摘要： A multiple circuit refrigerant system includes a single economizer heat exchanger utilized for each of at least two circuits. The use of the single economizer heat exchanger reduces the cost of adding an economizer cycle, and further reduces other associated costs. Additionally, heat exchanger and overall system performance is enhanced further. Embodiments show the inclusion of two, three and four circuits, although greater numbers may also benefit form this invention.

摘要： In an air conditioning system including a compressor, a condenser, and an evaporator, a process includes the steps of feeding discharged refrigerant from the compressor to the condenser so as to provide a condensed refrigerant flow; splitting the condensed refrigerant flow into a main flow and an auxiliary flow wherein the auxiliary flow includes between about 8 and about 12% wt. of total mass flow rate of the condensed refrigerant flow; reducing temperature and pressure of the auxiliary flow so as to provide an economizer flow; passing the economizer flow and the main flow through a heat exchanger so as to provide a sub-cooled main flow and an economizer discharge flow; feeding the economizer discharge flow to the compressor; and feeding the sub-cooled main flow through the evaporator to the compressor. The system and process in accordance with the present invention advantageously allow for parameter optimization, circuit combination, and performance improvement through integration of economized and non-economized circuits.

摘要： A refrigerant system is operable in either heating mode or cooling mode. The system is also provided with an economizer cycle that will function in either heating mode or cooling mode. A four-way valve assembly selectively communicates refrigerant from either an indoor heat exchanger or outdoor heat exchanger to an economizer heat exchanger. The valve assembly further includes a restriction for restricting a refrigerant flow downstream of the economizer heat exchanger. The valve assembly provides two distinct restrictions such that a different size restriction is presented to the flow in cooling and heating modes. In this way, a single valve assembly can provide both the required routing for the alternative heating and cooling modes, and at the same time allow for distinct restriction sizes for the two modes without the necessity of separate expansion devices, also improving overall system cost and reliability.

摘要： A refrigerant system is provided with a variable speed drive for at least one of its fluid-moving devices, wherein the variable speed drive is provided by an automated mechanical drive. In the disclosed embodiment, one of the pulleys for driving the fluid-moving device has a variable diameter to vary the speed at which the fluid-moving device is driven.

摘要： An expansion device for the heat pump applications consists of a flow resistance device that has a different resistance to refrigerant flow depending on the flow direction through this device. The flow resistance device has no moving parts so that it avoids the damage, wear and contamination problems of the moveable piston in the prior art. The flow resistance device is a fixed obstruction about which the fluid must flow when traveling through the expansion device.

摘要： Refrigerant is circulated through a vapor compression system including a compressor, a condenser, an expansion device, and an evaporator. Cold condensate forms on the evaporator surfaces as the refrigerant accepts heat from an air stream. The cold condensate drips down from the evaporator coil and collects in a condensate pan. In one example, the cold condensate is directed into a condensate heat exchanger to subcool the refrigerant exiting the condenser. In another example, the refrigerant exiting the condenser flows through a refrigerant line located in the condensate pan. In another example, the cold condensate is sprayed on the refrigerant line exiting the condenser or on the subcooling portion of the condenser. By utilizing the condensate for further subcooling of the refrigerant, system capacity and efficiency are enhanced. Various control techniques and condensate flow methods are also disclosed.

摘要： An air conditioning or refrigeration system includes an expansion device that has a plurality of operating positions. When the expansion device is in a fully open position, the expansion device provides an indication to a system controller regarding that position. The controller responsively determines if the fully open position of the expansion device is caused by an undesirably low amount of refrigerant charge in the system. In one example, the controller rules out other possible reasons for the expansion device being in the fully open position. In one example, the controller automatically shuts down appropriate portions of the system to avoid any component damage that may result from having too low refrigerant amount in the system.

摘要： A method for operating a vapor compression system includes the steps of providing a vapor compression system having a compressor circuit including a compressor having an inlet port and an outlet port, a circuit incorporating the compressor, a condenser, an evaporator and an expansion device for sequentially generating a cooling refrigerant for cooling a stream of air so as to provide a dehumidified cooled stream of air, and a reheat refrigerant for heating the dehumidified cooled stream of air to provide a reheated dehumidified stream of air; controlling discharge pressure from the compressor outlet so as to increase discharge pressure from the compressor outlet. Furthermore, system dehumidification performance is improved in terms of latent capacity boost, undesired sensible capacity reduction, latent efficiency enhancement, and recovery of supply air temperature to a desired level.

摘要： A refrigerant cycle is provided with an economizer circuit. The amount of refrigerant passing through the economizer circuit can be gradually modulated by an expansion device whose position can be easily adjusted from fully open to fully closed or disengaged. In the past, economizer circuits have either been fully engaged or fully disengaged. Modulation of economizer flow allows for variable capacity operation. This improves unit operating efficiency, minimizes unit cycling and prevents compressor overloading at extreme of operating conditions. It also allows for head pressure and discharge temperature control.
