A system for creating rink ice and utilizing high-temperature heat generated when creating rink ice, the rink ice being created by spraying water over a base material layer and flowing cold brine through cooling tubes embedded in the base material layer includes: a heat pump performing a refrigerating cycle using CO2 as a refrigerant for producing cold brine and hot water, and a means for introducing the brine which has worked to freeze the water sprayed over the base material layer and received heat from the water sprayed over the base material layer and the ice created to the heat pump, thereby the hot water is produced by the heat pump by using heat contained in the brine introduced to the heat pump as a heat source and the brine deprived of the heat in the heat pump is returned to the cooling tubes to be used as the cold brine, thus the cold brine for creating the rink ice and cooling the ice layer created and the hot water to be used in ancillary facilities of the ice-skating rink facility are produced.

Abrégé

A liquid injection type screw compressor in which, in a compression stroke of an working space formed by male and female rotors, liquids such as oil or water is prevented from leaking from the high pressure working space to a gas inlet side, suction resistance of gas sucked from the gas inlet to a rotor casing is reduced to improve volumetric efficiency, and shape forming of the casing is simplified. The liquid injection screw compressor has the male and female rotor pair of screw rotors, the rotor casing (1a, 1b) having a bore for receiving the rotors, a gas suction opening and a gas outlet that are provided in both end sections of the casing and communicate with the bore, and a lip section (4) projected from a bore surface (2) positioned more on the upstream side than a suction seal line (5) of the casing in order to prevent a back flow of the liquid from the bore surface toward the gas inlet side. The lip section (4) is positioned in a region surrounded by the suction seal line (5) and a line separated by a distance of one screw pitch of the rotors from the suction closure line (5) to the suction opening side.

Abrégé

A continuous transfer type freezer for cooling or freezing articles such as foodstuffs transferred on a conveyor belt by spraying chilled air from slit nozzles on the articles is provided in which chilled air jets rectified to have long spray travel is produced, thin stream layer of chilled air is formed on the surface of the article to achieve increased heat transfer, and exhaust passages of the chilled air are formed such that they do not affect the cooling function. A plurality of slit nozzles 5a, 6a are apposed above and under the conveyor belt along the belt transfer direction, each of the nozzles 5a, 6a is shaped such that it has an angled and succeeding parallel entrance way so that the chilled air is rectified in the entrance ways and spout from the nozzle opening at large velocity, and exhaust passages 12 are formed between each of the slit nozzles such that the chilled air spouted from the nozzles flows toward both lateral end sides of the conveyor belt 2.

Abrégé

An ammonia/CO2 refrigerating system having a liquid pump for feeding the liquid CO2 cooled in a brine cooler by the utilization of the vaporization latent heat of ammonia in an ammonia refrigeration cycle to a cooler, which comprises a liquid receiving vessel 4 for receiving a CO2 brine cooled in a brine cooler 3, a liquid pump 5 capable of changing the rate of the feed of a liquid, a rising piping 90 provided between the liquid pump 5 and a cooler 6, and a communication pipe 100 for communicating the top of the riser pipe 90 with the CO2 gas phase in the liquid receiving vessel 4, wherein the discharge pressure of the liquid pump 5 is set so as for the CO2 recovered form the cooler 3 or the liquid receiver 4 in the state of a liquid or a gas-liquid mixture, and the level of the rise in the rising piping 90 is set at a level being the same as or higher than the highest storage level for the CO2 brine in the liquid receiving vessel4. The above ammonia/CO2 refrigerating system allows a refrigeration cycle of a combination of an ammonia cycle and a CO2 cycle to be formed with no care, even when a refrigerating showcase, which is the cooler side of the CO2 cycle, is installed at an arbitrary place.
