A heat exchanger (2) is connected during heating operation to the source side of the heat pump, in which a flow direction reversal of the heat transfer medium can be generated when there is a changeover between heating operation and cooling operation.



3D Microstructures for Rapid Absorption/Desorption in Mechanically Constrained Liquid Absorbents

Thu, 20 Oct 2016 08:00:00 EDT

An absorber or desorber contains one or more micro-channels that have a 3-D structured heat-exchanging surface and a membrane on the microchannel situated distal to the 3-D structured heat-exchanging surface, where the membrane is permeable to a solvent of a solution employed in the absorber or desorber. The 3-D structured surface promotes mixing of hot and cold solution between the 3-D structured heat-exchanging surface and a vapor-exchanging surface proximal to the membrane. The mixing reduces the differences in concentration and temperature of the bulk solution and the solution at the vapor-exchanging surface to enhance the efficiency and rate of absorption or desorption of the solvent.



RARE-EARTH REGENERATOR MATERIAL PARTICLES, AND GROUP OF RARE-EARTH REGENERATOR MATERIAL PARTICLES, REFRIGERATOR AND MEASURING APPARATUS USING THE SAME, AND METHOD FOR MANUFACTURING THE SAME

Thu, 20 Oct 2016 08:00:00 EDT

Provided is a group of rare-earth regenerator material particles having an average particle size of 0.01 to 3 mm, wherein the proportion of particles having a ratio of a long diameter to a short diameter of 2 or less is 90% or more by number, and the proportion of particles having a depressed portion having a length of 1/10 to ½ of a circumferential length on a particle surface is 30% or more by number. By forming the depressed portion on the surface of the regenerator material particles, it is possible to increase permeability of an operating medium gas and a contact surface area with the operating medium gas.



REFRIGERANT CHANNEL SWITCHING UNIT AND REFRIGERATION APPARATUS INCLUDING SAME

Thu, 20 Oct 2016 08:00:00 EDT

A refrigerant channel switching unit is disposed between a heat source unit and a utilization unit to switch flow of refrigerant in the refrigerant circuit. The refrigerant channel switching unit includes a first refrigerant pipe connected to a suction gas communicating pipe, a second refrigerant pipe connected to a high-low pressure gas communicating pipe, third and fourth refrigerant pipes, and first and second electric valves mounted to the first and second refrigerant pipes, respectively. The third refrigerant pipe is connected to the first and second refrigerant pipes and a gas pipe. The fourth refrigerant pipe is connected at ends to a liquid communicating pipe and a liquid pipe. A minute channel is formed in the first or second electric valve. The minute channel enables the refrigerant to flow through the minute channel even when an opening degree of the valve is set to be the lowest degree.
