Heard of air source heat pump, what is carbon dioxide heat pump and air conditioning? What is the principle? Why use carbon dioxide? Please answer, thank you
Other features include:(1) do not destroy the ozone layer.(2) the global warming potential (GWP) was 1.(3) easy to obtain (can be obtained from industrial waste gas), very low cost.(4) there is no short, medium and long-term harm to human health and living environment, so there is no need to recycle or recycle it.(5) non-toxic and will not break down irritating substances.(6) non flammable (Non-Flammable) and non explosive (Non-Explosive).(7) excellent thermodynamic properties.(8) the CO2 refrigerant system can use traditional mineral oils.
Due to the large demand for hot water in daily life in temperate to cold countries, the energy consumption of domestic hot water accounts for 30% of household energy expenditure, and most of them are hot water boilers. High latitude countries pay special attention to issues such as ozone depletion and global warming, so advanced developing countries, such as Europe and Japan, are eager to develop CO2 heat pump water heaters.
CO2 heat pump water heater:Heat pump water heater for domestic hot water supply, heating, air conditioning and heating into the interior of the cold winter air, water or other boiler preheating process, the method is quite efficient and economic benefits.The advantages of heat pump water heater contains natural gas needed to reduce the amount of heating and fuel and reduce pollution to the outside of the condenser heat radiation, its application objects include: warm water (40~60 degrees C) demand, air conditioning demand (or not) of the place, the user (boiler make-up water, shower preheating) sports venues residential facilities, dormitories, hotels, hospitals, and spa with hot water and heating demand places.
CO2 heat pump is the use of CO2 as a refrigerant heat pump or air conditioning, ordinary heat pump generally adopts freon as a refrigerant, the working principle is basically the same, all belong to the steam compression type, but also slightly different, CO2 heat pump belongs to the supercritical cycle, which in the end is not CO2 condenser, is condensed into liquid, and Freon the refrigerant in condenser end is condensed into liquid and then throttle.
