Description

Technical Field

[0001] This utility model relates to the field of environmental control device technology, specifically a marine combined intelligent environmental control device. Background Technology

[0002] Currently, the modular air handling units commonly equipped on ships have a relatively simple structure and a limited range of air intake and supply methods, only meeting conventional design requirements. Such air handling units cannot guarantee a constant flow of fresh air, nor can they meet actual usage needs. For example, in the bridge of a common ship type, the conventionally designed airflow will cause the temperature to rise significantly during the day due to sunlight radiation. In this case, the conventionally designed airflow will not meet the needs, requiring the installation of separate cabinet or split-type air conditioners to meet the comfort requirements of personnel, thus increasing operating costs. Similarly, when personnel living quarters are located in the engine room, the heat generated by the main engine during operation will raise the inter-floor temperature, affecting the comfort of personnel.

[0003] Alternatively, if a variable air volume (VAV) air conditioning system is used, a chiller unit is required to provide chilled water and VAV terminals, which is not economically valuable and takes up a lot of space.

[0004] Therefore, marine-mounted combined intelligent environmental control devices are needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a marine combined intelligent environmental control device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A marine-grade modular intelligent environmental control device includes a base, a compressor mounted on the outer wall of the base, a condenser mounted on the outer wall of the base, an oil separator mounted on the outer wall of the base, a dryer filter mounted on the outer wall of the base, an air conditioning unit mounted on the outer wall of the base, an air outlet box mounted on the outer wall of the air conditioning unit, and an electrical control box mounted on the outer wall of the base.

[0008] As a preferred embodiment of this utility model, an expansion valve, an air filter, a fresh air induced draft fan, an evaporator, a heater, a humidifier, a water baffle, and a variable frequency circulating fan are respectively installed on the inner wall of the air conditioning unit.

[0009] As a preferred embodiment of this utility model, the air outlet box, the electrical control box, and the air conditioning unit are connected by bolts.

[0010] As a preferred embodiment of this utility model, it also includes an inter-floor temperature sensor and an electric air valve, wherein the inter-floor temperature sensor is suspended between each floor and is connected to the electrical control box via a connecting wire, and the electric air valve is installed at the air outlet of the fresh air induced draft fan.

[0011] In a preferred embodiment of this invention, the compressor is located on one side of the condenser, and the oil separator is located on one side of the condenser.

[0012] As a preferred embodiment of this utility model, the drying filter is located on one side of the oil separator, the air conditioning unit is located on one side of the drying filter, and the expansion valve is located on one side of the air filter.

[0013] As a preferred embodiment of this utility model, the electrical control box is located on one side of the air conditioning unit, the fresh air induced draft fan is located on one side of the air filter, and the evaporator is located on one side of the fresh air induced draft fan.

[0014] As a preferred embodiment of this utility model, the heater is located on one side of the evaporator, the humidifier is located on one side of the heater, the water baffle is located on one side of the humidifier, and the variable frequency circulating fan is located on one side of the water baffle.

[0015] Through the above technical solution, the interlayer temperature sensor feeds back the interlayer temperature to the electrical control box. The electrical control box uses PID to calculate the speed of the variable frequency circulating fan and the opening degree of the electric air valve based on the difference between the interlayer temperature and the set value.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the inter-layer temperature is fed back to the electrical control box through the inter-layer temperature sensor. The electrical control box calculates the speed of the variable frequency circulating fan and the opening degree of the electric air valve based on the difference between the inter-layer temperature and the set value using PID, thereby meeting the air volume requirements of the cabin and improving the living environment of the crew. This helps to solve the problems of the conventional air handling equipment on existing ships having a single air intake / supply, failing to guarantee a constant fresh air supply, failing to meet actual usage needs, and making the use of a variable air volume air conditioning system uneconomical.
