The invention discloses a solution pump control method of a heat source tower system. The concentrated solution pump working mode is divided into a constant concentration mode and a freezing point mode; the constant concentration mode: when the concentration of the heat source tower system does not reach the set concentration range, the concentrated solution circulation pump starts Supplement concentrated solution to the heat source tower, and the density meter detects that the system concentration reaches the set concentration range to stop replenishment; freezing point mode: adjust the system concentration according to the set freezing point hysteresis, the adjustment point is less than the set value, turn off the heat source tower fan, and fill the system Set the concentration and temperature of the solution, the density meter detects that the system density reaches the set concentration, and the centrifuge is turned off after a period of time delay. The solution pump control method of the heat source tower system provided by the present invention, the working mode of the concentrated solution pump is divided into a constant concentration mode and a freezing point mode, especially a freezing point mode, which can adjust the system concentration according to the set freezing point hysteresis, and the liquid replenishment is timely and reliable , so as to improve the working efficiency of the heat source tower system.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to a control method for a heat source tower system solution pump. Background technique [0002] In recent years, a new type of heat pump system has come into people's eyes, that is, the heat source tower heat pump system. The low-grade heat energy in the air is extracted through the heat source tower to supply end users. Compared with ground source heat pumps and air source heat pumps, heat source tower heat pumps can not only overcome the shortcomings of the ground source heat pump system due to geographical limitations, but also avoid the frosting problem of the air source heat pump system in winter conditions. However, due to the heat source tower heat pump application in the northern region is not mature. [0003] The energy tower uses the contact between water and air to absorb or release heat energy from the air. The carrier medium with a freezing point below zero is used...
