Coolant instant heating water heater

Abstract

The invention provides an instant refrigerant water heater, which comprises a compressor, a water heat exchanger, an air-cooled evaporimeter and a throttle that are connected in series. The invention is characterized in that, the water heat exchanger comprises at least one refrigerant pipeline, which is in form of coiled pipe; on the refrigerant pipeline, a water pipe is looped for carrying out water heat exchange; the water pipe has a water inlet and a water outlet, which form the heating channel of the water; the refrigerant pipeline and the pipe are connected to form a refrigerant circulation system. The advantages with the invention are that the refrigerant pipeline of the water heat exchanger is located in the water pipe for exchanging heat with the water, the heat-exchanging area is big, the heat transmission rate is high, and the efficiency is high; the invention can be used once the heater is on, is very easy to use. In the water heat exchanger, the refrigerant pipeline is arranged in the water pipe, and a refrigerant leaking arrangement is provided, which can prevent the water from being contaminated. The invention saves 75% energy than an electric water heater, and is free from any accident such as personal damage due to current leakage or any gas poisoning, is energy-saving, environmental friendly and safe to use.

Description

【Technical field】 [0001] The invention relates to an electrical appliance for heating water, in particular to a water heater which utilizes the state change of refrigerant to heat water. 【Background technique】 [0002] At present, most of the water heaters on the market rely on electric energy, solar energy, and natural gas combustion heat to produce hot water. Water heaters that rely on electric energy consume a lot of electricity and are expensive to use. The water in the water tank is heated for a period of time to make hot water, and the solar water heater cannot be used around the clock, which is very inconvenient to use. Water heaters burning natural gas are prone to gas leakage accidents, endangering human life. [0003] According to the characteristics of the state change of the refrigerant, it is a research direction to make full use of it to release a large amount of condensation heat to heat the cold water when it condenses, and to make a safe, efficient, energy-...
