Embodiment 1

[0039] When heating water:

[0040] Fill water into the water heater tank through the cold water inlet until the water level in the water heater tank reaches the highest level, close the cold water inlet, set the temperature threshold through the control device, and heat through the heat exchange pump in the water heater;

[0041] During the heating process, the hot water is transferred to the water storage tank through the circulation pump;

[0042] The number of cycles and temperature measurement time are set by the control device. The circulating pump receives the signal from the control device. Within a certain period of time, the circulating pump circulates a fixed number of times, and at regular intervals, the temperature in the data acquisition device is tested. The meter performs multiple temperature measurements on the water temperature in the water storage tank, and calculates the average value of a single measurement; and compares the average value with the temperat...

Embodiment 2

[0045] When using heat:

[0046] During the use of hot water, the water heater tank is filled with water through the cold water inlet, and at the same time, it is circulated and heated by the heat exchange pump, and the cold water inlet and the water outlet of the water storage tank are simultaneously injected into the water heater tank and circulated; Then close the cold water inlet;

[0047] The water temperature in the water tank is circulated and heated by the heat exchange pump in the water heater tank, and at the same time, the hot water is pumped into the water storage tank by the circulation pump;

[0048] The temperature measurement time is set by the control device, and at regular intervals, the temperature tester in the data acquisition device performs multiple temperature measurements on the water temperature in the water storage tank, and calculates the average value of a single measurement; and compares the average value with Compare the temperature threshold; ...

Embodiment 3

[0051] When using warm water:

[0052] During the use of hot water, if the temperature threshold is set low and the average value of the water temperature is high, the cold water inlet will be opened, and the water heater tank will be filled with water through the cold water inlet, and at the same time, the heat exchange pump will circulate to balance the water temperature, and the circulation pump will The hot water is pumped into the water storage tank, and the temperature measurement time is set through the control device. At regular intervals, the temperature tester in the data acquisition device measures the temperature of the water in the water storage tank multiple times, and calculates the single measurement the average value; and compare the average value with the temperature threshold;

[0053] If the average value is higher than the temperature threshold, the cold water inlet and the water outlet of the water storage tank will inject water into the water heater tank...

Abstract

The invention provides a solar water heater efficiency testing device. The solar water heater efficiency testing device comprises a water heater water tank and a circulating device connected with thewater heater water tank, the circulating device comprises a circulating pump connected to a water outlet of the water heater water tank, a water storage tank connected with the circulating pump and adata acquisition device connected to the water storage tank, multiple temperature testers can be tested together, and errors are reduced. The circulating pump is used for guiding out hot water in thetank to measure the temperature consistency in the tank, the temperature accuracy is improved, layering of the water temperature in the tank is avoided, the hot water is prevented from being only located at the top of the tank and the joint with an heat exchanger, and water temperature balance is facilitated; data acquisition equipment is convenient to place, and the position of the acquisition device can be changed by changing the connecting pipe length; the length of the wires of the thermometers can be very short, and thereby errors caused by electronic information propagation are reduced.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a testing device and method for the efficiency of a solar water heater. Background technique [0002] Balcony wall-mounted indirect solar energy equipment mainly consists of photovoltaic heat collecting plate (vacuum heat collecting tube) heat collecting device, water storage tank, thermal energy conversion device, heat transfer medium, etc. This type of solar energy device is the most common household model, and its operating principle The collector converts solar energy into thermal energy of the heat transfer medium. Part of the heat transfer medium exists in the heat collector, and part of it exists in the heat conversion device in the water storage tank. The energy is transferred through the circulation pump or the energy potential of the cold and heat medium. , and finally the heat energy of the heat transfer medium is transferred to the water in the water storage ta...
