Problems solved by technology

Although the first method in the above four methods has the effect of comprehensive utilization of natural energy (plant stalks), the combustion value is low, and the long heating time is its shortcoming
The second method has the advantage of instant use, that is, hot water can be obtained once it is ignited, but its safety and economy are relatively poor.
Compared with the gas water heater of the second method, the safety of the third method (electric heating water heater) has been significantly improved, but if the water is to be heated to a temperature suitable for use, such as about 50-60 ° C, it is necessary to wait for a reasonable time. For example, using a 1 kilowatt electric heating water heater, it takes more than 3-4 hours to heat water (80 liters) at a normal temperature of 15°C to a bathing temperature of 50-60°C. If the power of the heating element is increas

Embodiment 1

[0019] Please refer to the accompanying drawings, the solar heat collecting device 1 shown in the figure includes a water tank 1, a group of vacuum heat collecting tubes 12 and supports 13 whose number is not limited by the number shown in the figure, and the lower ends of each vacuum heat collecting tubes 12 are supported on the vacuum tubes of the support 13 On the seat 131, and the upper end of each vacuum heat collecting tube 12, that is, the open end of the vacuum heat collecting tube 12 is matched with the water tank 11 and communicated with the water tank cavity 111. One end of water tank 11 promptly is connected with a water inlet 112 and a water return interface 113 by the left end of the position state shown in the present accompanying drawing, and the water inlet and return interfaces 112, 113 all communicate with the water tank chamber 111. In order to make the water tank 11 have a good thermal insulation effect, a water tank insulation layer 114 is provided outside...

Embodiment 2

[0025] Only the inner diameter of the heat exchange tube 3 is changed to 12mm and the total length is changed to 40m, and the rest are the same as the description of embodiment 1.

[0026] According to the applicant's test, it only takes 30 minutes to heat 100 L of water in the water tank chamber 111 from a normal temperature of 15° C. to 50-60° C. using a heat pump device 2 with a power of 1.5 horsepower, that is, 1.1025 kilowatts. By adopting the technical solution provided by the present invention, there is no need to worry about the influence of the solar heat collector 1 on climate and seasons, and there is no need to worry about the cleanliness of the water from the heat exchange tube 3. In addition, since the heat exchange tube 3 is connected to the tap water pipeline, Therefore, it has an ideal spray effect.

Abstract

The invention relates to a pressure-bearing type solar heat pump water heater, belonging to the technical field of solar water heaters. The pressure-bearing type solar heat pump water heater comprises a solar heat collection device and a heat pump device, wherein the solar heat collection device consists of a water tank, a set of vacuum heat collection pipes and a bracket, and the heat pump device consists of a compressor, an evaporator and a condenser. The water tank and the vacuum heat collection pipes are together arranged on the bracket, the cavity of each vacuum heat collection pipe is communicated with the cavity of the water tank, a water inlet and return joint is arranged on the water tank in an extending mode, and the water inlet and return joint is communicated with the cavity of the water tank. The pressure-bearing type solar heat pump water heater is characterized in that the cavity of the water tank is provided with a heat exchange pipe; the condenser comprises condensing sleeve in a spiral bending shape and a refrigerating medium pipe, wherein one end of the condensing sleeve is connected with a heat pump water outlet pipe, and the pipeline of the heat pump water outlet pipe is provided with a circulating pump. In the technical scheme, water in the cavity of the water tank is heated by the cooperative action of the heat pump device and the solar heat collection device so that the supply of hot water is ensured. The invention has remarkable effect of saving electric energy, can improve the spraying bath effect and does not cause the situation that water is polluted by bacteria.

Description

technical field [0001] The invention belongs to the technical field of solar water heaters, in particular to a pressure-bearing solar heat pump water heater. Background technique [0002] There are mainly four heating methods for people to heat water for daily life: one is the traditional way of heating water with plant straw and farm stoves, which is more common in rural areas; the other is to use gas water heaters; the third is to use electric heating water heaters (referred to as electric water heater); the fourth is to use solar water heaters. Although the first method in the above four methods has the effect of comprehensive utilization of natural energy (plant stalks), its combustion value is low, and the long heating time is its shortcoming. The second method has the advantage of immediate use, that is, once it is ignited, hot water can be obtained, but its safety and economy are relatively poor. Compared with the gas water heater of the second method, the safety of...
