Принадлежит: Individual

A modular compressed-gas dryer including in series: an inlet module, a precooler/reheater module, an evaporator module, and a sump module. The modules form columns where at least one column has a filtration chamber. Further provided are a gas outlet and gastight seals between modules. The system creates a first and second set of heat transfer passages where refrigerant passes through the second set in a heat exchange relationship in a direction perpendicular to incoming gas passing in the first set. The filtration chamber conducts chilled gas from the first set to a third set of heat transfer passages. The third set extends through the precooler/reheater in heat exchange relationship with the first set. Chilled gas passes in heat exchange relationship in a direction perpendicular to the incoming gas so that the incoming gas chilled in the evaporator exchanges heat with the incoming gas in the precooler/reheater.

An anti-microbial heat transfer apparatus comprises a hybrid coil with multiple rows of fins and tubes. The fins and tubes have an upper portion and a lower portion. The upper portion comprises fins that include copper and has a height that is different than the height of the second portion.

A combination refrigeration displacement and drain device is disclosed that can be mounted within a heat exchanger, such as a shell and tube heat exchanger, which may be used for example as a heat exchanger in a chiller unit, which may be used in an HVAC or refrigeration system. One example of such components can include heat exchangers, such as for example a condenser employing a gravity drain. Advantageously, the combination refrigeration displacement and drain device herein can provide a refrigerant charge reduction for example that is used in the chiller unit, while facilitating drainage out of the heat exchanger. The combination refrigeration displacement and drain device can alleviate the liquid refrigerant accumulation that may normally be necessary to induce flow in a gravity drain design.

A computer-implemented method, environmental control system (ECS) for an aircraft, and system are provided. Air temperatures at the inlet and outlet of a ram air duct for an ECS are measured. Also, air temperatures at outlets from one or more heat exchangers arranged in the ram air duct are measured. The temperatures are typically measured when the aircraft is on the ground and when aircraft engines supplying air to the ECS are operating at idle. Shortly thereafter, the heat exchangers are manually inspected to determine a level of actual fouling (e.g., dirt, dust, or other debris accumulated on heat exchanger surfaces). A supervised machine learning or other statistical analysis is performed on the measured temperatures and associated actual fouling levels to develop a model that predicts an amount of heat exchanger fouling, based on the temperature measurements. An alert can be output if the predicted fouling exceeds a fouling threshold. 1.

This invention is designed to create potentially unlimited commercial fresh water at a significantly reduced cost in relation to existing fresh water creation systems such as sea water desalination. This invention pumps coastal atmospheric air through sealed pipes to ocean water depths (ideally) of approximately 100-305 meters, or (ideally) into the local ocean's thermocline layer. Fresh water condensation occurs inside the sealed air pipes as cold ocean water chills the outside of the pipes. Condensation fresh water flows via gravity to the low point in the sealed air pipes where a powered fresh water pump is located. This powered fresh water pump then pumps the accumulated condensation water to the ocean surface and then on to shore as usable fresh water. The pumped-in air, now dehumidified, is piped to the surface and returned to the atmosphere. 1.

Принадлежит: Nippon Light Metal Co Ltd

Provided is a precoated fin material for heat exchangers that allows the construction of a fin structure in which frost formation at the time of heater operation can be prevented to the extent possible, and under such a condition that condensation is liable to occur on a fin surface, a water droplet of condensed water can be quickly removed by bringing the water droplet into contact with a hydrophilic film, and as a result, a favorable heat exchange function can be maintained without any increase in ventilation resistance. Also provided is a heat exchanger including such fin structure. The precoated fin material for heat exchangers includes: a fin substrate formed of an aluminum plate material; a crosslinked hydrophobic film having a frost formation-suppressing effect, the crosslinked hydrophobic film being formed on one surface of the fin substrate and being formed of an aqueous hydrophobic coating composition containing a resin (A) having a fluorine atom-containing group, a quaternary ammonium salt group-containing modified epoxy resin (B), and an amino resin (C) at predetermined ratios; and a hydrophilic film having a condensed water-removing effect, the hydrophilic film being formed on another surface of the fin substrate. The heat exchanger includes a fin structure in which a hydrophobic surface having a frost formation-suppressing effect and a hydrophilic surface having a condensed water-removing effect are opposite to each other.
