Abstract
It is energy conservation automatic control system of water source heat pump well water flow. It is made up of water inlet temperature sensor, return water temperature sensor, machine group controller, frequency converter and well water pump electric machine. Its feature is, in the well water admitting pipe and the return pipe of the water source heat pump assembly, there are their each influent water temperature sensor and return water temperature sensor. The influent water temperature sensor and return water temperature sensor connects each machine set controller, then the machine set controller connects with transducer, finally the transducer connects with well water pump electric machine. The device can control the well water flow automatically according to the actual load quantity. Whatever the controller increases or decreases the output of the water flow, it can keep the system load automatic balance and make it in the stable condition.
Description
Technical field
The present invention relates in a kind of air-conditioning refrigeration system automaton to water source heat pump units well water flow.
Background technology
A kind of water source heat pump units equipment that is called can utilize underground well water to obtain the high energy efficiency ratio as Cooling and Heat Source with it in the operation of air conditioning systems, firmly gets user's welcome.In water source heat pump units when work, be converted to high-grade thermal source with low-grade thermal source in the underground water by source pump and supply with the user and use, and resulting heat of user or cold are actually and are taken from the underground water, thereby have that expense is low, the efficient advantages of higher.In other words, underground water is in certain temperature range, and the mechanical equivalent of heat of user side gained or cold and phreatic flow are roughly proportional.But common water source heat pump units is in operation, and the well water pump of unit is with fixing flow, i.e. after the unit start, no matter the user side actual load is big or little, and well water pump is all worked in the mode of flowing full amount.Therefore, under the little situation of user side load, still running at full speed of water pump, the situation during by full load provide the well water flow, have caused the pump motor waste of electric energy, also are a kind of waste of resource simultaneously to underground water.
Summary of the invention
The object of the present invention is to provide the energy-conservation self-con-tained unit of a kind of water resource heat pump well water flow.The size of actual load was automatically controlled the extraction amount of well water when this device can be worked according to water source heat pump units, to reach the purpose of saves energy and water resource.
The present invention is achieved like this, it comprises inflow temperature sensor, generator set controller, return water temperature sensor, frequency converter, well water pump motor, well water in water source heat pump units advances, be connected with inflow temperature sensing and return water temperature sensor respectively on the water return pipeline, advance, return water temperature sensing pipe junctor group controller respectively, generator set controller connects frequency converter, and frequency converter connects the well water pump motor.
The present invention can be according to the size of actual load control well discharge automatically, and no matter controller strengthens or reduce the output of flow, all can with the system loading self-poise to a kind of stable status.
Description of drawings
Fig. 1 is a fundamental diagram of the present invention.
In the drawings: 1, water source heat pump units 2, inflow temperature sensor 3, return water temperature sensor 4, generator set controller 5, frequency converter 6, well water pump motor 7, water inlet pipe 8, return pipe
Embodiment
As shown in Figure 1, the present invention is connected with inflow temperature sensor (2) and return water temperature sensor (3), two temperatures sensor junctor group controller (4) respectively respectively on the well water water inlet pipe (7) of water source heat pump units (1) and return pipe (8), generator set controller connects frequency converter (5), and frequency converter connects well water pump motor (6).In generator set controller, preestablished the program of advancing return water temperature difference and processing, generator set controller calculates the temperature difference according to actually advancing of being collected, return water temperature, and compare with the water temperature difference of setting, when the actual temperature difference when setting the temperature difference, illustrate that this moment user's actual load is bigger than normal, need increasing well water flow, controller strengthens the output of curtage, the frequency converter output frequency is increased, and the well water pump rotating speed of motor rises, and the flow of well water strengthens.Otherwise, when the actual temperature difference when setting the temperature difference, illustrate that this moment user's actual load is less than normal, need reduce the well water flow, controller reduces the output of curtage, and the frequency converter output frequency is reduced, the reduction of well water pump rotating speed of motor, the flow of well water reduces.Above process is in certain scope, and water source heat pump units can be according to the size of actual load control well discharge automatically.No matter controller strengthens or reduces the output of flow, all can with the system loading self-poise to a kind of stable status.
Claims (1)
1, the energy-conservation self-con-tained unit of a kind of water resource heat pump well water flow, it comprises inflow temperature sensor, return water temperature sensor, generator set controller, frequency converter, well water pump motor, it is characterized in that on the well water water inlet pipe of water source heat pump units and return pipe, being connected with inflow temperature sensor and return water temperature sensor respectively, inflow temperature sensor and return water temperature sensor be the junctor group controller respectively, generator set controller connects frequency converter, and frequency converter connects the well water pump motor.
