Water source heat pump intelligent centralized control all-in-one machine capable of spontaneously changing flow

Abstract

The invention provides a water source heat pump intelligent centralized control all-in-one machine capable of spontaneously changing flow, which aims at saving the energy and being convenient to install, use and maintain. The all-in-one machine comprises a water source pipeline with a water-source-side water return port and a water-source-side water supply port, a user pipeline with a user-side water return port and a user-side water supply port and a heat pump unit which is used for the user pipeline and the water source pipeline to exchange the heat, both the user pipeline and the water source pipeline are respectively provided with a water pump, a flow meter and a temperature sensor, a pressure difference transmitter is arranged between the user-side water return port and the user-side water supply port of the user pipeline, a bypass branch is arranged between the user-side water return port and the user-side water supply port, and the bypass branch is provided with a continuous electric two-way valve; and the heat pump unit, the water pump, the flow meter, the temperature sensor, the pressure difference transmitter and the continuous electric two-way valve are connected with a controller. Due to adopting the water source heat pump intelligent centralized control all-in-one machine, the variable-flow control can be realized, the high-efficient and energy-saving running of the unit can be guaranteed, and simultaneously compactness and reliability in structure and convenience in installation, use and maintenance can be achieved.

Description

technical field [0001] The invention belongs to the technical field of central air-conditioning manufacturing, and in particular relates to an intelligent centralized control all-in-one machine for water source heat pumps with self-variable flow. Background technique [0002] The energy crisis and global warming are common problems faced by the whole world. Measures to solve the above problems, such as using more efficient equipment, using renewable energy, and reducing carbon emissions, have become the research objects of various countries. At present, the demand for air-conditioning is growing rapidly, and the energy consumption of air-conditioning is also increasing rapidly. The energy consumption of air-conditioning systems accounts for a considerable proportion of the energy consumption of the entire building. Therefore, it is particularly important to improve the efficiency and optimize the performance of air-conditioning systems. [0003] The central air-conditioning ...

AI Technical Summary

Problems solved by technology

When the user wants to realize the centralized control management and remote monitoring of the entire central air-conditioning system, another control system needs to be configured, and the integrity and compatibility of operation and maintenance are relatively poor.
