An adsorption module has heat medium pipes through which a fluid flows, a porous heat transferring member, and adsorbent. The porous heat transferring member is a sintered body formed by sintering a metallic material that is in a form of one of powders, particles and fibers, and has pores for allowing an adsorbed medium to pass through. The porous heat transferring member is disposed on peripheries of the heat medium pipes and bonded to outer surfaces of the heat medium pipes by sintering. The adsorbent is disposed in the pores. The porous heat transferring member further has an adsorbed medium passage for allowing the adsorbed medium to pass through. The adsorbed medium passage is located between the heat medium pipes, and extends straight and parallel to axes of the heat medium pipes.

Embodiments of the present disclosure relate to controlling multiple Thermoelectric Coolers (TECs) to maintain a set point temperature of a chamber. In one embodiment, a controller receives temperature data corresponding to a temperature of the chamber. Based on the temperature data, the controller selectively controls two or more subsets of the TECs to maintain the temperature of the chamber at a desired set point temperature. In this manner, the controller is enabled to control the TECs such that the TECs operate to efficiently maintain the temperature of the chamber at the set point temperature. In another embodiment, the controller selects one or more control schemes enabled by the controller based on temperature data and a desired performance profile. The controller then independently controls one or more subsets of the TECs according to the selected control scheme(s).

Thermoelectric refrigeration system control scheme for high efficiency performance

A heat storage device includes a reactor, arranged in an exhaust system, having a formed body chemically reacting with ammonia and generating heat, and an ammonia reservoir, connected to the reactor, for storing ammonia. The ammonia reservoir incorporates therein an absorbent physically absorbing ammonia. The ammonia reservoir has a heat-exchanging structure and is temperature controlled by heat exchange with an external heating medium.

Dehumidification and humidification apparatus for vehicles

PURPOSE:To enable to efficiently dissolve heat storage material during heating by a structure wherein heating is performed by providing heating sources, one of which covers the bottom surface and the other of which is vertical to the bottom surface, at the lower part of the heat storage device in a latent heat type heat accumulator, which stores and releases heat by means of phase change. CONSTITUTION:The heat storage device A consists of the heat accumulator 1, the heat storage material 2, a heat exchanger 13 for heating and a radiator 4 for taking-out heat. The heat exchanger 131 for heating, which covers the whole bottom surface 6, and the heat exchanger 132 for heating, which is vertical to the bottom surface 6, integrally constitute the heat exchanger 13 for heating. During the initial stage of dissolution of the heat storage material, the heat storage material 12 is dissolved at the central portion of the heat accumulator 1 by means of the heat exchanger 132 for heating on a form so as to pierce the heat accumulator 1, resulting in leaving undissolved heat storage material 22 on the upper wall surface in the heat accumulator 1. The undissolved heat storage material 22 is dissolved by obtaining heat from dissolved heat storage material 12 lying in the bottom and the central portions of the heat accumulator 1 and developing the convection of the dissolved heat storage material throughout the whole portion of the heat accumulator 1.

PROBLEM TO BE SOLVED: To solve the problem with the dehumidification device of the conventional constitution that an increase in the sizes of aperture is resulted since a hygroscopic honeycomb is rotated. SOLUTION: A hygroscopic body 4 which is liquid movably held is segmented to two blasting circuits and one thereof is arranged in a dehumidification circuit 7 and the other in a regeneration circuit 14. Dehumidified air and cold air can be generated by humidifying condensed water.
