Description

Technical Field

[0001] The utility model belongs to the technical field of leakage protection, in particular to a leakage resistor interrupter and an air-conditioning water heater system using the same. Background Art

[0002] With the development of society, people's living standards are constantly improving. People's requirements for living environment are not limited to the expansion of living area, but more and more people are beginning to pursue the comfort of living environment. Therefore, most residential buildings are equipped with air conditioning systems, which provide people with a comfortable indoor living environment for heating in winter and cooling in summer. Similarly, as people's quality of life improves, the demand for domestic hot water is also increasing.

[0003] The usual practice was to set up an air conditioning system and a water heater system separately in the living space. The air conditioning system is used for cooling and heating, and the water heater system is used to produce domestic hot water. However, the air conditioning system currently used consumes a lot of electricity, and a large amount of condensation heat discharged by the system air conditioning in summer directly enters the outdoor environment, which not only causes energy waste, but also pollutes the environment, exacerbating the urban heat island effect. At present, the water heaters used to produce domestic hot water mainly include fuel gas water heaters, electric heating water heaters, solar water heaters, etc. Fuel gas water heaters are a kind of water heater that heats water by burning liquefied gas, natural gas, kerosene, alcohol lamp minerals or organic dyes. This type of water heater is easily affected by factors such as the degree of fuel combustion and water pressure fluctuations, resulting in large fluctuations in water temperature. In the case of insufficient oxygen supply, it is easy to produce toxic gases such as carbon monoxide, which is very harmful to the human body. In serious cases, it may cause poisoning incidents. More importantly, it consumes a large amount of non-renewable resources, has a high cost of use, and has a large impact on the environment. An electric water heater is a water heater that heats water by consuming high-grade electricity. This type of water heater is convenient to use, but the efficiency of using electricity is relatively low, and there is a safety hazard of electric shock. A solar water heater is a water heater that uses a vacuum tube to collect solar energy to heat water. This type of water heater is environmentally friendly and has low operating costs, but it is greatly affected by weather conditions. It is difficult to use normally on cloudy days, rainy days, and other days with low sunshine intensity. Therefore, general solar water heaters have auxiliary electric heating devices, so solar water heaters have the same defects as electric water heaters.

[0004] From the above, it can be seen that although these practices of separately setting up air conditioning and water heater systems in living spaces can meet different usage requirements, this practice requires two systems, which increases costs, while causing energy waste and greater pollution. In addition, the system is complex and inconvenient to control.

[0005] As shown in the Chinese invention patent application with publication number CN 101776350 A, it discloses an integrated air conditioner and water heater. Most of the existing integrated air conditioners and water heaters are as shown in the above structure. They can combine air conditioners and water heaters to meet different usage requirements, improve energy utilization, reduce pollution, and solve the above technical problems very well. However, there are defects as follows: the compressor, heat exchanger, indoor unit and outdoor unit are all made of metal. The existing equipment does not perform electrical isolation at the metal connecting pipe between the heat exchanger and other devices. Once the compressor is damaged or other parts leak electricity, the water in contact with the metal heat exchanger will be charged, which can easily cause electric shock to people and equipment in contact with the water, posing a safety hazard.

The first leakage circuit breaker and the second leakage circuit breaker both adopt the above-mentioned leakage circuit breaker device.

[0015] Therefore, the air-conditioning water heater system of the utility model adopts the above-mentioned leakage resistor interrupter, which has low leakage risk and high safety.
