Abstract

The invention relates to a valve control method, in particular to a remote valve control method which is used in a central air conditioner system for storing energy and combining terrestrial heat. A central air-conditioner has the functions of multi-mode automatic switching control, dynamic flow balance control and room constant temperature control through adopting a programmable controller with high mathematical function calculating function, an electric executer and a plurality of valves and acquiring information of parameters of controlled objects of all places in the air conditioner system. The method can be applied to the central air conditioner system with an energy storage water tank and is especially suitable for the central air conditioner system for storing the energy and combining the terrestrial heat. The valves are independently controlled dynamically by using the programmable controller so as to directly realize the automatic balance of the dynamic flow and further realize the room constant temperature control of the central air conditioner. When the valve control method is adopted, the air temperature fluctuation value of a user end is 40-90 percent less than that calculated in the traditional valve control method, and the comprehensive energy consumption of the central air conditioner system is saved 8-33 percent than that adopted in the traditional valve control scheme.

Description

technical field [0001] The invention relates to a valve control method, in particular to a remote valve control method. Background technique [0002] In recent years, a large number of air-conditioning projects have adopted water tank energy storage technology, and even some central air-conditioning systems have adopted a combination of geothermal and energy storage. Exchange heat between heat pump equipment and shallow underground resources such as soil, groundwater, and surface water, use low-valley electricity to make ice at night in summer, and supply cooling during the day; use low-valley electricity and geothermal heat storage at night in winter, and heat during the day and heat And provide heat source. This system makes full use of high-grade and low-grade energy, maximizes the advantages of the two grades of energy, and greatly optimizes the energy structure. Two different air-conditioning systems make full use of their respective advantages. The ground source heat...
