What is the heating principle of the non hot water dispenser?
Knowledge expansion:Effluent principle:The principle of water circulation inside the drinking water dispenser is realized by negative pressure bottle bottom is sealed and inserted into the drinking machine, its internal pressure less than atmospheric pressure outside, the bottle of water will not flow out, when the user is connected to the water tank, the water level dropped, air from the surface into the bottle, the a bottle of water into the water tank.If the water bottle breaks or cracks, the outside air enters the water bottle, which increases the pressure in the bottle, destroys the pressure balance, and causes the water tank surface to rise.
The heating system is divided into internal heating type and external heating type. The internal heat is through the stainless steel electric heating tube to heat the water directly in hot pot, external heat is ohmic heating in hot pot through the external heater to heat transfer through the heat tank of stainless steel, to heat the water in the tank, the external insulation layer to reduce heat loss. By contrast, the internal heating has the advantages of high thermal efficiency, fast heating and small power consumption, but the heating tube is easy to scale and difficult to clean; the external heating has large heat loss, and the heating is slower, but less fouling and no noise.
Refrigeration principle:Principle: compressor refrigeration compressor refrigeration system consists of compressor, condenser, evaporator and capillary of four parts, among them with pipes connected to form a closed system, the refrigerant circulating in the system, constantly change, and energy exchange with the outside world, so as to achieve the purpose of refrigeration.The working process is: the compressor suction at low temperature and low pressure refrigerant vapor generated in the evaporator, and keep the low pressure in the evaporator liquid refrigerant in the evaporator to create constantly boiling under low temperature conditions (isobaric process); inhalation of the vapor compressed, temperature, pressure (isentropic process), high temperature and high pressure steam into the condenser under constant pressure, the cooling medium (water or air) cooling, heat, temperature, and further condenses into liquid (isobaric process), discharged from the condenser; the high-pressure liquid refrigerant passes through the throttle valve, because of resistance and the pressure drop, resulting in part of the refrigerant liquid vaporization, absorbing the latent heat of vaporization. Make its own temperature decreased, a wet steam, low temperature and low pressure in the evaporator; refrigerant in the evaporator. Liquid in the case of constant pressure, absorbed by the cooling medium (air, water, etc.) the heat (ie, the amount of cooling) and vaporization, forming a low temperature, low pressure, steam is sucked by the compressor, so the cycle.
