Marine battery cabin dehumidifier

Abstract

This utility model relates to a marine battery compartment dehumidifier. The compressor exhaust is sequentially split into two paths via a high-pressure switch and a high-pressure gauge. One path connects to a shell-and-tube condenser, which is externally connected to a cooling water inlet and outlet pipe. The condenser outlet then sequentially connects to a dryer filter and an expansion valve before connecting to an evaporator. The evaporator outlet then sequentially connects to a low-pressure gauge, a low-pressure adjustable switch, another low-pressure switch, and a safety valve before connecting to the compressor return gas. The other path sequentially connects to the compressor return gas via a bypass solenoid valve and an adjustable valve. A PLC panel with a built-in PLC controller is installed in the middle of the air conditioning unit on one side of the air outlet. Its structure is simple and compact, and it can adjust the dehumidification power consumption according to significant fluctuations in external temperature and humidity to meet dehumidification performance requirements.

Description

Technical Field

[0001] This utility model relates to a dehumidifier, specifically a marine battery compartment dehumidifier. Background Technology

[0002] With the gradual maturation of new energy technologies, electric vehicles, ships, and aircraft have been widely applied in various industries. On electric ships, due to the high humidity of the aquatic environment, high humidity in the battery compartment can easily affect battery safety and lifespan. However, due to the complex usage of batteries—different heating temperatures depending on whether they are not in use, operating at low or high power—the humidity in the battery compartment can fluctuate significantly. Currently, with the development of integrated central air conditioning systems in ships, the temperature control of the cooling compartments provided by the central air conditioning system cannot meet the dehumidification and high-precision humidity control requirements of the battery compartment. Summary of the Invention

[0003] This invention provides a marine battery compartment dehumidifier with a simple and compact structure that can adjust dehumidification power consumption according to large fluctuations in external temperature and humidity, thus meeting dehumidification performance requirements.

[0004] The technical solution adopted by this utility model is: a marine battery compartment dehumidifier, including an air conditioning unit, which houses a compressor, a sleeve condenser, an evaporator, and a fan. The air conditioning unit is characterized by being divided into upper and lower chambers. The compressor and sleeve condenser are arranged side-by-side in the lower chamber. An evaporator is inclinedly arranged in the lower part of the upper chamber. An air inlet is located on the side wall of the unit corresponding to the downward-sloping side of the evaporator. A temperature and humidity sensor and an air filter are installed on the air inlet. An electric heater is located in the middle of the upper chamber, and a fan is located in the upper middle part of the upper chamber. The upper part of the upper chamber is connected to the air inlet... An air outlet is provided on the side opposite to the air vent; the compressor exhaust is divided into two paths via a high-pressure switch and a high-pressure gauge. One path connects to a shell-and-tube condenser, which is connected to a cooling water inlet and outlet pipe. The exhaust from the shell-and-tube condenser is connected to the evaporator via a dryer filter and an expansion valve. The exhaust from the evaporator is connected to the compressor return gas via a low-pressure gauge, a low-pressure adjustable switch, a low-pressure switch, and a safety valve. The other path connects to the compressor return gas via a bypass solenoid valve and an adjustable valve. A PLC panel with a built-in PLC controller is installed in the middle of the air conditioning unit on the side of the air outlet.

[0005] The air outlet has an air outlet grille.

[0006] The electric heater is positioned above and below the evaporator.

[0007] Condensate outlet pipes are connected to both sides of the bottom of the air conditioning unit.

[0008] The PLC controller is connected to a remote control box.

[0009] A water pressure gauge is connected to the cooling water inlet pipe, and a water flow switch is connected to the cooling water outlet pipe.

[0010] The fan is a centrifugal fan.

[0011] The inner wall of the air conditioning unit is provided with a heat insulation layer.

[0012] The evaporator is connected to an expansion valve and then to a liquid separator for liquid distribution.

[0013] A temperature and humidity sensor is installed on the air outlet.

[0014] The beneficial effects of this utility model are:

[0015] 1. The compressor exhaust is connected to the compressor return gas via a bypass solenoid valve and an energy regulating valve, which can optimize the matching of cooling capacity and load, optimize energy consumption, and meet the cooling needs of batteries in the battery compartment under various operating conditions with large fluctuations in temperature, humidity and load.

[0016] 2. A liquid distributor is installed at the evaporator inlet to optimize the refrigeration distribution performance, improve the heat exchange efficiency of the evaporator, and play a role in saving energy and reducing consumption. At the same time, it can buffer the fluctuation of liquid delivery pressure, enhance stability, and cope with the frequent changes in temperature and humidity caused by the frequent changes from start-up to high power consumption when using battery-driven operation, thereby meeting the needs of use under conditions of frequent changes in refrigeration load.

[0017] 3. A low-pressure energy adjustment switch is set in the compressor return gas. By detecting the return gas pressure, the compressor operating status is dynamically adjusted to ensure stable return gas pressure and adjust the compressor power according to load temperature and humidity fluctuations, thereby reducing energy consumption. At the same time, it can further realize the dynamic matching of cooling capacity with actual needs, taking into account both energy efficiency improvement and the extension of the overall machine service life.
