Abstract
The utility model discloses a variable-frequency air conditioning device of a ship, which is composed of an executing part, a controlled object, a sensing part, a comparing unit and a controller, wherein the sensing part comprise an evaporator; a water outlet pipe and a water returning pipe of the evaporator transmit a temperature change signal of the controlled object, namely coolant water, to the comparing unit; the comparing unit comprises a transducer and a PID (Piping and Instruments Diagram) temperature regulator; the transducer provides signals for the PID temperature regulator; the PID temperature regulator transmits the signals to the controller; the controller controls the operation of the coolant water; and the executing part comprises a frequency converter, a motor and a water pump and provides required temperature for the user side. The device tracks the parameter change by utilizing the frequency converter to regulate the energy flow, thereby achieving a good and stable control effect, also preventing electric energy waste caused by adopting baffles or door valves, saving energy, implementing convenience for control, and being suitable for the air conditioning devices of ocean ships.
Description
Technical field
The utility model relates to a kind of boats and ships convertible frequency air-conditioner device, belongs to the marine air conditioning field.
Background technology
In the cabin of large-scale ship, generally more airtight, circulation of air is slow, is easy to cause indoor temperature, appropriate inhomogeneous, and the people can feel unhappy discomfort, therefore need the system of installing an air-conditioner come temperature and appropriateness in the conditioning chamber.Ship air conditioning equipment generally all is that air is distributed to each cabin again through focusing on, and such aircondition is called centralized or central air conditioning plant.And the executing agency of the air-conditioning system of general boats and ships drives with alternating current generator; Usually adopt parts such as valve, baffle valve that parameters such as the pressure of system, flow are controlled; When variation of ambient temperature or hot and cold load variations, the time can be cold through increasing and decreasing, the quantity of warm water circulating pump or use the method for deep bead to regulate indoor temperature.This system not only regulating effect is not ideal enough, causes the fluctuation of indoor temperature easily, and a large amount of electric energy is consumed by parts such as baffle valve, valves.
The utility model content
The utility model relates to a kind of boats and ships convertible frequency air-conditioner device, and is undesirable in order to improve common air-conditioning system thermoregulation effect, the problem that energy consumption is big.
The method that the utility model adopted is: a kind of boats and ships convertible frequency air-conditioner device; Comprise operating part, controlled device, transducing part, comparing element and controller; Operating part comprises frequency converter, first water pump, second water pump and motor; Frequency converter connects first water pump, and motor connects first water pump and second water pump; Controlled device is a chilled water; Sensor comprises evaporimeter, and evaporimeter connects user side; Comparing element comprises transmitter and PID thermoregulator, and the water inlet pipe on the evaporimeter is connected with transmitter with return pipe, and transmitter is passed to the PID thermoregulator with signal, and the PID thermoregulator is connected with controller, and second water pump connects controller and motor.Water pump can replace with blower fan.The temperature difference of chilled water is 0-5 ℃ in said evaporimeter outlet pipe and the return pipe.
Its beneficial effect is: the actuator link that frequency converter and motor, water pump etc. are formed, its essence is adjustment energy stream, and tracking parameter changes, and plays the control effect, satisfies energy-conservation requirement; Avoid improving the precision of regulating, keep indoor temperature constant because the waste of energy that adopts baffle plate or valve to cause is realized the speed regulation of motor continuously smooth; Frequency converter adopts soft start, and the mechanical shock of minimizing equipment and motor and to the impact of electrical network reduces the fluctuation of electrical network parameter; The control system that frequency converter constitutes, tracking be and the closely-related characteristic parameter of system change process characteristics to disturb the influence that causes in order to overcome; The control system that frequency converter constitutes is applicable to foreign-going ship conservation measures and optimization.
