Prediction-based control method and system for water intake of river water source heat pump in seawater topping area

Abstract

The invention relates to a predication based river water-source heat pump water intake control method and system for a seawater jacking area. The predication based river water-source heat pump water intake control method comprises the following steps: providing a river water-source heat pump water intake control system, and predicating time characteristic parameters of river water-source heat pumpoperation according to historical operation data of the river water-source heat pump water intake control system; obtaining river historical tide data, comparing and analyzing the river historical tide data with tide forecast data obtained by networking, and predicating specific time that seawater flows backwards and reaches a water intake position of a river water-source heat pump during flood tide every day; inputting the data into the system, utilizing a statistical regression analysis method for a machine learning method to intelligently train, and calculating the optimal dynamic water intake control method which corresponds to different time points after training. The river water-source heat pump water intake control system operates according to the dynamic water intake control method, can be ensured to stably extract fresh water from river flow in the seawater jacking action area throughout the year through dual control of large data predication and system real-time monitoring,and can realize long-term stable and reliable operation.

Description

technical field [0001] The invention relates to the technical field of water source heat pumps, in particular to a prediction-based method and system for controlling water intake of river water source heat pumps in seawater jacking areas. Background technique [0002] In the field of water source heat pump, the surface water heat pump system has been highly praised by users for its low cost and relatively simple construction. However, in the actual project implementation process in coastal areas close to river estuaries, due to the constraints of water inflow conditions, the water intake point on the water source side of the water source heat pump unit needs to meet: 1. The water intake point should be located in the constant temperature layer of the water body; 2. Water intake Points must also meet the requirements of water intake conditions and temperature in dry seasons and flood seasons, and water must be able to be taken when the water level is lowest in dry seasons.

Problems solved by technology

[0003] In the above cases, if the conventional water intake device in the river water source heat pump without seawater corrosion resistance is used, because the seawater is poured into the river channel from the river estuary when the sea water level rises, the river water drawn by the water intake device from the water intake point may be mixed. Seawater, causing seawater to enter the river water source heat pump unit, will easily cause corrosion of the water intake piping system in the river water source heat pump unit and the condenser of the heat pump unit, and affect the stability and safety of the water intake piping system and heat pump unit
