Phase change heat storage-type instant heat pump miniature water heater

Abstract

The invention provides a phase change heat storage-type instant heat pump miniature water heater used for providing sufficient hot water for users in time. The phase change heat storage-type instant heat pump miniature water heater is characterized in that the miniature water heater comprises a water tank unit, a thermal storage heating unit, a heat pump heating unit, a signal measuring unit, a protection unit and a control unit; the water tank unit is provided with a water tank used for storing water, a safety valve arranged at the top of the water tank, an electromagnetic valve arranged on awater inlet pipeline of the water tank and a current equalizer arranged at the water inlet position of the inside of the water tank; the thermal storage heating unit comprises a plurality of thermalstorage material layers which are perpendicular to the extension direction of the water tank and are further arranged inside the water tank at certain intervals; the heat pump heating unit comprises acompressor, a condenser, a drying and filtering device, a throttling part and an evaporator which are connected in sequence; the signal measuring unit comprises a plurality of temperature sensors which are distributed on the tank wall of the water tank in the extension direction of the water tank, a water level gauge which is connected with the water tank in parallel and pressure sensors which are arranged at the two ends of the compressor; and the protection unit sends out an alarm or executes protection operation according to the detection result of the signal measuring unit.

Description

technical field [0001] The invention belongs to the technical field of water heater equipment, and in particular relates to a phase change heat storage type instant heat pump small kitchen treasure. Background technique [0002] Today, energy shortage and environmental pollution are two prominent problems facing the sustainable development of all countries, which have attracted widespread attention from all over the world. And along with the raising of people's living standard, the electricity consumption that is used for air-conditioning, heating and making domestic hot water constantly climbs. Therefore, the continuous development and effective utilization of renewable energy has become an effective way to alleviate the global energy crisis. [0003] Air energy, that is, the low-grade thermal energy contained in the air, belongs to clean energy like water energy, wind energy, solar energy, and tidal energy. An important issue for workers. Among them, the air source heat...

Problems solved by technology

[0005] The heat storage electric heating kitchen treasure needs to be heated by electricity for a period of time before the user can use it, and the water tank of the heat storage electric heating kitchen treasure is prone to fouling, which affects the service life

Although the instant electric heating kitchen treasure can produce hot water immediately, the water output is limited, and the water temperature is low in the state of large flow water, which greatly reduces the user experience

The biggest disadvantage is that whether it is a heat storage type or an instant electric water heater, all of them use electric heating and heating, which has high energy consumption, short life and poor safety, which is not conducive to the sustainable development of energy.
