In accordance with an embodiment of the invention, there is provided a method of warming a heat exchanger array of a very low temperature refrigeration system, the method comprising diverting at least a portion of refrigerant flow in the refrigeration system away from a refrigerant flow circuit used during very low temperature cooling operation of the refrigeration system, to effect warming of at least a portion of the heat exchanger array; and while diverting the at least a portion of refrigerant flow, preventing excessive refrigerant mass flow through a compressor of the refrigeration system.

A purchase of debt system ('PODS') and process that allows a debtor and entity using the system to financially benefit by exploiting the errors, fraud and inefficiencies contained in debts, such as medical bills. Specifically, the type of debt associated with, for example, medical bills is debt liability that has no asset(s) associated with it. The debtor is benefited by assigning the debt and associated liability, at a reduced price, to a third party (the entity using the system). The entity using the system then obtains a financial benefit by settling the debt, with the creditor, for an amount less than that paid to it by the debtor.

Aspects of the invention are found in a heat exchanger. The heat exchanger includes a fluid inlet manifold, a fluid outlet manifold, a plurality of heat transfer channels configured to communicate with the fluid inlet manifold and the fluid outlet manifold, and packing located within the fluid inlet manifold. Further aspects of the invention are found in a refrigeration system. The refrigeration system includes a compressor and at least one heat exchanger coupled to the compressor. The at least one heat exchanger includes a header, packing located in the header, and a heat transfer channel. The heat transfer channel is configured to receive fluid passing through the header and the packing.

Refrigerants containing HCFC's are replaced with new blends by using R-236fa and R-125, or R-125 with R-245fa, or R-236ea, or R-134a with R-236fa in place of HCFC's. No hardware or oil composition changes are required to maintain temperatures, pressures and capacity substantially unchanged in a refrigeration system.

Nonflammable mixed refrigerants (MR) for use with very low temperature throttle-cycle refrigeration systems

Refrigerant freezeout is prevented, and temperature is controlled, by the use of a controlled bypass flow that causes a warming of the lowest temperature refrigerant in a refrigeration system that achieves very low temperatures by using a mixture of refrigerants comprising at least two refrigerants with boiling points that differ by at least 50&#xb0; C. This control capability enables reliable operation of the very low temperature system.

Disclosed is an ultra-low temperature, dual-compressor (), recirculating gas chilling system that includes a closed-loop mixed-refrigerant primary refrigeration system () in combination with a closed-loop gas secondary refrigeration loop (). The ultra-low temperature, dual-compressor (), recirculating gas chilling system disclosed is capable of providing continuous long term chilled gas and fast cooling of a high or ambient temperature object (), such as a chuck used in processing semiconductor wafers or any such device. The gas chilling system is characterized by three modes of operation: a normal cooling mode, a bakeout mode, and a post-bake cooling mode.

A shell and coil type heat exchanger evaporator provides cooling for industrial coolants characterized by high viscosity and a poor heat transfer coefficient. A large heat transfer surface area is provided within a limited volume, and without a high coolant pressure drop. A short initial cool down period is provided due to minimized heat exchanger mass and minimized volume of liquid coolant in the heat exchanger during initial cool down.

Heating/defrost constructions of a very low temperature refrigeration system having a defrost supply circuit and a defrost return bypass circuit optimizing the heating/defrost cycle, preventing overload (excessive pressure) of its refrigeration process and protecting components from damaging temperatures. The defrost cycle operates continuously, when required, and provides a shorter recovery period between heating/defrost and cooling operating modes. The rate of the temperature change during cool down or warm up is controlled in an open loop fashion by controlled refrigerant flow in bypass circuits.

A standard refrigeration pressure regulating valve limits the minimum temperature produced by a refrigeration process, which uses a refrigerant mixture including at least two components whose normal boiling points differ by at least 50C. Limiting the lowest temperature prevents freezout of the individual refrigerant.
