Abstract: This evaporator (12) is constructed such that bundles of heat exchanger tubes (15) for flowing cold water are disposed inside the container (14) for admitting the cooling medium. When a total cross sectional area of the heat exchanger tubes (15) at various locations in the flow direction of the cold water is compared, the total area in a downstream location is less that a total area in an upstream location of the flow passage. Therefore, even though the temperature differential between the cold water and the cooling medium is small, the flow speeds of the cold water in the downstream tubes become faster than that in the upstream tubes, so that the heat flux is increased and heat transfer rate is improved even in tube group D.

Abstract: A refrigerant system selectively operable in a cooling mode, a reheat cooling mode, and a heating mode, includes a primary heat exchanger and a reheat heat exchanger that condition air for a room. In the cooling mode, the primary heat exchanger functions as an evaporator that cools the air, while the reheat heat exchanger is inactive.

In the heating mode, the primary heat exchanger functions as a condenser that heats the air, while the reheat heat exchanger is inactive. When the reheat heat exchanger is inactive, a unique venting arrangement prevents the inactive heat exchanger from becoming flooded with liquid refrigerant.

Abstract: A refrigeration system having compressors positioned higher than the dispersed evaporators requires multiple suction risers. To better ensure oil return to the compressors, only a single oil return riser is employed. This oil return riser is connected to one end of an oil collection main positioned near the lower portion of the suction risers. The oil collection main is connected by restricted oil drain conduits to the lower portions of the suction risers, thereby collecting the oil which failed to be conveyed to the top of the suction risers by their vapor velocity. The restrictions in the oil drain conduits ensure adequate vapor velocity within the oil collection main even with widely varying loads on the suction risers.

Abstract: A dual (or multi) sectional evaporator system comprising first and second (or more) evaporator sections capable of cooling the air supply through the evaporator.

However, the warmest refrigerant passes through the first evaporator section and the coldest refrigerant passes through the second evaporator section (or last evaporator section if more than two sections), such that the air supply is precooled prior to reaching the second (or last) evaporator. Providing a two (or more) passes of refrigerant through the dual (or multi) sectional evaporator system increases the superheat temperature out of the first evaporator up to about 25 degrees Fahrenheit, and/or increases the mass flow of refrigerant because of the increased heat exchange efficiency provided by counterflow heat exchange.

Abstract: A refrigerant evaporator constructed by laminating a plurality of tube elements and a flat tube element. A second refrigerant passage in the flat tube element is disposed at a position being closest to a refrigerant outlet pipe. In the second refrigerant passage, some ribs are formed such that the ribs protrude from a flat plate connected to a metal plate to construct the flat tube element. The second refrigerant passage is partitioned into several small refrigerant passages. By this, the refrigerant flow area of the second refrigerant passage is smaller than that of the other refrigerant passages. That is, the refrigerant flow resistance of the second refrigerant passage is larger than that of other refrigerant passages. Accordingly, the refrigerant is prevented from flowing into the second refrigerant passage of the flat tube element.

Abstract: A cooling apparatus for use in a cooling system. The cooling apparatus has many evaporators disposed transversely to a longitudinal direction of a cool air duct. The refrigerant is supplied respectively to the evaporators by a valve device. Each evaporator has a conductive pipe which is wound spirally. Many blowers are disposed to each of the evaporators respectively. The diameter of wound part of the conductive pipe increases gradually along the circulating direction of the cool air, so the evaporators substantially have cone-shapes. Many defrosting heaters are disposed coaxially with the conductive pipes respectively. Since the evaporators are controlled respectively, at least one evaporator is operated during the defrosting operation of other evaporators, so the cooling efficiency is increased. Also, the heat exchange is performed uniformly on the entire areas of the evaporators by the spirally wound conductive pipes, the cooling apparatus has high efficiency of cooling.

Abstract: An air conditioner employs a non-azeotropic refrigerant mixture without deteriorating the heat-exchange efficiency and air-conditioning capability of an indoor heat exchanger of the air conditioner. The indoor heat exchanger (3) has a fin on which a first path (33), a second path (34), and a third path (35) for passing the refrigerant mixture are arranged. The first path passes the refrigerant mixture from the leeward side toward the windward side of an air flow produced by an indoor fan (7), to form a counterflow of the refrigerant mixture against the air flow. The second path passes the refrigerant mixture from the windward side toward the leeward side of the air flow. Although the second path forms a parallel flow of the refrigerant mixture with respect to the air flow, it achieves moderate heat-exchange efficiency because the number of rows of piping on the leeward side is greater than that on the windward side and because the rows of piping do not overlap one another with respect to the air flow.
