.

This study describes to analyze the cooling load characteristics for a room air conditioner as a function of supply ventilation air when an air conditioner is running An experimental apparatus consists of a test room, a room air conditioner, a humidifier, an electrical heater a supply fan and a controller The reaching time to the inside setting temperature of the room air conditioner with is evaluated theoretically and experimentally in a conditioned space cooling loads such as supply ventilation air, lighting, occupancy and infiltration. In the conditions of cooling loads for the supply ventilation air of 9.5 L/s(0.98 ACH). lights. one Person, and infiltration, the reaching time to the inside setting temperature ($27\;^{\circ}C$ dry-bulb) increases up to $35\%$ more than for no supply ventilation air condition. Theoretical modelling of the reaching time shows good agreement with experimental results.

Trend of mechanical ventilation system applied to apartment house is introduced and feasibility study on installation of the individual room control ventilation as energy-saving method is carried out through field experiment. While initial cost of installation for the individual room control ventilation increases, the running cost is lower than the individual household control ventilation due to automatic flow rate control and reduction of fan power, and the management cost also decreases due to extension of use life of components. As the results of field experiment on $115m^2$-type apartment house, the individual room control ventilation could save the amount of 1,459.5Wh/day when compared with the individual room control ventilation
