Problems solved by technology
The atmospheric environment of the cabin is poor during the long-term submersion of the submarine, and the user experience is not good.
[0004] Most of the existing thermal comfort evaluations are based on the PMV-PPD index. The PMV (predicted mean vote)-PPD (predicted percent dissatisfied) index is currently the most widely used index for evaluating thermal comfort in the world, but this index system is only in the uniform It has good applicability in the steady-state environment, and cannot be directly applied to the thermal comfort design of the ventilation and air-conditioning system for multi-cabin and multi-functional spaces of submarines.

The invention relates to the technical field of ship ventilation air-conditioning system design, in particular to a thermal comfort design method for a submarine ventilation air-conditioning system. According to the thermal comfort design method of the ventilation air conditioning system suitable for the closed cabin space, the thermal comfort of the living environment of people can be improved on the basis of saving energy and improving the energy utilization rate; according to the method, the personnel activity space in the submarine cabin is partitioned, different design parameters are adopted for different regions, the thermal comfort design of the overall ventilation and air conditioning system of the submarine is achieved, the energy utilization efficiency is considered while the thermal comfort of all the partitions is guaranteed, and the habitability level of all the cabins in the submarine is improved; by establishing the simulation model and performing parameter calculation, the thermal comfort design scheme of each cabin of the submarine is evaluated and checked, and the submarine ventilation air-conditioning system is adjusted according to the checking result, so that the thermal comfort design accuracy of the submarine ventilation air-conditioning system is improved.
Description
technical field [0001] The invention relates to the technical field of ship ventilation and air-conditioning system design, in particular to a thermal comfort design method of a submarine ventilation and air-conditioning system. Background technique [0002] The atmospheric environment of submarine cabins has the characteristics of airtightness, comprehensiveness and settlement. For a long time, the air-conditioning system has been limited by the overall layout and energy consumption, and the control ability is limited. Therefore, the temperature and humidity in the cabin have been in a relatively high state for a long time, and the highest in individual cabins. The room temperature even exceeds 40°C and the relative humidity exceeds 95%. [0003] In the design process of the existing submarine ventilation and air conditioning system, only the temperature and humidity indicators are considered, and thermal comfort is not evaluated. The system function can only meet the funct...
