Device for producing drinking water by using recovered waste heat of central air conditioner

Abstract

The invention discloses a device for producing drinking water by using recovered waste heat of a central air conditioner, which comprises a heat interchanger and a thermal insulation water tank. The heat interchanger is arranged between a compressor and a condenser of the central air conditioner; the inner wall of a stainless steel shell of the heat interchanger is provided with a first thermal insulation material; the centre of the stainless steel shell has a hollow structure; an exhaust pipe which is connected with the compressor is positioned on the middle part of the hollow structure; the hollow structure has a conical structure with a big top and a small bottom; the capacity of the hollow structure is controlled to be between 4 and 6 L; a ratio of the diameter of an upper top surface to the diameter of a lower bottom surface of the hollow structure of the heat interchanger is 1: 2-3; and the upper and lower parts of the hollow structure are sealed. By adopting the design that the conical hollow structure is formed in the heat interchanger, the tap water heated by the heat interchanger boils to meet the drinking requirement, so the device is very suitable to be used at places, such as airports, stations, emporiums and the like with large flows of people, free boiled water (drinking water) supply to the public to meet the demands of the public and central air conditioners.

Description

technical field [0001] The invention relates to a drinking water production device, in particular to a device for producing drinking water through central air-conditioning waste heat recovery. The drinking water is heated to the boiling point through the heat exchanger, which is especially suitable for the waste heat recovery of large central air-conditioning units. Background technique [0002] The existing central air-conditioning waste heat recovery devices are mainly waste heat recovery equipment developed to meet the demand for hot water in hotels, hotel rooms, restaurants, saunas, swimming pools, etc. The hot water supplied is about 50 °C, and these waste heat recovery equipment are better. It effectively solves the place where central air-conditioning waste heat is recovered to produce hot water for bathing. Chinese invention patent application 200510032362.X discloses a method for processing hot water by utilizing waste heat of a central air conditioner. 50% to 100...

AI Technical Summary

Problems solved by technology

Solve the problem of huge energy waste and serious heat pollution caused by the heat discharged by the central air-conditioning chiller during cooling, and the use of electricity or boilers to supply boiling water requires a large amount of fuel, resulting in double waste of energy and double pollution to the environment
