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.

Is there a difference between an air source heat pump water heater and a normal water heater?
What are the environmental protection features of heat pump water heaters?
How does the heat pump water heater work?
Environmental protection, the heat pump water heater realizes that there is hot water whenever you want. Because it does not use electric heating elements for direct heating, compared with electric water heaters, it eliminates the potential safety hazard of electric leakage; compared with gas water heaters, there is no gas leakage, or Safety hazards such as carbon monoxide poisoning, so it has better safety performance. The air energy heat pump is regenerative, and the heating function is automatically activated according to the temperature in the water tank to ensure sufficient supply of hot water for 24 hours, so there is no such problem as the gas water heater that cannot meet the hot water for multiple faucets at the same time, nor will it There is a problem that the capacity of the electric water heater is small, and many people need to wait for a bath. The hot water is ready to use, the water output is large, and the water temperature is stable, meeting all your expectations for hot water. Because its power consumption is only one-fourth of the same amount of electric water heater, which is equivalent to using the same amount of hot water, using an air-energy heat pump, the electricity bill is only one-fourth of that of electric heating. Calculated for a family of 4, the normal consumption of hot water is about 200l/day. Electric water heaters cost about 4 yuan/day for heating, while heat pump water heaters only cost about 1 yuan/day, saving 1,000 yuan a year.
Environmental protection of heat pump water heaters: using clean energy, no waste gas, waste water, waste residue, and no thermal effect on the air. The use of environmentally friendly heat medium, cfc-free, will not cause damage to the atmospheric ozone layer. Uses of heat pump water heaters: heat pump water heaters can be used in hot water systems with a temperature requirement lower than 65°C, such as bathing, sauna, swimming pool, foot bath, beauty salon, agricultural breeding, etc. The heat pump water heater has a high energy efficiency ratio and is more energy-saving.
A heat pump water heater is essentially a heat lifting device. The function of the heat pump is to absorb heat from the surrounding environment and transfer it to the object being heated (a higher temperature object). Its working principle is the same as that of a refrigerator. It works according to the reversed Carnot cycle, the only difference is that the working temperature range is different.

The basic principle of heat pump water heater: It mainly consists of compressor, heat exchanger, axial fan, heat storage water tank, water pump, liquid storage, filter, electronic expansion valve and electronic automatic control. After switching on the power supply, the axial fan starts running, the outside air flows through the evaporator for heat exchange, and the reduced temperature air is expelled from the system by the fan. A kind of low pressure working medium gas is compressed into high temperature and high pressure gas and fed to the capacitor. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and fed to the consumer for use. The working medium is cooled to a liquid and the liquid expands. After the valve is throttled and cooled, it flows back into the evaporator. This cycle works repeatedly, and the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the water tank for heat preservation gradually rises and finally reaches about 55°C, which is just suitable for people to take a bath.
Heat pump water heaters are a new thing on the market, and consumer awareness of this is still very low. There are many people who think that it is impossible to get three parts heat with one part heat, and the same applies to other products related to the application of heat recovery technology, although the popularity of heat pump air conditioners was very high.
People's understanding is limited only to the fact that air conditioning is a large electricity consumer, but they do not know that it is more energy-saving than the coal-fired ball furnace. As some larger shopping malls have not yet sold air-powered water heaters, consumer awareness of air-powered water heaters is still very low.
In order to meet these growing requirements, Guangdong JNOD New Energy Technology Co., LTD. has various heat pump water heaters, which allow to increase the products and make them more effective, reliable and consistent.
The Swimming Pool Heat Pump unit dehumidifies the indoor air while keeping the indoor air at a constant temperature. In order to save energy, the air heat is fully recycled during the operation of the equipment, and the recovered heat is used to heat the pool air or pool water through the regeneration system to ensure that the indoor air is at a constant temperature. The condensed water produced by de-temperature can be directly discharged outdoors or recycled into the swimming pool to supplement the pool water.

How does the Heating and Cooling Heat Pump perform cooling and heating respectively?
What is the principle of Heating and Cooling Heat Pump?
Why is Heating and Cooling Heat Pump so practical?
When the air conditioner cools down in summer, the Heating and Cooling Heat Pump operates according to the cooling condition, and the high-pressure steam discharged from the compressor enters the condenser through the reversing valve (also known as the four-way valve); when heating in winter, the reversing valve Turn to the working position of the heat pump, so the high-pressure refrigerant vapor discharged from the compressor flows into the indoor evaporator (used as a condenser) after passing through the reversing valve, and the latent heat released when the refrigerant vapor condenses heats the indoor air to achieve indoor heating purposes. The condensed liquid refrigerant flows in the reverse direction through the throttling device into the condenser (used as an evaporator), absorbs external heat and evaporates, and the evaporated steam is sucked by the compressor after passing through the reversing valve to complete the heating cycle. In this way, the Heating and Cooling Heat Pump "pumps" the heat from the outside air (or circulating water) into the room with a higher temperature, so it is called a "heat pump"
When the air conditioner cools down in summer, it operates according to the refrigeration condition. The high-pressure steam discharged from the compressor by the Heating and Cooling Heat Pump enters the condenser through the reversing valve (also known as the four-way valve), and the refrigerant vapor is condensed into liquid. The flow device enters the evaporator, absorbs heat in the evaporator, cools the indoor air, and the evaporated refrigerant vapor is sucked by the compressor after passing through the reversing valve, and this cycle is repeated to realize the refrigeration cycle.
Heating and Cooling Heat Pump can operate normally between -27℃-48℃, and some low-temperature air-energy heat pumps are also capable of -35℃ ambient temperature, and still maintain normal operation. In our environment, a It can be used all-weather all year round, and will not be affected too much by rainy, windy and snowy weather, nor will it be affected by low temperature at night. However, solar heating equipment is greatly affected by environmental factors. In the case of insufficient light, it is difficult to achieve the effect of indoor heating, especially in areas with low ambient temperature in winter.

The Heating and Cooling Heat Pump is driven by an electric motor, uses the heat in the air as a low-temperature heat source, exchanges heat through the air conditioner condenser or evaporator, and then passes through the circulation system to extract or release heat energy, and use the unit circulation system to transfer the energy to the building. It can meet the needs of users for domestic hot water, floor heating or air conditioning.
What is the cycle between the Heating and Cooling Heat Pump and the natural environment?
What is the principle of Heating and Cooling Heat Pump?
Does the Heating and Cooling Heat Pump make noise?
The compressor outlet of the Heating and Cooling Heat Pump is high-temperature and high-pressure gas, which is transformed into a high-pressure and low-temperature vapor-liquid mixture through the heat exchange of the condenser. The low-temperature gas enters the evaporator to evaporate and absorb heat, and absorb the low-grade heat energy from the outside world (which can be rivers, lakes, groundwater, underground soil layers, air, etc., which we call water source, ground source, and air source heat pump), and finally the evaporator comes out. The low pressure gas enters the compressor to complete the cycle.
Heating and Cooling Heat Pump is an evolved product of air conditioners. An electromagnetic four-way valve (also known as a reversing valve) is installed in the refrigeration system. Through the switching direction of the four-way valve, the flow direction of the refrigerant is changed, and the air conditioner can hot. The high-temperature and high-pressure vapor-like refrigerant discharged from the compressor flows to the condenser in the heat preservation water tank, transfers heat to the tap water passing through the water tank, and then throttles and reduces the pressure through the expansion valve, and evaporates and absorbs heat in the evaporator of the main outdoor heat pump group. Use the working fluid to absorb the heat in the outdoor air. The Heating and Cooling Heat Pump absorbs the heat in the outdoor air and transfers it to the tap water in the insulated water tank. It is more energy-saving, fast and safe than simply heating with an electric heater, and the outdoor thermal energy potential is infinite.
Noise problem, almost all of today's Heating and Cooling Heat Pumps use full frequency conversion technology, indoor unit frequency conversion, heat pump host frequency conversion, fan frequency conversion, etc. The noise value of the heat pump host is below 45 decibels, and the indoor noise is still below 20 decibels. Neither users nor neighbors will be affected.
