Problems solved by technology

Unfortunately, the control system only discloses a device structure for the control system of the central air-conditioning device, but does not provide the control method or control program of the central air-conditioning device, and it cannot be used for a large amount of supply at one time and control of large water source heat pump systems that consume hot water
The industry has not yet found a control method for a large water source heat pump system that can supply and consume a large amount of hot water at one time

Embodiment 1

[0035] B. Programming: The manager will input the sequence program of the hot water supply task, such as detecting the water level, detecting the temperature of the hot water in the pool, detecting the water supply pressure, etc., into the PLC programmable controller;

[0036] C. Inspection and diversion: PLC programmable controller scans to check whether the input program is faulty, if the input program is not faulty, then enter step D, if the input program is faulty, then enter step F;

[0037] D. Setting parameters: the management personnel set parameters such as water supply time 17:00-19:00, water supply temperature 55°C, and water level height of the heat preservation pool 1.81 meters (slightly more than required);

[0038] E. Enter the main program: the PLC programmable controller starts to execute the heating subroutine and the water supply subroutine through the signal transmission with the corresponding controller or / and sensor, and the corresponding heating subroutin...

Abstract

The control method of a large water source heat pump system belongs to a control method of a large water source heat pump system capable of supplying and consuming a large amount of hot water at one time. It transmits signals between the programmable controller and the corresponding monitoring equipment, executive equipment and sensors, after A-starting, B-programming, C-testing, shunting, D-setting parameters, E-including heating subroutines and water supply The main program of the subroutine and the F-stop program can timely, effectively, timely and accurately control the one-time large amount of hot water supply of the large-scale water source heat pump system. It can save a lot of unnecessary energy consumption, reduce the operating cost of equipment, reduce the failure rate, maintenance time and maintenance cost of the system and equipment, improve the utilization rate of system equipment, and flexibly adjust the water supply time and water supply volume of hot water. It can realize the automatic supply of hot water, greatly reduce the number of system operators and management personnel, minimize the operating cost of the system, and meet the requirements of emission reduction and environmental protection.

Description

technical field [0001] The invention relates to a control method of a water source heat pump system, in particular to a control method of a large water source heat pump system capable of supplying and consuming a large amount of hot water at one time. Background technique [0002] At present, most of the existing large-scale district heating systems adopt all-weather large-scale water-source heat pump heating systems integrated with multi-component heat pump systems. This heating system can supply and consume hot water in a limited amount without interruption around the clock. The control method adopted is to achieve the effect of uninterrupted and limited supply of hot water around the clock by detecting the water temperature and water volume in the storage tank, repeatedly starting or shutting down the heat pump unit, and intermittently heating and adding water. Because it supplies hot water continuously and in a limited amount, it cannot meet the needs of units such as ...
