Household variable-capacitance stepless regulation instant heat-pump water heater

Abstract

The invention discloses a household variable-capacitance stepless regulation instant heat-pump water heater which comprises a refrigerant circulating system, a water supply system, a control system and the like. The control system comprises a defrosting detection sensor, a water flow detection sensor, a water temperature sensor, a compressor variable-capacitance stepless regulation controller and the like, a digital scroll compressor and a fuzzy controller are used, and a balancing short pipe provided with a two-way electromagnetic valve is connected between a condenser and an evaporator, so that the compressor can be immediately started after stopping. The fuzzy controller is used for accurately controlling water temperature by combining compressor variable-capacitance stepless regulation and water flow regulation. The household variable-capacitance stepless regulation instant heat-pump water heater is high in energy efficiency ratio and fine in energy-saving effect, starting current is reduced by means of low-load starting, other household electric appliances cannot be affected in use, high-voltage alarm is avoided and normal operation of the water heater is ensured by combining variable-capacitance stepless regulation and water flow regulation, a water tank is omitted, space is saved, and the water heater is instant available so that a user does not need to wait for water using time.

Description

technical field [0001] The invention relates to a water heater, in particular to a household variable capacity stepless adjustable heat pump water heater. Background technique [0002] Heat pump water heaters use the reverse Carnot cycle principle to transfer heat from a low-temperature environment to a high-temperature environment (hot water) by consuming a small amount of electricity. It is an energy-saving product for producing sanitary hot water, with an annual energy efficiency ratio of about 3.0. At present, there are two types of heat pump water heaters: circulation heating type and one-time heating type. The former heats the water in the storage tank through circulation, and finally raises the storage water temperature to 50~60°C; Water (temperature 5~35°C) is heated to 45~60°C at one time. The one-time heating type is divided into two types: direct heating type and instant heating type. The water is sent to the insulation water tank first, and then sent to the user...
