A compressor module (1) comprises: a floor member (3); a gas cooler (24) mounted on the floor member (3); a compressor skid (10) disposed on a side of the gas cooler (24) opposite to where the floor member (3) is located, the compressor skid (10) being connected to the gas cooler (24); and a leg portion (15) connected to the compressor skid (10) and fixed to the floor member (3) that supports the compressor skid (10), the leg portion (15) providing a gap to dispose the gas cooler (24) between the floor member (3) and the compressor skid (10).

Disclosed is an integrated compressor system configured to be integrated with existing air conditioning systems. The integrated compressor system generally includes a mounting assembly, a first compressor and a valve. The mounting assembly can be mounted directly on a condenser of an existing air conditioning system. The first compressor and the valve are mounted directly on the mounting assembly. The valve has a first valve inlet, a second valve inlet and a valve outlet. When assembly and integrated with an existing AC system, the first valve inlet is fluidly coupled to a compressor outlet of the first compressor, the second valve inlet is fluidly coupled to a compressor outlet of the compressor of existing AC system, and a valve outlet is fluidly connected to a condenser inlet of the condenser.

A device is provided for supplying heating and cooling, the device having a heat transfer medium arranged in the interior of a storage tank and having at least one cycle process plant operated using a working substance. The heat transfer medium has a lower temperature in a bottom region of the interior than in a region of the interior arranged thereabove. All the components of the cycle process plant that contain the working substance are arranged in the interior. The components of the cycle process plant arranged inside the storage tank are surrounded by the heat transfer medium. The heat transfer medium has constituents to bind or convert the working substance. The amount of the constituent as a proportion of the heat transfer medium is dimensioned in such a way that the working substance contained in the cycle process plant can be completely bound or converted by the constituent after an escape from the cycle process plant.

An apparatus includes a conduit coupled to a suction header that is configured to receive a refrigerant and an oil separator that is configured to separate an oil from the refrigerant received from a compressor. During a first mode of operation, the conduit is configured to remove excess oil from the refrigerant that has collected at the suction header. During a second mode of operation, the oil separator is configured to direct to the conduit the oil separated from the refrigerant received from the compressor. The conduit is configured to direct to an oil reservoir the oil from the oil separator and the excess oil removed from the refrigerant.

A packaged, pumped liquid, recirculating refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated in a pre-packaged modular machine room, and in which the condenser is mounted on the machine room and the evaporator is close coupled to the pre-packaged modular machine room. Prior art large receiver vessels may be replaced with a single or dual phase cyclonic separator also housed in the pre-packaged modular machine room.

A system including a pump, a boiler coupled to the pump, a turbine coupled to the boiler, a two-phase expander coupled to the turbine, and a condenser coupled to the two-phase expander and the pump.

Provided herein are compact chiller and cooler apparatuses, devices and systems. Chiller apparatuses disclosed herein can comprise a refrigeration system contained in a central housing with an external heat exchanger or “cold finger” configured to be universally applicable to coding various sizes and configurations of water baths and laboratory applications needing a cooling capacity. Chiller apparatuses disclosed herein are configured to be universally used with rotary evaporators, vacuum ovens, centrifugal concentrators and freeze dryers.

A cooling device having a vaporizer for vaporizing a working liquid, wherein the working liquid is held on a vaporizer bottom; a compressor for compressing a vaporized working liquid, wherein the compressor is configured to convey the vaporized working liquid from the bottom to the top in a setup direction; a liquefier having an upper wall configured such that the vaporized and compressed working liquid is condensable at the upper wall and drips down from top to bottom; and an intermediate bottom configured to collect a dripped-down working liquid, wherein the intermediate bottom comprises at least one opening through which the dripped-down working liquid may reach the vaporizer bottom.

A heat pump, having: an evaporator for evaporating a working liquid; a liquefier for condensing a compressed working vapor; a compressor motor with a suction mouth having attached thereto a radial impeller to convey a working vapor evaporated in the evaporator through the suction mouth; a guide space arranged to guide a working vapor conveyed by the radial impeller into the condenser; and a cooling device for cooling the guide space or the suction mouth with a liquid, wherein the cooling device is configured to guide the liquid onto an outside of the guide space or of the suction mouth, wherein the outside is not in contact with the working vapor, and wherein an inside of the guide space or of the suction mouth is in contact with the working vapor.

A packaged, pumped liquid, recirculating refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated in a pre-packaged modular machine room, and in which the condenser is mounted on the machine room and the evaporator is close coupled to the pre-packaged modular machine room. Prior art large receiver vessels may be replaced with a single or dual phase cyclonic separator also housed in the pre-packaged modular machine room.
