The heat transfer pipes are arranged in the gravity direction. The fin has a water guiding area disposed above and below each of the heat transfer pipes, and a water drainage area disposed adjacent to a side of each of the heat transfer pipes. The water guiding area has water guiding structures for guiding water to the water drainage area. The water drainage area has water drainage structures for guiding water in the gravity direction.

Apparatus for heat storage, comprises a working fluid chamber for storing working fluid; a pressure support chamber coupled to the working fluid chamber and including pressure support material, said pressure support chamber for increasing pressure in said working fluid chamber responsive to compression of said pressure support chamber; a fluid pump for pumping working fluid into the working fluid chamber, wherein pumping fluid into the working fluid chamber increases pressure of said working fluid in the working fluid chamber; the pressure elevation of the working fluid in the fluid chamber is responsive to pumping the fluid back into the fluid chamber to compress the pressure support chamber; a working fluid chamber heat exchanger for varying temperature in said working fluid chamber; an output conduit for transferring working fluid from said fluid chamber to a utilization destination; and an input conduit for transferring said working fluid received from said utilization destination to said working fluid into the fluid chamber.

A laminated fluid warmer includes: a laminate including a target fluid layer having a plurality of target fluid channels through which a warming target fluid flows, and a warming fluid layer that is laminated on the target fluid layer and has a plurality of warming fluid channels through which a warming fluid for warming the target fluid layer flows; and a collection device that collects at least a part of the warming fluid accumulated in the plurality of warming fluid channels. The collection device includes a storage portion that receives the warming fluid flowing out from the warming fluid channel when collecting the warming fluid.

A heat exchanger assembly, an indirect evaporative heat exchanger including the heat exchanger, and methods of operating the same. The heat exchanger assembly includes at least one tube, a plurality of sections, and a plurality of nozzles. The at least one tube is configured to (i) have a process fluid flow therethrough in a first direction and (ii) have a scavenger cooling medium flow over the outer surface of the tube in a second direction. The second direction intersects the first direction. The plurality of sections is aligned in the first direction. The plurality of nozzles are located above the at least one tube. At least one nozzle of the plurality of nozzles is (i) located in each of the plurality of sections and (ii) configured to selectively discharge coolant onto the portion of the tube in that section of the heat exchanger.

A heat exchanger includes a first flow path through which a first fluid flows, a second flow path through which a second fluid flows, and an adjustment layer disposed between the first flow path and the second flow path adjacent to each other and that adjusts an amount of heat exchange between the first flow path and the second flow path. The adjustment layer includes a first portion and a second portion having a heat transfer performance lower than that of the first portion, and has a heat transfer performance varied depending on a position in the adjustment layer.

There is provided a heat storage system including: an indoor space; a heat storage space which is adjacent to the indoor space and in which a latent heat storage material having a melting point or a freezing point in a range of 5 C. or higher and 30 C. or lower is installed; and a natural ventilator controlling introduction and blocking of outside air to the heat storage space, in which a heat resistance between the heat storage space and the outside air is set to be greater than a heat resistance between the heat storage space and the indoor space.

A system for fast draining an airfan heat exchanger includes an airfan heat exchanger comprising a housing, a pressurized gas source fluidly coupled to the airfan heat exchanger and configured to hold a purging gas at a predetermined pressure, and a controller configured to control delivery of the purging gas to the airfan heat exchanger. The pressurized gas source is configured to provide a flow of the purging gas to the airfan heat exchanger and thereby drain water held in the airfan heat exchanger. The purging gas to the airfan will cause the airfan to drain quickly avoiding potential damage to the airfan from freezing of the water during cold weather.
