Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] Such as figure 1 As shown, the marine accurate temperature control refrigeration device of the present invention includes a first refrigeration compression condensing unit, a second refrigeration compression condensing unit, a cold storage 21, a gas collecting header 15, a liquid supply header 16 and a hot gas bypass valve 9. The first refrigeration compression condensing unit includes a first compressor 1, a first gas-liquid separator 6 and a first oil-gas separator 3, and the cold storage 21 has a refrigeration port C and an air return port B. The outlet of the first compressor 1 is connected with the inlet of the first oil-gas separator 3, the outlet of the first oil-gas separator 3 is connected with the main liquid supply pipe 16, and there is a first oil-gas separator 3 and the main liquid supply pipe 16. A condenser 4, a first outlet check valve 11...

The invention relates to a ship and warship assembly, in particular to a marine precise temperature control cold storage device. The marine precise temperature control cold storage device comprises afirst refrigeration, compression and condensation unit, a refrigeration house, a gas collection main pipe and a liquid supply main pipe. The first refrigeration, compression and condensation unit comprises a first compressor, a first gas-liquid separator and a first oil-gas separator. The first compressor is connected with the first oil-gas separator. The first oil-gas separator is connected withthe liquid supply main pipe, and a first condenser is arranged between the first oil-gas separator and the liquid supply main pipe. The first compressor is connected with the first gas-liquid separator, and the first gas-liquid separator is connected with the gas collection main pipe. A refrigeration opening of the refrigeration house is connected with the liquid supply main pipe, and a gas returnopening of the refrigeration house is connected with the gas collection main pipe. The marine precise temperature control cold storage device is characterized in that a hot gas bypass valve is further included, and the first oil-gas separator is connected with the hot gas bypass valve. The hot gas bypass valve is connected with a pipeline between a low-pressure pressure sensor and the gas collection main pipe. The oil shortage phenomenon cannot happen to the compressor of the precise temperature control cold storage device, and the service life is long.
Description
Technical field [0001] The invention relates to a ship component, in particular to a ship-used accurate temperature control refrigeration device for refrigerating and preserving food on ships, and is particularly suitable for fruits and vegetables. Background technique [0002] In food preservation technology, ensuring a constant storage temperature is the prerequisite and basis for ensuring food storage. [0003] At present, the marine precision temperature control refrigeration equipment used in the industry includes refrigeration compression and condensing units, cold storage, gas collection headers and liquid supply headers.
