Air conditioner and marine air-conditioning system

Abstract

The invention provides an air conditioner and a marine air-conditioning system. According to the air conditioner, a box body is provided with a fresh return air mixing cavity and a fresh inlet air cavity and is also provided with a fresh air inlet communicated with the fresh inlet air cavity and a return air inlet communicated with the fresh return air mixing cavity, and the fresh inlet air cavityis communicated with the fresh return air mixing cavity. A fresh air fan is arranged in the fresh inlet air cavity. A fresh inlet air regulating valve is arranged at the fresh air inlet and controlsfresh inlet air amount. A return inlet air regulating valve is arranged at the return air inlet and controls return inlet air amount. A detection control portion comprises an air amount detecting assembly and a control assembly, wherein the air amount detecting assembly is arranged in the fresh inlet air cavity and detects the fresh air inlet amount of the fresh inlet air cavity, the control assembly is connected with the fresh inlet air regulating valve, the return inlet air regulating valve and the air amount detecting assembly, and the opening degrees of the fresh inlet air regulating valveand the return inlet air regulating valve are controlled according to the fresh inlet air amount detected by the air amount detecting assembly. The air conditioner is more accurate in fresh inlet airamount control.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an air conditioner and a marine air conditioning system. Background technique [0002] Compared with ordinary land buildings, ships are a more closed and compact space. The living quarters of ships have very high requirements for air quality (fresh air volume), and the energy consumption of fresh air accounts for the total energy consumption of ship air-conditioning systems with all-air systems. 1 / 3, so the fresh air volume can be changed according to the different operating conditions of the air conditioning unit (such as cooling, heating or ventilation), and the fresh air volume can be precisely controlled, which directly affects the energy consumption of the ship's air conditioning and the air quality of the crew's living environment . [0003] The following is a brief description of the suitable fresh air volume for different operating conditions of air-conditioning...

AI Technical Summary

Problems solved by technology

However, it is very difficult to determine the static pressure sampling measurement point in the mixing tank of this scheme, because it is not easy to find a stable static pressure measurement position in the volume of the mixing tank due to the economical and compact size of the ship. Changes in the construction of the new return air pipe network will also have an irregular impact on the static pressure of the measuring point, and it is necessary to re-measure and correct the measuring point to ensure the accuracy of the fresh air volume measurement of the project

[0008] In addition, the air-conditioning box of this scheme does not take into account the new connection of the unit and the characteristics of the return air pipe network. The pipe resistance is very large, and the automatic adjustment of the return air valve alone cannot meet the accuracy requirements of fresh air volume control
