Embodiment Construction
[0031] Below in conjunction with specific embodiment, further illustrate the present invention.
[0032] Due to the space-saving requirements of ships, electric heating air distributors are more commonly used in current ship air conditioners, because electric heating air distributors occupy a small area, are low in height, and are easy to use. The disadvantages are that they are relatively rough, and the temperature control accuracy is low. A type of switch that simply turns a heating element on or off.
[0033] The invention discloses a high-precision temperature control system for an electric heating air distributor for a ship's air conditioner. , the hot air duct is connected to the electric heating air distributor on the roof of each cabin, and is connected to the fan. There is an aisle connected to the cabin outside the cabin, and a circulating air return port is provided in the aisle to absorb the circulating hot air in the cabin. Return air, the circulating air return ...

The invention belongs to the field of marine air conditioners, and relates to electric-heating air distributers of marine air conditioners, in particular to a temperature control system for high-precision electric-heating air distributers of the marine air conditioners. The temperature control system is characterized in that the temperature control system comprises the electric-heating air distributers mounted at the tops of ship cabins; a vertical air outlet of each air distributor faces downwards, and a horizontal air return inlet of each air distributor is connected to a hot air pipeline; the hot air pipeline is communicated with the electric-heating air distributers at the tops of the ship cabins, and returns hot air to the ship cabins through an outlet of a marine air conditioner system; temperature controllers are arranged on the walls of the ship cabins, and a certain distance is kept between each temperature controller and the vertical air outlet of the corresponding electric-heating air distributer; each temperature controller comprises a temperature collection module used for collecting air humidity signals in the ship cabins or controlled regions; after receiving collected temperature voltage signals, single chip microcomputers of the temperature control modules calculate heating voltages needed by heating components of the electric-heating air distributers, and control to output the voltages to two ends of the heating components connected with the single chip microcomputers through controllable-silicon output circuits.
Description
technical field [0001] The invention relates to an electric heating air distributor for a ship air conditioner, in particular to a temperature control system and a temperature control method for a high precision electric heating air distributor for a ship air conditioner. Background technique [0002] Existing marine air conditioners mainly use electric heating air distributors, and the thermostats for temperature control of electric heating air distributors mostly use mechanical switches to control electric heating components, that is, by collecting indoor temperatures and comparing the set values, Output the on or off signal to the electric heating part. When the electric heating part is energized, it will be completely heated, and when the power is off, it will no longer be heated. Due to the large thermal inertia of the electric heating part, and only two kinds of control, heating and non-heating, lead to this This fast on-off two-position control has low precision, larg...
