Description
Technical Field
The utility model relates to an air conditioning system, a marine variable water volume air conditioner system specifically says so.
Background
In the existing air conditioning and ventilating system for large ships, indirect constant air conditioning systems (which means a water chilling unit and an air conditioner are configured) are a constant water volume air conditioning system and a constant air volume air conditioning system or a variable air volume air conditioning system. When the air-conditioning system with the fixed water flow runs, an electric three-way valve, a fixed-frequency refrigerant water pump and a fixed-frequency cooling water pump are used for controlling an air conditioner at the tail end and a fan coil, and the water flow is a water pipe which is selected and matched according to the maximum water flow calculated by load no matter the refrigerant water flow or the cooling water flow. Because the load is changed in one day or in the whole process of summer, the load is also changed continuously, when the load is changed continuously, the refrigerant water pump and the cooling water pump are operated with the maximum water quantity all the time, the waste is more waste in the operation process of the air conditioning system, and the waste is more serious in the air conditioning system of a large ship.
Disclosure of Invention
In order to solve above current water ration system operation and continuously reduce the time there is extravagant phenomenon in load, the utility model provides a simple structure, frequency conversion control, energy saving and consumption reduction's boats and ships variable water volume air conditioning system.
The utility model adopts the technical proposal that: the utility model provides a marine variable water volume air conditioner system, includes cooling water set and a plurality of marine air conditioner which characterized in that: a cooling water inlet pipe on one side of cooling water of the water chilling unit is provided with a variable-frequency cooling water pump, one side of refrigerant water of the water chilling unit is connected with a water separator, the water separator is respectively connected to a plurality of marine air conditioners through a plurality of control valves in a liquid inlet mode, the plurality of marine air conditioners are connected to a water collector in a liquid return mode, and the water collector is connected to one side of the refrigerant water of the water chilling unit through the variable-frequency refrigerant water pump in a return mode; and a pressure difference sensor is connected between the water separator and the water collector, the water separator and the water collector are communicated through an electric regulating valve, and the pressure difference sensor controls a variable-frequency cooling water pump, a variable-frequency refrigerant water pump and the electric regulating valve through a PLC (programmable logic controller).
Furthermore, the water collector is connected with one side of the cooling medium water of the water chilling unit through a filter, an expansion water tank and a variable-frequency cooling medium water pump.
Furthermore, the water chilling unit is of a double-unit parallel structure.
Further, a discharge valve is arranged below the water collector or on the rear connecting pipeline.
When the load of the air conditioner at the tail end is reduced, if the pressure difference detected by the pressure difference sensor between the water collector and the water separator is larger than a set value, the PLC controller controls the frequency of the variable-frequency cooling water pump and the variable-frequency refrigerant water pump, so that the power of the water pump is reduced, the energy consumption is reduced, the cooling water quantity is matched with the load variable frequency of the whole system, and the power of the cooling water pump is also reduced. Under the condition that the load is extremely reduced, the cooling and refrigerant water pump is reduced to the lowest frequency, and the PLC controller controls and starts the electric regulating valve between the water collector and the water distributor, so that the use safety of the valve of the whole system is protected. The system has more obvious energy-saving effect in a large-scale ship air-conditioning system, particularly in an area with a larger air-conditioning area.
