The heating and cooling heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source, and is also a new energy technology that has attracted a lot of attention worldwide. It differs from the well-known mechanical equipment, which can increase the potential energy"Pumps"; A heat pump usually first extracts inferior heat energy from natural air, water or earth, then performs work by electricity, and then provides people with available energy that can be used. of high quality thermal energy.
What is the working medium of the heating and cooling heat pump?
What role does the heating and cooling heat pump play?
What do you know about heating and cooling heat pumps?
The working medium of the heating and cooling heat pump used to be Freon, but since Freon adversely affects the Earth's atmospheric ozone to protect the Earth's ecological environment, in addition to improving the cooling coefficient of the heat pump and effective use, science is also committed to new technologies in various countries. With the development of quality, the working fluid was used as a replacement for Freon. However, the work equipment of most Chinese manufacturers today is still R22, and the era of using environmentally friendly work equipment R417A and 134A has not yet arrived. Some countries, such as Japan, have taken the lead in using CO2 as a working medium to avoid damaging the ozone layer. (Therefore, the copper pipes must be firmly connected during installation to prevent R22 from leaking.) In addition, the above R22, R417A, 134A and CO2 do not harm the human body. Even if there is a leak, all the equipment is still safe.
The low temperature heat sources normally used in heat pumps for heating and cooling are the media around us. Air, river water, seawater, municipal wastewater, surface water, groundwater, treated water, fire pits or working fluids, which are discharged from industrial production plants these working fluids often have similar temperatures to the surrounding medium. The operating principle of the heating and cooling heat pump is the same as that of the compression chiller. In order to fully exploit its efficiency, the small air conditioner is cooled with the same equipment in summer or heated in winter. When heating in winter, the evaporator and condenser in the air conditioning system are exchanged via a switching valve.
Heat pumps for heating and cooling are an intelligent, efficient and versatile solution for year-round heating, cooling and hot water supply solutions. In addition to their flexibility and wide application, they are energy efficient and environmentally friendly, with advanced EVI technology and green refrigerant R32/R410A. So you can enjoy a comfortable home and save energy at the same time.

With the continuous improvement of living standards, there are more and more users of heating and central air conditioning. Central heating users do not need to worry about the choice of equipment, while household heating users need to face a dazzling array of hot and cold equipment, which is difficult to carry out. choose. Heating and Cooling Heat Pumps are constantly entering the public's field of vision, and are sought after by many users because of their environmental protection and energy-saving features. But what else should you know before choosing a Heating and Cooling Heat Pump?
How energy efficient is the Heating and Cooling Heat Pump?
How to save resources when cooling with Heating and Cooling Heat Pump?
How to save resources when heating with Heating and Cooling Heat Pump?
The Heating and Cooling Heat Pumpcan adjust the indoor temperature by absorbing the heat energy in the air and then transferring it to the water for heat exchange. In summer, it is cooled by fan coil unit, and in winter, it is heated by fan coil unit, floor heating or radiator. It has a dual-purpose function. Heating and Cooling Heat Pump can also be connected in areas with better environment. Domestic hot water, and even the water heater are saved.
Heating and Cooling Heat Pumprefrigeration is to cool the circulating water in the pipeline into chilled water through the heat pump unit. The outlet air temperature of the indoor fan coil is between 15°C and 20°C. The chilled water is circulated into the room for heat exchange, and the evaporator The heat absorption in the room transfers the heat in the room to the circulating water in the pipeline, and then the circulating water after the heat absorption is brought to the heat exchanger configured by the heat pump unit through the operation of the water pump for heat exchange, and finally the heat pump host discharges the heat to the air In the cycle, this process is repeated to achieve the effect of indoor cooling. However, it should be noted that after the circulating water in the pipeline is cooled by the Heating and Cooling Heat Pump, the temperature can be kept stable for a long time without heat exchange, and there is no short-term loss of cooling capacity. Energy consumption will also be lower.
Heating and Cooling Heat Pump heating is to replace the collected heat into the heating pipeline through the heat pump unit, and then deliver the water to the floor heating, fan coil and radiator at 35°C-45°C, 40°C-50°C and 55°C respectively. The heat is released in the middle, so as to achieve the effect of indoor heating. Because the air energy heat pump adopts frequency conversion technology and jet enthalpy increasing technology, it has a high energy efficiency ratio, and can obtain more than three times the heat energy from the low temperature environment, and the energy saving performance will be much higher than that of direct conversion of electric energy into heat energy.

As heat pumps are more and more popular in the market, people want to know if it's worthy to use it.
Of course Yes! Heat pump water heaters are worth the cost.
More Efficient
Heat pumps are significantly more energy efficient than normal electric or gas hot water heaters because instead of using energy to generate new heat, they collect existing ambient warmth and transfer it to the water. This efficiency can save you hundreds of dollars on energy bills each year.
Tax Incentives and Rebates
With tax incentives and state-sponsored sales rebates, energy efficient heat pump water heaters can actually be a more affordable choice than most homeowners would expect. Though the upfront cost is high, most homeowners pay back heat pump water heaters within the first or second year alone. And heat pump water heaters are long-lasting – a good, well-maintained heater can last between ten to fifteen years.
Environmentally Friendly
Because heat pumps are more energy efficient than conventional hot water heaters, they do not use as much electricity and/or natural gas, which reduces greenhouse gas emissions. In fact, it estimates that if all residential water heaters were replaced with heat pump water heaters, there would be up to 140 billion pounds of greenhouse gas emissions are saved annually.

Heat pumps can both heat and cool because they are made with a component called a reversing valve. This valve allows the heat pump to change the flow of refrigerant in the system, so it can operate in either cooling or heating mode. During the winter, in heating mode, the heat pump absorbs heat from the surrounding air, concentrates it in the heat exchanger and blows the air into your home. In the summer months, the heat pump removes the heat and humidity from your indoor air and transfers it to the outside.
