Marine full-pressure air cooler capable of automatically controlling temperature and humidity

Abstract

The invention provides a marine full-pressure air cooler capable of automatically controlling temperature and humidity. An electric adjusting valve and a PLC control module with a temperature and humidity sensor are adopted for automatically regulating the requirement for the environment temperature and humidity. An umbrella-shaped waterproof pressure-regulating balance pipe with a support and a regulating valve assembly with a branch pipe act together to regulate the internal pressure of a condensate water drainage system under the positive and negative pressure working conditions. A condensate water drainage pipeline with a small water return bend is adopted, so that raw materials are saved, and the labor efficiency is improved. A double-layer water channel end cover is formed by casting, and high-point deflation and low-point drainage are designed at the bottom of the double-layer water channel end cover. The space environment temperature and humidity are automatically regulated. The small water return bend is rapidly filled with condensate water generated when high-temperature and high-humidity air passes through the full-pressure air cooler, and the condensate water drainage system regulates the internal pressure of the air cooler and the internal pressure of the drainage pipeline under the combined action of the umbrella-shaped waterproof pressure-regulating balance pipewith the support and the regulating valve assembly with the branch pipe. The air cooler is suitable for ship engineering.

Description

technical field [0001] The invention provides a marine air cooler, especially an air cooler suitable for various positive and negative pressure systems and the temperature and humidity control of large, medium and small independent spaces. Specifically, it is a marine full-pressure air cooler with automatic temperature and humidity control. Background technique [0002] The ambient temperature of the product space of the ship is related to the flow rate of the refrigerant water of the air cooler and the use of the fan. The size of temperature and humidity. The outlet valve of the air cooler of the existing product is a manual cut-off valve, which has the problem of being often switched by people, and it is difficult to ensure the requirements of the ambient temperature and humidity; and the fans are installed on both sides of the air cooler, which are divided into positive pressure air coolers and negative pressure air coolers Two forms, while the air cooler condensate dis...

Problems solved by technology

The outlet valve of the air cooler of the existing product is a manual cut-off valve, which has the problem of being often switched by people, and it is difficult to ensure the requirements of the ambient temperature and humidity; and the fans are installed on both sides of the air cooler, which are divided into positive pressure air coolers and negative pressure air coolers Two forms, while the air cooler condensate discharge adopts the method of installing a water return bend in the discharge pipeline. This solution cannot adjust the internal pressure of the negative pressure air cooler discharge system and prevents the refrigerant water from being released, resulting in a huge loss Potential safety hazard; the return water bend is made by pouring sand into the copper pipe after annealing, and there are many overlapping parts, so the production of a large number of return water bends wastes raw materials and consumes a lot of man-hours; the high point of the air cooler is usually designed in the In the upper left corner or upper right corner of the air cooler, the high point bleed internal thread joint is connected to the bleed pipeline with a stop valve through a transition joint. If the air cooler is installed in the corner of a cabin, the high point bleed joint will break or leak However, due to the narrow space in the corner, it is difficult for personnel to perform construction, so the air cooler has to be disassembled, and the broken joints or leaks are taken out before installation, which increases a lot of workload

[0003] Therefore, the existing technical solutions cannot solve the above four problems of the air cooler
