Abstract: A refrigerant system control software upgrades are remotely downloaded over information carrying media. The software upgrades can be timed to occur when the Internet traffic is low. Once the upgrade has been received, a verification test may be performed for the refrigerant system components affected by the software upgrade. The test is monitored, and the results are sent back to the remote location such that the remote location can ensure the software upgrade was successful.

Abstract: A refrigerant vapor compression system includes a compression device, a heat rejecting heat exchanger, an economizer heat exchanger, an expander and an evaporator disposed in a refrigerant circuit. An evaporator bypass line is provided for passing a portion of the refrigerant flow from the main refrigerant circuit after having traversed a first pass of the economizer heat exchanger through the expander to partially expand it to an intermediate pressure and thence through a second pass of the economizer heat exchanger and into an intermediate pressure stage of the compression device. An economizer bypass line is also provided for passing a portion of the refrigerant from the main refrigerant circuit after having traversed the heat rejecting heat exchanger through a restrictor type expansion device and thence into the evaporator bypass line as liquid refrigerant or a mix of liquid and vapor refrigerant for injection into an intermediate pressure stage of the compression device. Both economizer and injection flows are mixed together prior to entering an intermediate compression point, when an economizer circuit is active. The invention allows for enhanced system performance and advanced discharge temperature control.

Abstract: A refrigerant system is provided with at least two sequential stages of compression. An intercooler is positioned intermediate the two stages. The refrigerant flowing through the intercooler is cooled by a secondary fluid such as ambient air. A vapor/liquid injection function is also provided for the refrigerant system. The intercooler function and the vapor/liquid injection function are selectively activated on demand depending on environmental conditions and thermal load in a conditioned space. This invention is particularly important for the CO2 refrigerant systems operating in the transcritical cycle.

Abstract: The present invention relates to a way of reducing the amount of energy required to partially compress a refrigerant in a compressor operating in a rapidly cycled unloaded mode. A valve on a suction line is closed when the compressor moves to the unloaded condition. In this manner, the amount of energy required to partially compress the refrigerant in the compressor, at the unloaded condition, is dramatically reduced.

Abstract: A refrigerant system operates with tandem compressors. As is known, one or more of the tandem compressors can be shut down at part-load operating conditions when lower refrigerant system capacity is required. A control periodically engages at least one shut down tandem compressor for a short period of time. This increases the refrigerant mass flow of refrigerant throughout the refrigerant system to ensure that oil travels through the system and is not retained in the system.
