Phase-change energy storage double-evaporator solar heat pump heating system and control method thereof

The invention relates to a phase-change energy storage double-evaporator solar heat pump heating system. The phase-change energy storage double-evaporator solar heat pump heating system aims to overcome the defects that a water tank of an existing solar water source heat pump heating system is not high in heat storage capacity, circulating water of the system is prone to freezing in extreme weather and operation reliability is low. A phase-change energy storage water tank is adopted to increase the heat storage capacity, a cylindrical phase-change unit is developed to enhance the heat exchange effect, double evaporators (a water-cooled type evaporator and an air-cooled type evaporator) are adopted, and when the energy efficiency value of the system in a water-cooled mode is lower than that of the system in an air-cooled mode under the same working conditions as the heat storage capacity of the water tank is insufficient or it is cold weather, the system can be switched into an air-cooled evaporator mode to be maintained to operate stably and efficiently. An intelligent control algorithm is developed, and automatic control is achieved according to the system energy efficiency and the temperature of outlet water of a heat collector. The system is a heating system which is technically feasible, convenient to control and high in operation efficiency and saves operation expenses. The system is particularly suitable for the areas with dry climate and rich solar energy.

Production process for ham smoked by bamboo leaves

An embodiment of the invention discloses a production process for ham smoked by bamboo leaves. The production process comprises the following steps of (1) selecting raw materials; (2) scraping a leg green body; (3) pickling: adding salt for more than 5 times, controlling a total amount of the salt at 45-50 g salt per net fresh leg and a pickling time at 25-50 days; (4) washing and drying in the sun: immersing the pickled pig leg in running water of mountain stream formed by flowing natural spring water, immersing and washing for 12-24 hours slowly with the spring water; (5) smoking and fermenting by the bamboo leaves: arranging a smoking room in a mountain with cool and dry climate that a temperature is not higher than 35 DEG C and a humidity is between 60-85% all the year round; hanging the washed and dried leg in the smoking room; burning moso bamboo leaves completely to make light smoke; introducing the light smoke into the smoking room; smoking and fermenting time for 3-6 months, moisture of the ham being 40-50% when the smoking and fermenting process is finished; (6) taking the ham off from a shelf and classifying; and (7) stacking for preservation. According to the production process, low salt pickling and cold smoking with light smoke of the bamboo leaves are adopted, so that the processed ham is fermented under low smoke, is not dry or hard, and has the fragrance of the bamboo leaves with a mellow taste.
