Problems solved by technology

However, assuming that there are 50 double-employee households going to work during the day, if the existing design is used, it needs to be operated at full capacity. If the residents close the valves by themselves, the pressure on the heating pipes will be a test and there will be certain risks.

Abstract

The invention discloses an automatic control system for a tap water source heat pump, which belongs to the technical field of tap water heat pumps, and can change the output power of a motor along with the change of loads at tail end, lower energy consumption, and guarantee the long-term and safe operation of the overall system at the same time. The system adopts the technical scheme that the control of the overall system is realized by mainly uniformly controlling temperature, pressure, flow and differential pressure of the tap water source heat pump. The automatic control system comprises a tail-end flow control loop, a differential pressure control loop, a tail-end backwater temperature control loop, a secondary hydrological cycle flow control loop, a tap water temperature difference control loop and a tap water negative pressure prevention control loop, and is mainly applied to heating of building users.

Description

technical field [0001] The invention relates to an automatic control system for a tap water source heat pump, belonging to the technical field of tap water heat pumps. Background technique [0002] The tap water source heat pump system operates according to the principle of heat balance and material balance. It consists of four closed loops. The first one is the tap water circulation loop, which is also a heat source loop. Usually the tap water temperature is 8-23 degrees. It is designed to use The temperature difference is 7 degrees. The tap water passes through the stainless steel plate heat exchanger and transfers the heat to the secondary water circulation loop. The circulating water absorbs the heat and enters the water source heat pump host. The function is to transfer the heat to the end load circuit through the cycle process of evaporation and condensation of the working fluid. The outlet water temperature of the condenser can reach 45 degrees, and the return water t...
