Example one
As shown in fig. 1, a commercial large-scale pressure-bearing air can hot water system, including heat pump 2 and heating circulation pump 3, heating water tank 4, heat storage water tank 5, heat-retaining circulation pump 6. The heating water tank 4 is connected with the heat pump 2, and the heating circulating pump 3 is respectively connected with the heating water tank 4 and the heat pump 2; the number of the heat storage water tanks 5 is not less than one, and the heat storage water tanks 5 are connected with the heating water tank 4; the heat storage circulating pump 6 is respectively connected with the heating water tank 4 and the heat storage water tank 5 and is used for pumping hot water in the heating water tank 4 into the heat storage water tank 5. The heating water tank 4 and the heat storage water tank 5 are both closed pressure-bearing water tanks.
The cold water is directly supplemented into the heating water tank when being supplemented, the cold water is heated in the heating water tank, so that the cold water cannot cause the fluctuation of the temperature of hot water in the heat storage water tank, the heating water tank is heated according to the temperature, and the hot water is heated after the temperature in the heating water tank is lower than the set temperature. And when the hot water in the hot water storage tank is lower than the set water level, the hot water in the heating tank is supplemented into the hot water storage tank through the heat storage circulating pump.
Cold and hot water is stored in separate bins, cold and hot water mixing cannot occur between the water tanks, the problem of water supply temperature fluctuation caused by cold and hot water mixing due to a large amount of water replenishing in a peak period is avoided to the greatest extent, and all-weather constant-temperature constant-pressure hot water is really provided.
And temperature sensors are arranged in the heat storage water tank and the heating water tank and used for controlling the water temperature.
When the heat storage water tanks are provided with a plurality of water tanks, the heat storage water tanks are connected in series, or the heat storage water tanks are divided into a plurality of water tank groups, the heat storage water tanks in each water tank group are connected in series, and the water tank groups are connected in parallel.
The heat storage water tanks with small volume occupy small area, low height and light bearing weight, can be compactly and seamlessly arranged and combined, are suitable for compact installation, can be randomly combined indoors and outdoors, and can adapt to various installation spaces.
When the temperature of water in the heating water tank reaches a set temperature, each heat storage water tank is filled with hot water through internal water flow circulation. When hot water is used, the hot water in the storage water tank is used, the outlet water temperature of the hot water is relatively stable, cold water enters the heating water tank, the heat pump heats the cold water, the working strength of the heating system is much lower, and the energy-saving effect is achieved.
Because the heating water tank and the heat storage water tank are adopted, the volume of the heating water tank is greatly reduced, the heated water is less, the power of the compressor can be reduced, and long-time high-power work is not needed.
The hot water in the heat storage water tank is directly used, and no cold water enters the heat storage water tank, so that the temperature of the water in the heat storage water tank is constant, and the water outlet temperature of the faucet can not fluctuate as long as the water outlet quantity of the cold and hot water faucet is adjusted once during use, so that the water outlet temperature is constant.
As shown in fig. 1, the heat pump 2 is communicated with the heating water tank 4 through a first water pipe 11 and a second water pipe 12, wherein the second water pipe 12 is provided with a heating circulation pump 3.
