Efficient energy-saving air energy water heater

Abstract

The invention discloses an efficient energy-saving air energy water heater. The efficient energy-saving air energy water heater comprises an evaporator, a compressor, a condenser, a filter and an expansion valve which are connected in a circulating mode through a refrigerant pipeline, and further comprises a water tank, a plurality of partitions, and a condensing tube, wherein a hot water outlet tube is arranged at the upper end of the water tank; a cold water inlet tube and a refrigerant inlet are arranged at the lower end of the water tank; the upper end of the cold water inlet tube communicates with a spherical part; a first sleeve sleeves the cold water inlet tube; a second sleeve sleeves the first sleeve; the partitions are used for dividing the inner part of the water tank into a plurality of spaces, and an arc-shaped hole is formed in each partition; the condensing tube passes through the partitions from bottom to top, the part, positioned in each space, of the condensing tube communicates with a first branch tube; and the first branch tubes extend out of the water tank and communicate with a second branch tube outside the water tank. According to the water heater disclosedby the invention, the spherical part, the first sleeve and the second sleeve are equipped with a plurality of guide holes for reducing flow speed of cold water entering the water tank, so that mixingspeed of original hot water in the water tank and cold water is reduced, and a hot water utilization rate is increased.

Description

technical field [0001] The invention relates to the field of water heaters, and more specifically, the invention relates to a high-efficiency and energy-saving air energy water heater. Background technique [0002] Air energy water heaters, also known as heat pump water heaters, or air source water heaters, are devices that use the working principle of heat pumps to absorb heat from the air to produce hot water. The air-energy water heater transfers the heat in the environment to the water by allowing the refrigerant to continuously complete the thermodynamic cycle of evaporation, compression, condensation, throttling, and re-evaporation. The power consumption of air-energy water heaters is usually only a quarter of that of electric water heaters, and it does not need to rely on sunlight for heating like solar water heaters. Since the work of air-energy water heaters is realized through heat exchange with refrigerants, electric heating elements are not required. In contact ...

AI Technical Summary

Problems solved by technology

However, the existing air-energy water heaters only heat the cold water in the entire water tank to the required temperature, and for the situation that the water consumption is small and the whole tank of hot water cannot be used up, the existing air-energy water heaters have no better means to deal with it. In this case, the whole tank of water is still heated, resulting in waste of hot water and energy, and increasing the user's use cost

At the same time, the incoming water of the existing water heater directly enters the water tank at a relatively high speed through this water heater inlet pipe assembly, resulting in serious mixing of hot and cold water, and a large drop in the temperature of some hot water, resulting in the amount of hot water that can be directly used. reduce
