Abstract: A heating, ventilation, and air-conditioning (“HVAC”) system for use with a refrigerant. The HVAC system includes a compressor, a condenser, an expansion device, an evaporator, and a separator. The compressor is operable to compress the refrigerant. The condenser is positioned downstream of the compressor and operable to condense the refrigerant. The expansion device is positioned downstream of the condenser and operable to reduce a pressure of the refrigerant flowing therethrough. The evaporator is positioned downstream of the expansion device and operable to vaporize the refrigerant from the expansion device. The separator is positioned downstream of the expansion device and operable to separate the refrigerant into liquid refrigerant and gaseous refrigerant. The gaseous refrigerant from the separator and the liquid refrigerant from the separator are combined prior to being compressed by the compressor.

Abstract: A raw material gas liquefying device includes a feed line; a refrigerant circulation line; and a controller. In a refrigerant liquefaction route, a refrigerant flows through a compressor, a heat exchanger, a circulation system JT valve, a liquefied refrigerant storage tank, and the heat exchanger, and returns to the compressor. In a cryogenic energy generation route, the refrigerant flows through the compressor, the heat exchanger, an expansion unit, and the heat exchanger, and returns to the compressor. The controller determines if a refrigerant storage tank liquid level is within an allowable range, manipulates a feed system JT valve opening rate to control refrigerant temperature at the high-temperature-side refrigerant flow path exit side of the heat exchanger, and manipulates the opening rate of the feed system JT valve to control the refrigerant storage tank liquid level so that the refrigerant storage tank liquid level falls into the predetermined allowable range.

Abstract: An improved Bernoulli heat pump, wherein the intake section of a Venturi tube is structured so that when the refrigerant flows from the intake section into and through most of the middle (narrow) section, its flow is essentially laminar. Additionally, a second, bi-phase, component is added to the flowing gaseous refrigerant. Part of the bi-phase component evaporates, reaching super saturation, which state is maintained in the middle section, owing to the laminar flow, increasing heat absorption.

Abstract: A control method includes initially operating a compressor at the same RPM as an operating RPM of the compressor during a previous cycle, adjusting the RPM in consideration of an operation rate of the previous cycle such that the RPM is increased when the operation rate is greater than a first set value, reduced when the operation rate is less than a second set value, and maintained when the operation rate is within a range between the first set value and the second set value, and operating the compressor at the adjusted RPM, the first set value being greater than the second set value.

Abstract: A method for liquefaction of industrial gases or gas mixtures (hydrocarbon and/or non-hydrocarbon) uses a modified aqua-ammonia absorption refrigeration system (ARP) that is used to chill the gas or gas mixture during the liquefaction process. The gas may be compressed to above its critical point, and the heat of compression energy may be recovered to provide some or all of the thermal energy required to drive the ARP. The method utilizes a Joule Thomson (JT) adiabatic expansion process which results in no requirement for specialty cryogenic rotating equipment. The aqua-ammonia absorption refrigeration system includes a vapor absorber tower (VAT) which permits the recovery of some or all of the heat of solution and heat of condensation energy in the system when anhydrous ammonia vapor is absorbed into a subcooled lean aqua-ammonia solution. The modified ARP with VAT may achieve operating pressures as low as 10 kPa which results in ammonia gas chiller operating temperatures as low as −71 C.

Abstract: Embodiments of the present disclosure generally relate to heat transferring apparatuses and methods. The apparatus and methods utilize the Joules-Thompson effect to remove heat from a heat source to facilitate cooling of the heat source. In one example, an apparatus receives heat from an object to be cooled. The received heat is used to pressurize a fluid. The pressurized fluid is depressurized through a venturi using vapor pressure as a driving force, thus cooling the fluid.
