Embodiment

[0027] Example: using figure 1The process flow shown is calculated by heating 10 liters of boiling water per hour as an example. The water supply temperature used is 25°C, the water supply preheating temperature is 80°C, the boiling water temperature is 100°C, the boiling water vaporization rate is 1%, the electric heater input power is 0.288kw, the warm water output temperature is 50°C, and the cold water output temperature is 20 °C. Heat exchanger surface area 0.0342m 2 . The surface area of ​​the heat exchanger is taken as the total heat transfer coefficient of 0.02 cal s -1 m -2 ·K -1 calculate. If the heat pump efficiency COP is calculated as 1, compared with the water boiler without heat exchanger and heat pump, the energy saving rate is about 85%.

Abstract

The invention relates to an energy-saving type three-temperature-output water boiler, comprising a water supplementing device, an electric heating device, a heat-pump circulating system and a heat exchanger, wherein the heat exchanger and a heat pump are respectively used for recovering the heat from boiling water and warm water so as to heat newly-supplemented water. The energy-saving type three-temperature output water boiler is characterized in that the boiled water after high-temperature sterilization is output by three temperature modes such as a hot mode, a warm mode and a cold mode so as to meet the need of instantaneous drinking. In the energy-saving type three-temperature output water boiler, the boiled water is output instantaneously or cooled by section so as to obtain hot water, warm water and cold water; simultaneously, the heat released by two sections of cooling processes is used for heating the newly-supplemented water by the heat exchanger and the heat pump, so that the energy consumed by high-temperature sterilization is greatly reduced. In the energy-saving type three-temperature output water boiler, the cold / hot water heat exchanger is combined with a compressor, an evaporator and a condenser in the heat-pump system, and after a multi-way valve is arranged, the drinking water with three water temperatures such as hot water, warm water and cold water can be output instantaneously.

Description

technical field [0001] The invention relates to a water boiler, in particular to an energy-saving three-temperature output water boiler. Background technique [0002] Fresh water (tap water) is not suitable for direct drinking in most parts of China. Tap water usually needs to be boiled and sterilized before drinking. In fact, high-temperature boiling water is not suitable for immediate drinking. [0003] There are not many US or European patents directly related to energy-efficient water boilers. This may be because boiling water is not used much to sanitize drinking water in the US or Europe. Most of the patents related to this are for water disinfection or bacterial control, such as the US patent [publication number US6251279B1] and international patent application [publication number WO0163182A1] applied to large-scale water supply systems. A water heating device invented by a British inventor divides the electric water boiler into two parts so that it can heat the e...
