An insulation board includes a body; first bulges, disposed on the body and extending toward a first direction; and second bulges, disposed on the body and extending toward a second direction, and the first bulges and the second bulges are staggered, and the first direction is opposed to the second direction.

A heat shielding member includes a base, and a heat shielding membrane on the base.

The heat shielding membrane includes a porous layer including at least a closed pore. The porous layer includes resin and carbon-based filler. The heat shielding member has both of low thermal conductivity and low heat capacity and improves the fuel economy performance.

A modular, aerogel-based vacuum insulated pipe section comprising an outer conduit; an inner conduit concentrically disposed within the outer conduit with aerogel insulation and a condensable gas being disposed in the insulation space between the concentric conduits. As a stand-alone pipe section, the insulation space is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit, the condensable gas condenses and the pressure within the insulation space is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section further includes a coupling arrangement disposed on a first end of the inner conduit and a second end of the inner conduit, the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate, and a heat resistance unit comprising at least one radiation resistance sheet that blocks radiation heat transfer in the vacuum space so as to reduce heat transfer between the first plate and the second plate. The support includes two support plates, and the at least one radiation resistance sheet is supported by at least one support protrusion provided on a bar, which couples the two support plates to each other, to maintain an interval between the first plate and the second plate.

One aspect of the invention provides a composite refrigeration line set including: a suction line and a return line. One or more of the suction line and the return line are a composite refrigeration line set tube including: an inner plastic tube; a first adhesive layer circumferentially surrounding the inner plastic tube; an aluminum layer circumferentially surrounding the first adhesive layer and coupled to the inner plastic tube via the first adhesive layer; a second adhesive layer circumferentially surrounding the aluminum layer; and an outer plastic layer circumferentially surrounding the aluminum layer coupled to the aluminum layer via the second adhesive layer. The inner plastic tube is polyethylene of raised temperature. The outer plastic tube is polyethylene of raised temperature. The aluminum layer includes an alloy selected from the group consisting of: AL 3004-O, AL 3005-O, and AL 3555-O. The aluminum layer is butt-welded to itself.

Recent progress in passive radiative cooling technologies have significantly improved cooling performance under direct sunlight. Performance of existing passive radiative coolers for air conditioning and portable refrigeration applications can be improved with a material that is solar reflective and infrared transparent that can also have a low thermal conductivity.
