Thermal management system and operation method for a large deep-diving platform cabin

Abstract

A thermal management system for a large deep diving platform cabin. The structure of the mechanical compression refrigeration system includes a control box, the control box is connected to a fan and a compressor by electrical signals, and one end of the fan is connected in series with a heat coil, a cold coil and an evaporator. Both the hot coil and the cold coil are connected to the cooling water user and the cooling fresh water tank through pipelines, and the oil separator, compressor and liquid storage are connected between the evaporator and the condenser through pipelines; the structure of the fresh water cooling circulation system is : One end of the top of the cooling fresh water tank is connected to the cooling water user through a pipeline, the other end of the top of the cooling fresh water tank is connected to the heat coil through a pipeline, and one side of the cooling fresh water tank is connected to the condenser through two pipelines, One of the pipelines is equipped with No. 1 circulating water pump, No. 1 electric three-way water regulating valve and No. 2 electric three-way water regulating valve, and the other side of the cooling fresh water tank is equipped with an outboard heat exchange coil, which is reliable in operation and low in cost. It is beneficial to the noise control of the cabin.

Description

technical field [0001] The invention relates to the technical field of manned submersibles, in particular to a large deep-diving platform cabin thermal management system and an operating method thereof. Background technique [0002] Large-scale deep-diving platform is a large-scale mobile deep-diving equipment with deep-sea observation and operation capabilities. The large-scale deep-diving platform cabin is a closed cabin that integrates the work and living functions of personnel. The equipment in the cabin is dense, the space is compact, and the heat source is unevenly distributed, which is prone to harsh air environments such as high temperature and humidity. This not only affects the work efficiency of personnel, endangers the health of personnel, but also affects the reliability of equipment. [0003] At present, the deep submersibles in the prior art have short operation time and energy shortage, and do not have the ability to control the temperature and humidity in t...

This not only affects the work efficiency of personnel, endangers the health of personnel, but also affects the reliability of equipment

[0003] At present, the deep submersibles in the prior art have short operation time and energy shortage, and do not have the ability to control the temperature and humidity in the cabin with the change of the diving depth. A large amount of condensed water will appear on the bulkhead and equipment surface during the dive

Large-scale deep-diving platforms have more complex functions than small-scale deep-diving vehicles, with more personnel and longer continuous operation time. They need to be equipped with active temperature control systems to control the temperature and humidity in the cabin to meet comfort requirements and other functional requirements.
