A liquid refrigerant distributor is used for a falling liquid film evaporator. The liquid refrigerant distributor includes a gas-liquid two-phase pipe through which a gas-liquid two-phase refrigerant flows, and a first refrigerant tub including a liquid reservoir section into which the gas-liquid two-phase refrigerant flows from the gas-liquid two-phase pipe. The first refrigerant tub further includes a droplet collector configured to collect droplets contained in a gas refrigerant separated by the liquid reservoir section.

Liquid refrigerant sprayer and falling liquid film type evaporator

A shell-and-plate heat exchanger includes: a shell that forms an internal space and includes a refrigerant outlet at a top of the shell; and a plate stack disposed in the internal space and that includes heat transfer plates that are stacked and joined together. The shell-and-plate heat exchanger is configured to allow a refrigerant that has flowed into the internal space to evaporate. The refrigerant outlet emits a gas refrigerant out of the internal space through the refrigerant outlet. The plate stack forms: refrigerant channels that communicate with the internal space and through which a refrigerant flows; and heating medium channels that are blocked from the internal space and through which a heating medium flows. Each of the refrigerant channels is adjacent to an associated one of the heating medium channels with one of the heat transfer plates interposed therebetween.
