Marine variable chilled water volume air conditioning system

Abstract

The invention relates to a marine variable chilled water volume air conditioning system. The marine variable chilled water volume air conditioning system comprises a water chilling unit and an air conditioning device; the water chilling unit is connected with a chilled water inlet pipe of the air conditioning device through a variable frequency pump and a flowmeter, a pressure difference sensor is arranged between an inlet and an outlet of the variable frequency pump, and the chilled water inlet pipe and / or a chilled water outlet pipe are / is provided with electric adjusting valves / an electric adjusting valve. Water flow is adjusted in real time through the variable frequency pump to meet the actual load requirement of the air conditioning system. The purposes of saving energy and reducing noise are achieved by reducing rotating speed of a pump motor.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a marine variable water volume air conditioning system. Background technique [0002] With the development of global ocean-going ships and the comfort of the crew to the living environment, more and more air-conditioning systems use indirect water cooling. It is mainly composed of chiller, circulating water pump and air conditioner. For the air-conditioning water system of ordinary ships, no matter how the heat load of the hull changes, a fixed water flow rate is adopted. However, due to the influence of solar radiation and other factors, there will inevitably be differences in heat load between the inner zone and the outer zone, and the actual water flow required by the air-conditioning device is also different. If a fixed water flow rate is used for water supply, it will inevitably cause waste of energy, and even some cabins will be overcooled in summer and overheated in winter, ...

Problems solved by technology

However, due to the influence of solar radiation and other factors, there will inevitably be differences in heat load between the inner zone and the outer zone, and the actual water flow required by the air conditioner is also different.

If a fixed water flow is used for water supply, it will inevitably lead to waste of energy, and even individual cabins may be overcooled in summer and overheated in winter, seriously affecting the comfort of the crew.
