Multiple cooling-storage containers are arranged in respective spaces formed between neighboring refrigerant tubes. The cooling-storage container is made of a pair of outer envelope portions, each forming a side wall. Multiple convex portions and concave portions are formed in the side walls so that air passages are formed between refrigerant tubes and the concave portions. A sectional area of the air passage formed in a lower portion of the cooling-storage container below a predetermined height is made larger than that of the air passage formed in an upper portion of the cooling-storage container above the predetermined height.

An airplane is provided. The airplane includes an environmental control system coupled to an engine and an inlet. The engine provides a bleed. The inlet provides a fresh medium. The environmental control system includes a compressing device comprising a compressor and a turbine. The environmental control system also includes a moisture removal circuit that separately removes moisture from each of the first and second mediums prior to combining the first medium and the second medium to form mixed air.

A refrigerant and oil treatment composition for introduction into a vapor-compression system such as a refrigerator, heat pump, freezer, air conditioner, thermal control device, and refrigerant recovery apparatus has a composition alcohol and a drying agent. The drying agent is 2,2-dimethoxypropane which can react with moisture in the system to form an alcohol as a reaction product. The alcohol reaction product along with the composition alcohol separates any acid in the system from oil, refrigerant and hard surfaces of the system to form an acid-containing solvent composition. The quantity of the composition introduced into the system is based on the adsorption capacity of the filter-drier.

In an air conditioner, a control section controls at least the indoor expansion valve. The indoor expansion valve has a degree of opening that is controllable. The control section has a condensate formation suppressing control mode and a normal heating control mode. The condensate formation suppressing control mode is performed in a case where a predetermined condensate formation condition is satisfied. The predetermined condensate formation condition relates to generation of condensate formation on the connecting section. The normal heating control mode is performed in cases other than the case where the predetermined condensate formation condition is satisfied. The control section increases the opening degree of the indoor expansion valve when the condensate formation suppressing control mode is performed compared to a case when the normal heating control mode is performed.

The cryogenic refrigeration system of the present invention includes a JT refrigerator and a pre-cooling refrigerator. The JT refrigerator includes a JT valve, which is fully opened during a clog elimination operation, and a first switching valve, which is provided along a low pressure line of a JT circuit and is closed during the clog elimination operation. The cryogenic refrigeration system includes a PL pipe for collecting a helium gas from a helium tank into a buffer tank. The PL pipe includes a second switching valve and a third switching valve, which are opened during the clog elimination operation.
摘要:
Methods are provided for controlling a refrigerated dryer of a gas compressor system. In an aspect, a control system, including a controller and a flow sensor, selectively operates in a power saving mode in which the controller shuts down a refrigerant compressor included in the dryer system when the flow sensor indicates that no compressed gas is flowing through the dryer. The control system uses input from a temperature sensor to determine whether to activate the compressor regardless of the flow of compressed gas through the dryer.

A water extractor includes an inlet, an outlet a body, outer wall, inner wall, helical wall, plurality of catchment areas, and scuppers. The body extends between the inlet and the outlet. The inner wall is disposed radially inward from the outer wall and forms a main flow channel through a portion of the body. The helical wall extends between and is connected to the outer wall and the inner wall and forms a helical passageway fluidly connected to the inlet and the outlet. The helical passageway includes a plurality of turns along a bottom of the body. One of the catchment areas is disposed in each turn of the helical passageway. The scuppers are disposed in the catchment areas and are connected to and extend radially inward from the outer wall.
