Abstract

The invention discloses an air energy heat pump heat supply and heating system with a water tank inside. The air energy heat pump heating system comprises a machine unit part, a heat supply part, a heating part and an intelligent control part. The machine unit part comprises an air energy heat pump heating part, an electric heating part, a water way pipeline part and a control circuit part, the control circuit part is used for starting a compressor for heat supply when the temperature of the small-volume water tank is smaller than the starting temperature difference of the compressor, and when the temperature of the small-volume water tank reaches the set temperature, the electric heating part is controlled not to output electric heating power; when the temperature of the small-volume water tank can not reach the set temperature, according to the detected temperature difference of going-in water and going-out water and flow detected by the water way pipeline part, the electric heating part is controlled to output needed electric heating power; when the air energy heat pump heating part and the electric heating part both output power in a full-power mode and the temperature of the small-volume water tank does not reach the set temperature, according to the detected temperature, the water way pipeline part is controlled to regulate water flow through a water flow regulating valve to enable water temperature to be constant.

Problems solved by technology

[0002] The traditional built-in water tank air energy heat pump heating system generally consists of three parts, one is the host part, the other is the water tank part, and the third is the heating system part; for household water tanks, 1. The capacity is generally 150-320L, and the water tank The volume is huge, and it needs to occupy a large part of the building area during installation. Even if some water tanks are installed outside the wall with brackets, due to the weight of the water tank itself, this kind of installation method is quite dangerous; Material and process, no matter it is stainless steel liner or enamel liner, due to the defects of manufacturing process, water tank leakage is unavoidable; 3. The heat exchanger inside the water tank generally uses copper or stainless steel tubes. In areas with poor water quality, replace The heat pipe will be corroded and perforated, resulting in refrigerant leakage. Once a leakage occurs, it will be fatal to the unit; 4. The main unit and the water tank need to be connected by a connecting pipe, so it is difficult to avoid artificial refrigerant leakage during installation ;5. Due to the characteristics of the water storage heat pump, the water temperature needs to be raised to a higher temperature, and it takes a long time, which cannot meet the immediate water requirements, and in the later stage of water use, the water temperature fluctuates greatly, which affects the comfort of use; In addition, the condensing temperature determines the energy consumption of the unit. The traditional unit with a water tank operates at a high condensing temperature and high condensing pressure for a long time, which will be a great test for the life of the compressor; 6. Use a water storage tank , when using water, it is generally necessary to mix the water, which will cause several problems, 1) the hot water usage rate in the water tank is not high; 2) the water temperature will inevitably drop during the heat preservation process of the water tank, which will increase energy consumption; 3) the user When installing a water valve at home, it is necessary to install a water mixing valve, which increases the cost of materials

7. When the general heating system uses the heat in the water tank, it is necessary to install a heat exchange coil inside the water tank to form a closed circuit with the floor heating coil or the radiator and the circulating water pump, which increases the difficulty of the production process of the water tank and occupies Water tank volume; 8. The traditional heating system does not have intelligent control, and it cannot perform various remote monitoring on the heating system, which cannot meet the more humanized needs of modern people: 1) For example, users need to start heating in advance or at regular intervals, But when there is no one at home, it cannot be realized; 2) The user forgets to turn off the heating or heating water when he is outside for a long time, and the heating or heating water cannot be turned off remotely; 3) Some failures occur in the traditional heating and heating system , requires on-site analysis and exclusion, especially in weak or remote areas after-sales outlets, the timeliness of after-sales service and user satisfaction are greatly reduced
