Multifunctional outdoor unit of air energy water heater

Abstract

The invention discloses a multifunctional outdoor unit of an air energy water heater. The outdoor unit comprises a support, a box body is arranged on the support, and the right end surface of the boxbody is movably connected with a first air plate; vent holes are uniformly distributed in the first air plate; a refrigerant heat exchange pipe is arranged in the box body on the left side of the first air plate; a ventilation hopper is arranged on the box body on the left side of the refrigerant heat exchange pipe; the left side of the ventilation hopper is connected with a first ventilation pipeline, the first ventilation pipeline is connected with a second ventilation pipeline and a third ventilation pipeline through a first electric three-way valve, a first exhaust fan is arranged on the second ventilation pipeline, and the second ventilation pipeline is connected with a fourth ventilation pipeline and a fifth ventilation pipeline through a second electric three-way valve. The air conditioner outdoor unit has the beneficial effects that the air flowing efficiency is high, the heat exchange efficiency is high, heat absorbed air is convenient to use, the interior of the outdoor unitis not prone to freezing in winter, the blowback ash removal effect can be achieved, the outdoor unit can work normally, and the service life is long.

Description

technical field [0001] The invention relates to an outdoor machine, in particular to a multifunctional outdoor machine of an air energy water heater. Background technique [0002] The air source water heater works according to the "reverse Carnot" principle. Specifically, the "outdoor unit" acts as a heat exchanger to absorb heat from the outdoor air, heat the low boiling point working medium (refrigerant) and evaporate it, and the refrigerant vapor is compressed The machine compresses and heats up and enters the water tank, releases heat to the water in it and condenses and liquefies, then throttles down and lowers the temperature and returns to the outdoor heat exchanger to enter the next cycle. [0003] However, the existing outdoor units have the following technical problems during use: first, most of the existing outdoor units use fans to blow the air into the outdoor unit to contact the refrigerant heat exchange tubes, and transfer the heat in the air to the refrigeran...

AI Technical Summary

Problems solved by technology

[0003] However, the existing outdoor units have the following technical problems during use: first, most of the existing outdoor units use fans to blow the air into the outdoor unit to contact the refrigerant heat exchange tubes, and transfer the heat in the air to the refrigerant for heat exchange. In the refrigerant in the tube, because the air is in contact with the refrigerant heat exchange tube under the action of the fan blowing, the efficiency of the air flow is low, resulting in low efficiency of heat exchange, and the fan blades are large in volume, and there is noise during high-speed rotation. Big disadvantage; second, in the process of using in hot weather, the outdoor unit acts as a heat exchanger to absorb heat from the outdoor air, and the air temperature after absorbing the heat is lower, which can be used for indoor cooling, but it is not necessary to cool down in cold weather or indoors When the outdoor unit absorbs heat, the indoor does not need the air after the outdoor unit absorbs heat, but the air after the existing outdoor unit absorbs heat is inconvenient to use; third, during the use of the outdoor unit in winter, the moisture in the air is easy to enter the outdoor unit. Icing on the hole, fan and refrigerant heat exchange tube, for the icing on the fan, it will greatly affect the service life of the fan, the heat exchange effect of the refrigerant heat exchange tube is poor, and when the icing is serious, the ice will cause the air inlet hole and the refrigerant exchange The blockage of the heat pipe will cause the air to be unable to circulate, or cause the mesh and the refrigerant heat exchange tube to be deformed or damaged, the fan will be stuck and unable to rotate, resulting in damage to the fan blades, burn-in, etc., all of which will cause the outdoor unit to fail to work normally; After the machine is used for a long time, dust will accumulate on the fan and the refrigerant heat exchange tube in the outdoor unit, the fan rotation will also be affected, and the heat exchange efficiency between the refrigerant heat exchange tube and the air will be reduced
