Abstract

The invention discloses an improved air energy water heater. The improved air energy water heater mainly consists of a compressor, an evaporator, a heat-exchange water tank, a throttling device, a defrosting system and a main controller, wherein the evaporator comprises a plurality of copper pipelines, an inlet pipeline, an outlet pipeline and a plurality of fins, the copper pipelines are arranged in parallel, and the fins are in wave shapes; the heat-exchange water tank comprises a heat exchanger, a liner and a flange plate, the heat exchanger is fixedly connected with the flange plate, the flange plate is fixedly and detachably connected with the liner, the heat exchanger comprises an inner coiled pipe and an outer coiled pipe, the inner coil pipe is arranged in the liner, and the outer coiled pipe is coiled on the side face of the outer circumference of the liner; the throttling device is provided with an electronic expansion valve, and the electronic expansion valve is electrically connected with the main controller; the defrosting system is provided with a humidity sensor. The improved air energy water heater disclosed by the invention has the advantages of reliable, safe and high-efficiency operation at all seasons, convenience in installation, simple maintenance and the like.

Description

Technical field: [0001] The invention relates to an air energy water heater, in particular to an improved air energy water heater, which is suitable for fully utilizing the energy of air to heat water. Background technique [0002] At present, there are many problems in the air-energy water heaters on the market: for example, the compressors of air-energy water heaters mostly use air-conditioning compressors, which cannot operate reliably in harsh environments in summer and winter; the heat exchangers (condensers) of air-energy water heaters are common The inner disc type or outer disc type is adopted, together with polyurethane overall foaming. When the coil tube is corroded, the entire water tank will be scrapped; the throttling device of the air energy water heater generally adopts a capillary tube, which cannot effectively adjust the superheat of the evaporator under non-standard conditions. ; The evaporator of the air energy water heater generally adopts a single proces...

Problems solved by technology

[0002] At present, there are many problems in the air-energy water heaters on the market: for example, the compressors of air-energy water heaters mostly use air-conditioning compressors, which cannot operate reliably in harsh environments in summer and winter; the heat exchangers (condensers) of air-energy water heaters are common The inner disc type or outer disc type is adopted, together with polyurethane overall foaming. When the coil tube is corroded, the entire water tank will be scrapped; the throttling device of the air energy water heater generally adopts a capillary tube, which cannot effectively adjust the superheat of the evaporator under non-standard conditions. ; The evaporator of the air source water heater generally adopts a single-flow design, and the system extension resistance is relatively high; the defrosting system of the air source water heater only relies on temperature single-factor adjustment and other disadvantages

These problems ultimately lead to the inability of the entire air energy water heater system to operate safely and efficiently, and the lifespan is short and the energy saving coefficient is low
