Description

technical field [0001] The invention relates to a system and application for producing hot water by using a direct expansion solar heat pump to gasify liquefied petroleum gas, and belongs to the technical fields of solar heat pump technology and liquefied petroleum gas gasification. Background technique [0002] Liquefied petroleum gas is the main gas source of city gas in my country. In 2009, the national consumption of liquefied petroleum gas was 13.4 million tons. Among them, a large proportion of liquefied petroleum gas is gasified into a gaseous state after being heated and forced into a gaseous state in liquid form, and then supplied to gas users through the gas supply pipeline network. The traditional liquefied petroleum gas vaporizer mainly heats hot water with electricity, and the hot water (about 50°C) passes through the partition heat exchange method to vaporize the liquid liquefied petroleum gas into a gaseous state. Gasification of 1000kg of liquid liquefied pe...
