Description

Special water tank for solar air conditioner

technical field

The utility model relates to a solar water tank.

Background technique

Existing solar water tanks can heat the water in the tank when there is sunlight; when there is no sunlight, such as night, cloudy, rainy, snowy or cold weather not exceeding minus 20°C, in order to solve the heating problem , people adopt the mode of electric heating to realize the heating of water in the water tank.

Contents of the invention

The purpose of the utility model is to provide a special water tank for solar air conditioning which combines solar heat collection with heat pump unit heat collection.

The structural design scheme to achieve the above purpose is as follows:

The special water tank for solar air conditioners includes a tank body, water inlet pipe, and water outlet pipe. The tank body is located in the outer cylinder, and the insulation layer is between the tank body and the outer cylinder. The inner tank is composed of a closed double-layer jacket, and the wall of the closed double-layer jacket is equipped with a low-temperature liquid working medium; the outer side of the inner tank is surrounded by a heat pump circulation pipe, and the inlet and outlet of the heat pump circulation pipe The outlet of the pipe extends to the outside of the outer cylinder; the inner tank of the interlayer of the box is provided with an overflow nozzle, a solar cycle refrigerant inlet and a solar cycle refrigerant outlet, and the overflow nozzle, the solar cycle refrigerant inlet and the solar cycle refrigerant The outlets all extend to the outside of the outer cylinder.

The inner wall of the box liner is provided with a polymer plastic spraying layer.

The beneficial technical effect of the utility model is:

1. This utility model realizes the structural design of combining solar heat collection and heat pump unit heat collection. Under the condition of better sunlight, the heat energy collected by solar energy and heat pump unit can be quickly stored in the double-insulation polymer plastic coating. In the water tank of the inner tank, the temperature of the ambient water of the heat pump unit is increased. When the solar energy cannot collect enough sunlight, the heat pump hot water unit with low temperature resistance will supplement the heat supply in time; ensure that the water tank can provide all-weather temperatures above 55°C at any time. sanitary hot water.

2. The water tank adopts a double-layer jacketed tank wall structure and a heat pump unit circulation coil structure. The two-way heat collection and heat exchange of the liquid anti-low temperature working medium in the double-layer jacket is used to heat the water in the tank. Its design is ingenious , the structure is reasonable, which not only reduces the maintenance rate of the system, because it uses solar energy to increase the temperature of the heat pump's ambient water and reduces the annual start-up rate of the heat pump unit, thus prolonging the service life of the heat pump unit, and at the same time, it also saves the user's water tank. The floor space is reduced, the manufacturing cost is reduced, and the utility model is more energy-saving.

3. In order to ensure sufficient heat supply when the geothermal heating is started, the utility model adopts a 40L small-capacity water tank for the geothermal heating, which is set separately from the sanitary hot water insulation water tank. At the same time, the principle of the utility model is used for heat exchange to avoid Floor heating circulating water is strung into sanitary hot water to cause pollution.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Example 1:

The special water tank for solar air conditioners includes a box body, an inner tank cover 10, a water inlet pipe 5, a water outlet pipe 3, an outer cylinder 13, and an upper cover 11. The box body is located in the outer cylinder 13, and the polyurethane hair Bubble insulation layer 14.

The box wall of the box body is a closed double-layer jacket shape composed of an inner tank 6 and a sandwich inner tank 7, and the inner tank 6 and the sandwich inner tank 7 are sealed and connected by a flange, and the closed double-layer jacket shape The wall of the tank is provided with anti-low temperature liquid working medium 17; it is used for the heat exchange of the solar heat collector and the heat exchange of the heat pump working medium circulation pipe. A heat pump circulation pipe 1 is arranged around the outside of the tank inner liner 6. The inlet and outlet ports 12 of the heat pump circulation pipe 1 extend to the outside of the outer cylinder 13. The inside of the heat pump circulation pipe 1 is a cold medium resistant to low temperature compressors. The box interlayer liner 7 is provided with an overflow nozzle 4, a solar circulating working fluid inlet 8 and a solar circulating working fluid outlet 9, and the overflow nozzle 4, the solar circulating working fluid inlet 8 and the solar circulating working fluid outlet 9 are all Stretch to outer cylinder 13 outsides.

The inner wall of the box inner liner 6 is spray-coated with a polymer plastic layer 16, which reduces scaling on the inner wall of the box.

A temperature-sensing probe insertion rod 15 is arranged in the inner liner 6 of the box.

During installation and use, the inlet and outlet ports of the heat pump circulation pipe 1 are respectively connected to the circulation refrigerant pipes of the heat pump compressor, and the solar circulation working medium inlet 8 and the solar circulation working medium outlet 9 are respectively connected to the solar heat collector.

The working principle of the special water tank for solar air conditioning is as follows:

The first cycle is the solar heat collection cycle. When the sunlight condition is good, the solar heat collector will collect the heat energy through the solar cycle working medium to perform a one-way cycle through the cycle interfaces 8 and 9, and improve the internal temperature of the double-layer jacket of the water tank. The temperature of the anti-low temperature working medium can realize the heating of the water in the inner tank of the water tank;

When there is no sunlight and cold weather, the heat pump unit replenishes the water in the inner tank of the heating water tank at any time through the communication cycle of the heat pump circulation pipe 1 and the circulating refrigerant of the heat pump compressor.
