Combined equipment of heat pump water heater and water dispenser

Abstract

The invention discloses equipment combining a heat pump water heater and a drinking fountain. The equipment comprises a compressor, a four-way valve, an outdoor heat exchanger and a pressure-bearing water tank for the exchanger which are connected through a pipeline, wherein a water tank heat exchanger is arranged in an inner cavity of the pressure-bearing water tank; an input end of the water tank heat exchanger is provided with a hot drinking water part with a hot drinking water heat exchanger; an output end of the water tank heat exchanger is provided with a cold drinking water part with a cold drinking water heat exchanger; and the water tank heat exchanger, the hot drinking water heat exchanger and the cold drinking water heat exchanger form a refrigerant circulating loop together. The hot drinking water heat exchanger and the cold drinking water heat exchanger are arranged at the input and output ends of the water tank heat exchanger respectively; the drinking water is heated by heat exchange of high-temperature high-pressure refrigerants and cold drinking water is prepared by low-temperature low-pressure refrigerants in the process of preparing domestic hot water, so that dinking water with various temperatures can be provided, and the equipment can achieve multiple functions; and space occupied by indoor electrical equipment is saved, and the heat exchange efficiency is improved. The equipment has the characteristics of simple and reasonable structure, low energy consumption, long service life and low cost.

Description

technical field [0001] The invention relates to a combination device of a heat pump water heater and a water dispenser. Background technique [0002] At present, household water dispensers and heat pump water heaters are two separate electrical appliances. Chinese Patent Document No. CN102022828A disclosed a heat pump water heater equipped with a water dispenser on April 20, 2011, which includes a compressor, a throttling mechanism, and a fan. , an evaporator, a control system, an insulated water bucket and a condenser arranged in the insulated water bucket, characterized in that: the heat pump water heater body is also provided with a drinking water pipeline, which includes a hot water pipe and a cold water pipe, and the hot water pipe wears Through the thermal insulation bucket, part of the pipeline of the cold water pipe is close to the evaporator. It is said that it uses a heat pump water heater to heat / cool drinking water, which not only saves a separate water dispense...

AI Technical Summary

Problems solved by technology

However, this structure has the following disadvantages: 1. The water temperature in the thermal insulation bucket heated by the heat pump is generally below 55 degrees. and low heat exchange efficiency; 2. An electric heater must be equipped for electric heating, which consumes electricity; 3. The cold water pipe is placed near the evaporator and is cooled by radiation. The cooling effect is very limited, and the effect of cold drinking water in summer cannot be guaranteed.
