Heat Pump Tips: Heat Pump In What Refrigerant
Heat Pump Network HC Heat Pump ?? Is from the nature of air, water or soil for low heat, acting through the power output can be used by people of high grade heat equipment is a Energy , Environmental protection , Clean heating and hot water equipment.
Heat Pump Is the use of refrigerant gas at room temperature under ultra-low temperature or pressure of liquid properties, the low-temperature heat collected through the compressed gaseous refrigerant of high temperature heat source to a device.
Short, is a heat pump using refrigerant heat conversion device.
So in theory, used in refrigeration system refrigerant, heat pump systems can all use, such as R22, R407c, R134a, ammonia can also can be the same as using a hybrid cooling system refrigerant. But specific to the actual situation, to consider the heating temperature, heating efficiency, and need to be carefully selected refrigerant.
Heat Pump Tips: We all know, water flows. And wishing to upgrade or transfer of water shall be to rely on a power-driven pumps. Similarly, heat can spontaneously transfer from the hot object to cold objects, and wish to transfer from the cold objects to hot objects, they must rely on using a power-driven devices? Heat pump. This is elaborated in the second law of thermodynamics: Heat can not spontaneously, without paying for it to spread from high-temperature object at low temperature objects. When the heat pump heat from low temperature objects in the object transmitted to the process of high temperature, low temperature objects in the end, due to heat loss caused by cooling effects of high temperature objects in the end, be due to thermal heating effects arising. Therefore, the heat pump work in the process of cooling and heating two effects is also co-exist. In a nutshell, is a process, two kinds of effects. However, in practice, or refrigeration, or use their heating, cooling or heating of its rotation, or use the same cooling and heating. At the same time except for cooling and heating, heat pump for cooling or heating alone, the corresponding effect is not an alternative to use.
Long time, the heat pump air-conditioning cooling function in the areas of application of a wide range of functions and its application of heating is relatively delayed and much less. Reason is not complicated, the role of natural cold source is very limited, it is the pursuit of artificial cold source, people development and the gradual improvement of the refrigerator? Application of its cooling function of heat pump. The heat is through firewood burning coal and oil and gas and other easily obtained. Unnecessary to spend too much money to purchase sophisticated equipment such heat pumps, and delivery of higher tariffs. Seventies of last century Energy Crisis, people began to use low-grade heat pump can pay attention to. China started from the nineties, as the first, the introduction of heat pump manufacturing technology, to improve performance, lower prices; second, awareness of environmental issues; third, to improve the situation of power supply, electricity and other reasons the policy shift , heat pump heating function of a concern. Heating And Cooling air source heat pump dual-function applications, better water Water Source Heat Pump Began in the air conditioning or heating system in use.
Is called being determines consciousness, as has long been in the air conditioning, the heat pump is mainly used for cooling and refrigeration theory writings did so for the main line, usually only at the end of a separate heat pump section, a brief statement of its heating functionality. Was also more use of air conditioning and refrigeration or air conditioning cold source in the name. However, in the heat pump in the name of the monograph, then its heating function as the main content. For heat pumps, in fact, there are two narrow and broad understanding. In accordance with the narrow understanding, only to heating or heating and cooling for the purpose only when called heat pump. And define, to air or water for the low-temperature heat source heat pump for air-source heat pump and water pump. Equipped with a reversing valve, cooling and heating functions are also called “heat pump” or “with a heat pump” and so on. The broad sense, which includes refrigeration heat pump functions, including heating, or cooling and heating. Refrigerator is actually used as a cooling pump. Can also be said, refrigerator or heat pump, or rather, a type of refrigerator is a heat pump. Therefore, understanding the concept of air conditioning should be unified for the air conditioning heat pump, air conditioning and heat pump rather than discrete.
