Cold and hot water supplying method of energy-saving type double-temperature drinking machine

Abstract

The invention belongs to the technical field of a cold and hot water supply method of a two-temperature water fountain. The cold and hot water supply method of the energy-saving type two-temperature water fountain comprises the following step: a compressor, a hot liner or a gas cooler, an expansion valve, and a cold liner or an evaporator in a transcritical CO2 heat pump circulating system are connected in series through pipelines to form a circulating loop, wherein the hot liner and the gas cooler are in parallel connection; and the cold liner and the evaporator are in parallel connection. In the method, the carbon dioxide heat pump system is introduced into the water fountain to form a transcritical carbon dioxide heat pump water fountain which can transfer heat in cold water to hot water, thereby simultaneously supplying the cold water and the hot water and exerting the advantages of the carbon dioxide heat pump system in energy conservation and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of a method for supplying cold and hot water by a dual-temperature water dispenser. Background technique [0002] Due to the increasingly serious environmental problems such as the destruction of the atmospheric ozone layer, global warming, and climate anomalies, energy conservation and environmental protection have become issues of common concern to all mankind. [0003] With the improvement of people's living standards, water dispensers have been popularized in people's life and work. At present, the annual output of water dispensers in my country has reached 30 million units, and people's requirements for the performance of water dispensers are getting higher and higher. , but also to provide cold water. The heating power of the water dispenser is generally 300-1000w, and the cooling power is generally 80-100w. A family consumes 0.5-1.5 degrees of electricity per day on a water dispenser, and a medium-si...

Problems solved by technology

The cooling capacity of semiconductor refrigeration is relatively small, while the refrigerant used in ordinary compression refrigeration is Freon, which can only provide hot water below 30-40°C, which cannot meet the demand. Electric heating is needed to supplement heating, which makes the water dispenser device complicated. And it has a certain destructive effect on the environment
