摘要： PURPOSE:To make it possible to adjust the length of the flowpath to change a heat exchange area and to adjust the heat exchange efficiency by making variable the pressurizing force in the overlapped direction of the heat exchange element, in a pi-flow type heat exchanger. CONSTITUTION:A pressurizing force 6 is applied to the heat exchanger in the laminated direction of the heat exchange element 1. In this case, the pressurizing force is released, and the heat exchange element 1 is caused to slide in the direction of the parallel flowpath 1a to narrow the width of the overlapped portion 5 of the heat exchange element 1. Then, the pressurizing force 6 is again applied to pressfit the overlapped portion 5 to prevent air leakage. Thus, by causing the heat exchange element 1 to slide, the length of the flowpath can be elongated, and the heat exchange efficiency can be increased by enlarging the heat exchange area.

摘要： PURPOSE:To enable purification of air by gradually varying the area of an air supply opening made in radial direction of body by means of a rotary member thereby varying the blowing direction of air and achieving the circulation effect for mixing the room air. CONSTITUTION:Upon driving of a fan 2, air is fed through an air intake port 3 and purified through a filter 3A then led to the centrifugal diffuser path 7 and blown into the room through an air supply opening 4. Here, the opening area of each air supply opening of the air supply opening wall section of body 1 or a fixed supply grill 1A is varied gradually through rotation of a rotor or a centrifugal supplly grill 8 thus to sequentially vary the circumferential supply direction at each air supply port 4. Since the air supply openings 4 are provided at plural positions in the fixed supply grill 1A, the supply direction will vary gradually over the entire circumference of said grill 1A. Consequently, the circulation effect through mixing of room air is achieved resulting in purification of air.

摘要： PURPOSE:To enhance the heat exchange efficiency of a heat exchanger by a method wherein both or either one of two fluids to be heat-exchanged with each other is given the specified flow rate distribution. CONSTITUTION:Partition plates 1 are laminated with the predetermined intervals in a plurality of layers so as to pass primary fluid and secondary fluid through alternate layer in the directions intersecting each other. At the same time, a fin 2, which forms a plurality of parallel passages together with the partition plate 1 to control the flow of said fluid, is provided between the partition plates of each layer. In addition, the sectional area ratio or the open area ratio per unit length of the parallel passage in the layer, through which at least one fluid out of the two fluids, at the lead-in port side is made different from that at the lead-out port side. Thus, the change of flow rate due to the change of the open area ratio of the parallel passage 2a is given to both or either one of the primary fluid and the secondary fluid leading in the respective layers so as to perform the heat exchange between the primary fluid and the secondary fluid through the partition plates 1 and, after that, to discharge from the heat exchanger. Consequently, the high heat exchange efficiency of the heat exchanger is obtained.
