The purpose of this study is to understand the factor that influenced the heating efficiency of the outward and inward multi-hole gas burner. The flame-hole angle and the distance from flame hole to heating object are chosen as the experimental parameter. The measurement of the flame temperature distribution is carried out on each experimental condition. LPG (Liquefied petroleum gas) is used for the test fuel gas. The compositions of LPG are propane 97.5vol%, butane 0.2vol% and methane + ethylene 2.3vol%. It is clarified that the optimum ranges of the flame-hole angle and the distance from flame hole to heating object. The experimental correlation equation is proposed for the outward and inward multi-flame-hole gas burner by design factors.

The purpose of this study is to examine the dehumidification behavior of a block type desiccant unit of organic sorbent. This unit has simple rectangular parallelepiped shape, and initial cost can be lower than the desiccant rotor. This unit will be used in batch system that one unit is used for sorption and another is used for desorption at the same time. Experimental conditions are as follows, sorption air temperature is 18 °C, sorption air relative humidity is 90%, desorption air temperature is 40°C, and desorption air relative humidity is 36%. It was found that completed time of desorption is earlier than that of sorption. As a result, sorption and desorption characteristics of the block type sorbent unit and their overall-mass-transfer coefficients are clarified.

In order to improve the sorption efficiency of the desiccant rotor, double ventilation rotor system has been proposed. In this system, at first the process air is dehumidified in the rotor. Next, the air becomes high relative humidity by cooling with an evaporator, and it is ventilated to the rotor again. In the first report, ventilation experiments of four types of air flow routes were investigated and it is clarified that each route has own characteristics on dehumidification. In this paper, the experiments of double ventilation rotor system of various flow routes were investigated with a refrigerator as a heat pump. Temperature and absolute humidity of the air at the entrance and exit of each zone were measured. Dehumidification amount of the rotor in single ventilation dehumidification system was equal to that in double ventilation dehumidification system. But recovered cold heat from evaporator in double ventilation dehumidification system was higher than that in single ventilation dehumidification system. With increasing the absolute humidity of inlet air, dehumidification amount of the rotor in each route and the absolute humidity of exit air increased. The COP of double ventilation dehumidification system was higher than that of single ventilation dehumidification system.

In this paper, the desiccant rotor with double ventilation system is proposed in order to improve the sorption efficiency of the rotor. In this system, the processing air is dehumidified with the rotor. Next, the air becomes high relative humidity by cooling with an air cooler, and it is ventilated to the rotor again for dehumidification. This desiccant rotor with the organic sorbent has high adsorption ability at high relative humidity and can be recovered at low temperature. In this study, ventilation experiments of four types of air flow routes were investigated. In the experiment, temperature and absolute humidity of the air at the entrance and exit of each zone were measured. It is clarified that each route has own characteristics on dehumidification. As a result, it is found the most suitable route of the double ventilation dehumidification system.

Flow drag and heat transfer reduction effects are useful in heat energy transportation systems and can lead to lower pumping energy requirements. The purpose of this research is to describe the flow drag and heat transfer reduction characteristics of organic (potassium acetate) and inorganic (calcium chloride) brine solutions. The nonionic surfactant oleyl dihydroxyethyl amine oxide (ODEAO) is used as a drag-reducing additive. The pipe friction coefficient and heat transfer coefficient are investigated experimentally in a straight pipe for each type of solution with ODEAO. These coefficients are found to be lower than those of water in the turbulent flow range. However, the rod-like micelles of ODEAO, which are necessary to induce the flow drag reduction effect, are not readily formed in these solutions. Hence, the flow drag and heat transfer reduction effects are measured only under limited conditions and it is difficult to apply these solutions practically as heat transfer media.
