Mother’s Day is a holiday honoring motherhood that is observed in different forms throughout the world. In the United States, Mother’s Day 2022 will occur on Sunday, May 8.
Of all the relationships known to humans, there is one that effortlessly outperforms everything else. It's the relationship that a mother and her children share. It's truly valuable because nothing can come close to a mother's unending love, dedication, and devotion to her children. From the time a child is born, the mother fiercely ensures that the young ones feel protected at all times around her and shapes their personality to make them battle all odds in life. Mother's Day is celebrated to recognize the contributions of all mothers.
History and significance
Mother's Day is a special day for all mothers, whose contributions are often overlooked. It's a day to acknowledge the unquantifiable and selfless contributions of every mother in her children's success. It is also a day to thank her for that.
Celebrations
Irrespective of whenever this day is celebrated across the world, people try to make sure that their mother is happy and enjoys her life. They surprise her with gifts or take her out for dinner or even cook for her at home.
A heat pump is part of a heating and cooling system and is installed outside your home. Like an air conditioner, it can cool your home, but it’s also capable of providing heat.
An air-source heat pump works by transferring heat from the outside air to an indoor space. A fan draws in air from outside and transfers it to an evaporator, which is situated in the heat pump. A refrigerant circulates inside the pump, which changes its physical state and evaporates even at low temperatures. The refrigerant steam needs to be raised to a level where it can be used for your heating and hot water, so it’s compressed using a compressor. The heat produced in this process is transferred to the heating and hot water systems in your home.
In cooling mode, a heat pump absorbs heat inside your home and releases it outdoors. In heating mode, the heat pump absorbs heat from the ground or outside air (even cold air) and releases it indoors.

More and more people choose heat pump water heatersbecause air energy is the most energy-efficient, that is, the lowest operating cost, compared to most water heaters that consume electricity and gas.
How does the heat pump water heater achieve the effect of saving energy?
What should we pay attention to when using heat pump water heater?
What are the operational advantages of heat pump water heaters?
When the heat pump water heater is working, the energy QA stored in the ambient medium is absorbed in the evaporator; it consumes a part of the energy itself, that is, the compressor consumes power QB; the heat release QC is carried out in the condenser through the working fluid circulation system, QC=QA+QB, it can be seen that the energy output by the heat pump is the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; therefore, the use of heat pump technology can save a lot of electric energy.
temperature, water consumption
Put the bath water in the heat pump water heater. The most suitable water temperature is 42°C. It can be slightly higher by 1-2°C for middle-aged and elderly people. The water for showering is about 40~50 liters per person. Bathtubs and Jacuzzis are determined by capacity.
How much hot water can be made
In terms of product performance and theory, the heat pump water heater can be cycled back and forth to continuously produce hot water. Under normal temperature, the hot water can be produced per hour as follows (45℃-55℃): It depends on the size of the unit.
The heat pump water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to heat up and pressurize it. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of the electric water heater. Its annual average thermal efficiency ratio is 4 times that of the electric heating, and the energy efficiency is high.
The heat pump water heater overcomes the shortcomings of solar water heaters that rely on sunlight for heating and inconvenient installation. Since the work of the air energy water heater is to exchange heat through the medium, it does not need the electric heating element to be in direct contact with the water, which avoids the danger of electric water heater leakage, and also prevents the gas water heater from the danger of explosion and poisoning, and more effectively controls the gas Air Pollution Caused by Exhaust Gases from Water Heaters.
Guangdong JNOD New Energy Technology Co., LTD. has focused on the field of heat pump water heaters for many years, it commits to providing perfect service for every customer in the world.

In this era of carbon neutrality and carbon peak, people began to understand the concept of environmental protection and began to implement environmental protection policies, such as the use of environmentally friendly and energy-saving products in life, etc. Even the swimming pool water treatment industry has paid more attention to the environmental protection and energy-saving performance of Swimming Pool Heat Pump.
What are the structural features of the Swimming Pool Heat Pump?
Why is Swimming Pool Heat Pump a cost-effective choice?
Why do Swimming Pool Heat Pumps need an anti-condensation system?
1. In line with environmentally sustainable development strategy
Swimming Pool Heat Pump adopts environmentally friendly R407C refrigerant fluorine-free system, which saves energy and reduces emissions, and uses free green energy without pollution.
2. Plasma sterilization, 360 purify air
The Swimming Pool Heat Pump can choose the original plasma sterilization and purification technology, which actively generates a large number of active hydroxide ions, surrounds and adsorbs the bacteria and destroys the protein structure on the surface of the bacteria, so as to achieve the effect of sterilization and purification.
Box structure of Swimming Pool Heat Pump, independent and beautiful
The panel is made of GI galvanized steel material, embedded with polyurethane (PU) fire-proof, sound-insulating and heat-insulating material, and the inside and outside are sprayed with anti-corrosion spray; , The refrigerant compression system accessories are separated from the air duct system of the heat pump independently to avoid corrosion by ammonia-containing air, ensure a longer service life of the heat pump, and facilitate disassembly and maintenance.
①Pressure protection: high pressure protection, low pressure protection, water filling protection;
②Temperature protection: Excessive exhaust temperature protection, compressor overcut protection, hot water temperature protection
③ Power protection: lack/reverse phase protection, compressor overload protection.
① The anti-condensation sensor of Swimming Pool Heat Pump can avoid condensation and condensation on the inner surface of indoor glass windows and walls. When the temperature at the indoor anti-condensation dew point is too low, the anti-condensation sensor installed in the place will fed back the information to the unit control system so that the unit can re-adjust the indoor relative humidity, so that the temperature here is higher than the dew point temperature to prevent condensation.
② If there are parts that are particularly prone to condensation and condensation in the swimming pool space, the Swimming Pool Heat Pump can be equipped with a special anti-condensation and condensation system to ensure that the temperature of the condensation-prone parts of the swimming pool is above the dew point temperature.

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.
