Intelligent hot water supply equipment based on air compressor afterheat recovery

Abstract

The invention relates to intelligent hot water supply equipment based on air compressor afterheat recovery. The equipment comprises an air compressor and a control cabinet; the air compressor is connected with a heat exchange water tank by a heat exchange plate; the heat exchange water tank is connected with a hot water storage tank; a first circulating water pipe between the heat exchange plate and the heat exchange water tank is connected with a first water pump; the heat exchange water tank is provided with a first temperature sensor, a first liquid level and a first water feeding valve; the hot water storage tank is provided with a second temperature sensor, a second liquid level and a second water feeding valve; a first control valve and a second water pump are connected between the heat exchange water tank and the hot water storage tank; and the first water pump, the first temperature sensor, the first liquid level, the first water feeding valve, the second temperature sensor, the second liquid level, the second water feeding valve, the first control valve and the second water pump are all in electric signal connection with the control cabinet. As the heat exchange water tank is matched with the hot water storage tank, the water temperature can be effectively controlled, and is nearly constant to bring convenience for users to directly use, the heat exchange efficiency is improved, and the working temperature of the air compressor is lowered.

Description

Problems solved by technology

Its disadvantages are: the waste heat of the air compressor in the factory is wasted everywhere and not fully utilized, and the domestic hot water used by the employees in the factory is often provided by the urban heating system, and the non-potable domestic hot water used by people It needs a suitable temperature for the human body. However, the temperature of the hot water in the above-mentioned air compressor waste heat recovery hot water supply device is not easy to control, and cannot maintain constant temperature and pressure. Therefore, it is inconvenient for users to use and cannot be directly used for washing, and the waste heat recovery effect is not good.
