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.

The heating and cooling heat pump is a highly efficient, energy-saving device that makes full use of inferior thermal energy. Heat can be transferred spontaneously from a hot object to a cold object, but not spontaneously in the opposite direction.
How does the heating and cooling heat pump work?
What does the operating time of the heating and cooling heat pump have to do?
What is the function of the heating and cooling heat pump?
In the heating and cooling circuit of the heat pump, the heat Q0kcal/h is obtained from the low temperature heat source (outside air or circulating water whose temperature is higher than the evaporation temperature t0) and the mechanical work ALkcal/h is consumed, while the heat of Q0kcal/h is obtained from the low temperature heat source (outside air or circulating water whose temperature is higher than the evaporation temperature t0) and the mechanical work ALkcal/h is consumed. The heating system) provides the heat of Q1kcal/h, and the relationship between these heats corresponds to the first main law of thermodynamics, ie Q1=Q0+ALkcal/h
If the heating and cooling heat pump is not used and the heat is converted by mechanical work (or the high temperature heat source is heated directly by electrical energy, the heat obtained is ALkcal/h, and after the heat pump device is used, the high temperature heat source (heating system) receives more heat is obtained: Q1-AL=Q0, kcal/h This heat is obtained from a low temperature heat source, and this heat cannot be obtained without a heat pump device. Therefore, using a heat pump device can save fuel and use waste heat.
The working cycle of a heating and cooling heat pump is exactly the opposite of that of a thermal engine. A thermal engine uses the energy of a high-temperature heat source to generate mechanical work, while a heat pump transfers heat from a low-temperature heat source to a high-temperature object by consuming mechanical work.
If the heat pump and the heat engine have two identical heat source temperatures, the thermal efficiency of the heat engine cycle is η=AL/Q1; the energy index of the thermal engine cycle – the heat conversion coefficient φ=Q1/AL, i.e. φ=1/η. The value of η is always less than 1, so the value of φ is greater than 1.
If the refrigerator and the heat pump have two identical heat source temperatures, the relationship between them is φ=Q1/AL=(Q0+AL)/AL=e+1, where η is the refrigerator's cooling coefficient. It can be seen that the minimum value of the heat transfer coefficient φ η1 and in this limit case Q0 E0, that is, no heat is absorbed from the low temperature heat source.

How exactly does the heating and cooling heat pump work?
What is the basic principle of heating and cooling heat pump?
Will the floor height affect the installation of the heating and cooling heat pump?
The common heating and cooling heat pumps on the market are almost all of combined cooling and heating, which solves the problems of cooling in summer and heating in winter through a set of equipment. In some specific areas (the temperature is relatively high in winter), the air energy heat pump can also be connected to the domestic hot water tank to provide 24-hour uninterrupted hot water for the family, so the air energy heat pump can be used for cooling and heating, as well as cooling and heating. And with domestic hot water, but in order not to affect the heating effect, the domestic hot water is generally not combined.
Basic principle of heating and cooling heat pump: it is mainly composed of compressor, heat exchanger, axial fan, thermal insulation water tank, water pump, liquid storage tank, filter, electronic expansion valve and electronic automatic controller. After the power is turned on, the axial flow fan starts to operate. The outdoor air is heat exchanged through the evaporator. The air with reduced temperature is discharged from the system by the fan. At the same time, the working medium inside the evaporator is sucked into the compressor. The compressor compresses the low-pressure working medium gas into high-temperature and high-pressure gas and sends it to the condenser. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and sent to the user for use, The working medium is cooled into liquid, which flows into the evaporator again after throttling and cooling by the expansion valve. In this way, the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the insulation water tank gradually rises to about 55 ℃, which is just suitable for people to take a bath. This is the basic working principle of heating and cooling heat pump.
The floor height problem, many people think that the floor height of the elevator apartment is relatively low, and the installation of heating and cooling heat pump will cause the room to become depressed, but in fact, the installation of heating and cooling heat pump will not have much impact on the floor height. , The concealment of central air-conditioning can reduce the sense of oppression of the floor height through the reasonable planning of the ceiling, and the floor heating can also be laid by dry floor heating. The floor height is only increased by 3-4 cm, and the user cannot distinguish it with the naked eye.

Heat pump water heater is a new type of water heater. It converts air energy into heat energy through a heat pump to produce hot water. This water heater solves the disadvantage that solar energy cannot be used on rainy days. In addition, this water heater is more efficient compared to gas water heaters and electric water heaters. Environmental protection when you choose this water heater is a very good choice.
What is the main reason why air heat pump water heaters are popular in the market?
What is the workflow of a heat pump water heater?
What do you know about heat pump water heaters that can be used in hotels?
Air Source Water Heater is a new type of low carbon and environmentally friendly water heater. The operating cost of heat pump water heaters is only 1/4 of the cost of electric water heaters, which is very energy-saving and efficient. Originally, as a fourth-generation air water heater, its greatest feature is safety and money-saving! The operating costs of the air water heater are only 1/4 of the electric water heater, 1/6 of the gas water heater, 1/2 of the solar water heater, 2/3 of the fuel water heater and 3/5 of the gas heating system. The device absorbs the heat in the air to heat the cold water, and the cool air released does not pollute the environment and completely eliminates the safety risks such as flammability, explosion, electric shock and gas poisoning of ordinary water heaters.
1. The compressor compresses the low pressure refrigerant flowing back and converts it into a gas with high temperature and high pressure for discharge.
2. The high temperature and high pressure refrigerant gas flows through the copper pipe wrapped around the outside of the water tank, and the heat is passed through the copper pipe into the water tank. The cooled refrigerant becomes liquid under constant pressure and enters the evaporator after passing the expansion valve.
3. As the pressure of the evaporator is suddenly reduced, the liquid refrigerant is quickly evaporated into a gaseous state and absorbs a large amount of heat.
4. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, the energy in the air is absorbed by the evaporator, the air temperature drops quickly, and cold air is released and released.
5. The refrigerant that has absorbed a certain amount of energy is then returned to the compressor and enters the next circuit.
