Pressurized fluorine water circulation air energy hot water method and air energy water heater

Abstract

A pressurized fluorine water circulating air energy hot water method is used for controlling the heating of water by a pressurized water tank, a subcooling heat exchanger, a low temperature heat supply heat exchanger, a sensible heat heat exchanger and a circulating water pump. First, the cold water enters from the bottom of the pressurized water tank, and the hot water comes out from the high end of the pressurized water tank, so that the stratification of hot water in the pressurized water tank is obvious, and the energy consumption required for heating hot water is reduced. Static heating is carried out in the pressurized water tank through the sensible heat exchanger, and the layered heating of the coil makes full use of the sensible heat provided by the heat shrinking machine, which slows down the overheating phenomenon during the return air process, avoids the loss of sensible heat and improves the efficiency. efficiency. The low-temperature heat supply heat exchanger cooperates with the subcooling heat exchanger for water circulation heating, and the subcooling heat exchanger can supercool the cold water when the water heater enters the water, improving the energy efficiency of the water heater and making the water heater more energy-saving.

Description

Technical field [0001] The present invention relates to a water heater controller, and more particularly, to a pressurized hot air circulation type fluorine method. Background technique [0002] Air heater and heater circulation cycle divided fluoro heaters, water heaters, air circulation and the host are connected through the tank pipe, by the circulation pump draws water tank between the device and the cycle of heating the heating water tank. Since the circulation water heater instead of using a direct electric heating element, electric water heater, it is relative, to avoid the risk of leakage, safety performance, since the regenerative water heater is a water circulation, the heating can be started automatically depending on the temperature in the tank, the amount of high water . [0003] However, conventional water circulating heaters when cold water into the water tank, resulting in the phenomenon of mixing water, reducing the energy efficiency of the water heater, the wate...

AI Technical Summary

Problems solved by technology

[0003] However, in existing water circulation water heaters, cold water is injected into the water tank during water supply, resulting in mixed water, which reduces the energy efficiency of the water heater, and consumes more electricity when the water temperature rises to the preset value; the heating is started only when the water temperature is lower than the preset value by 5°, and the heating is missed. The optimal heating time is obtained, and multiple heat exchange operations are required to heat the water to the preset temperature value. The hot water process takes a long time, resulting in the limitation of the water supply of the water heater.
