Solar heat pump technology (1) - heat pumps, solar energy, technology - heat pump industry : Eco Articles

See I am constantly on the
watch for interesting videos on
Alternative Energy Sources. This evening, I
discovered a very
fun piece of content that talks over Eco Energy Sources from a new
point of view. Today’s piece of content is titled Solar heat pump technology (1) – heat pumps, solar energy, technology – heat pump industry .

Article by hi joiney

network br br hc abstract technology is a good energy air conditioning refrigeration heating technology technology to solar energy thermal technologies can improve the efficiency of solar collectors and system performance while addressing the all weather heating problem therefore the research and development of solar is more and more attention this article discusses the principles of solar technology and features as well as providing hot water in the application and the present status and so on br br introduction br br with economic development and the advancement of technology energy and the environment is prominent in today 39 s world the two social problems promoting greater awareness of the importance of human energy while increasing emphasis on solar energy use and energy saving technology at present china mainly concentrated solar thermal use in passive solar house heating and water heaters to provide domestic hot water while active solar heating system developed by use of the relatively backward using energy saving devices and solar collector devices thermal storage system to link the way institutions can not only effectively overcome the solar energy itself is a thin and intermittent and can achieve high energy savings and reduction of environmental pollution purposes has great development potential applications technology is a good energy efficient hvac technologies is to use a small amount of power as a driver of high quality energy low grade from low temperature heat source efficiently absorb heat and transfer it to the high temperature heat source in order to achieve the purpose of to switch to low energy transfer coefficient can transfer coefficient for the high energy high grade energy conservation that improve the quality of energy technology as people get domestic hot water requirement is rising with intermittent difficult to meet the all weather characteristics of solar heating to solve this problem technology and solar energy combin ed is undoubtedly a good selection br br 1 the basic principles and types of br br is a reverse use of the refrigerator and refrigerator only work in different temperature range the working principle of system shown in figure 1 1 2 evaporator absorbs heat its high temperature low pressure superheated refrigerant gas in the compressor into high pressure and temperature through adiabatic compression of gas the constant pressure by the condenser for the low temperature high pressure liquid condensate thermal gasification of refrigerant release etc heat exchange with the condensing water so that condensation water is heated to hot water for users liquid refrigerant via step down after the throttle valve into low temperature low pressure insulating liquid into the evaporator absorbing heat at constant pressure heat and evaporation changes for the superheated steam to complete a cycle so the cycle keep the heat in the heat transfer to the condensate br br according to first law of thermodynamics there is qg qd a the second law of thermodynamics the electric power consumed by the compressor a play compensation so the refrigerant can be kept from the low temperature endothermic qd to the high temperature heat qg a rolling loop br br thus compressor power consumption is an important technical and economic indicators the general performance coefficient coefficientofperformance referred to as cop to measure the device 39 s energy efficiency which is defined as br br cop qg a qd a a 1 qd a br br obviously cop is always greater than 1 therefore the heat pump is an efficient energy saving device is implemented in the field of refrigeration and air conditioning building energy efficiency important way for conventional energy conservation air pollution and greenhouse effect mitigation play a positive role br br all types of evaporation and condensation heat pump has two temperature levels with expansion valve or capillary blood pressure refrigerant to achieve sa vings but different forms of pressure to increase mainly mechanical compression thermal compression and steam injection compression among them the mechanical compression heat pump also called electric heat pump is already widely used in building heating and air conditioning heat pump market in a dominant position thermal compression heat pump including absorption and adsorption of two types of which the water lithium bromide absorption and ammonia water absorption of hot water units have gradually embarked on the road of commercial development while the adsorption heat pump is still in the research and development phase but also must overcome the intermittent operation and system performance and cooling issues such as weight ratio of low to really applied to practical according to the different forms of heat source can be divided into air source heat pump water source heat pump ground source heat pump and solar heat and so on foreign literature usually groundwater heat pumps surfac e water and ground source heat pump heat pump referred to as ground source heat pump br br editor sub yoon

I am an expert from China Products, usually analyzes all kind of industries situation, such as ryobi cordless , drill sds bits.
