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.

The inverter technology is considered a perfect solution when it comes to energy-efficiency and economical operation. In an inverter model from a heat pump inverter manufacturer, the cooling and heating are automated in an energy-efficient and seamless manner whereas earlier technologies used to consume a lot of electricity irrespective of the required usage.This will be good to cut-off your electricity bill.
The compressor motor used by DC inverter heat pump manufacturer does not turn on and off all the time but keeps working at low power. This kind of machine makes the operation more quite.
Unlike non-inverters, they don't automatically turn on and off every time they reach a certain temperature; instead, they just cruise along maintaining and regulating the temperature constantly.
The technology and hardware employed in DC inverter model by DC inverter heat pump supplier not only makes the cooling and heating effect more efficient, but also makes the unit last longer. Contrary to the operation of a non-inverter unit, the inverter uses less power and as a result, they work less, meaning that they are less prone to wear and tear.
The DC inverter heat pump is able to cool and heat your room faster than its non-inverter counterpart. This is due to the fact that an inverter heat pump unit operates on a variable speed compressor rather than at a fixed speed one. This process ensures rapid air conditioning effects via faster variable speed allowing the compressor to run at full power only when required while constantly regulating the temperature as per end user's desire.
A smart DC Inverter heat pump will provide you complete control over energy consumption and usage through your PC and portable smart devices. Moreover, it will give you complete insights about all technical metrics such as watts, voltages, current and units consumed. A smart heat pump also lets the user schedule the heat pump to automatically turn itself on or off. Operations of a heat pump are more flexible and centralized when it is smart.

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.

What is a direct heat pump water heater?
What are the characteristics of direct heat pump water heaters?
What is the main structure of the direct heat pump water heater?
The direct heat pump water heater is also known as the fast or fast heat pump water heater. The basic characteristics of the direct heat pump water heater are: cold water and superheated water, as long as the tap is turned on, the energy source will continuously supply hot water within a few seconds. Turn off the faucet when you don't need hot water.
According to different heating forms, direct heat pump electric water heaters can be divided into the following three types:
①, bare electric wire heating electric water heater;
②, electric film heating electric water heater;
③, electric heating tube heating electric water heater.
The heater of the direct heat pump water heateris set in a tank frame, which cannot withstand too high water pressure. At the same time, the left and right poles of the tank frame and the two poles introduced by the heating wire will be affected by water pressure for a long time. be damaged. Therefore, direct heating heat pump water heaters cannot be made into the post-system, but are all made into the front-system. In addition, in order to ensure the safe use of direct-heat heat pump water heaters and no dry burning occurs, a pressure sensing activation switch with water flow as a signal is installed at the cold water inlet, and the pressure sensing activation switch diaphragm can withstand the pressure. It is limited and cannot withstand pressure for a long time, so direct heat pump water heaters are generally made into the former system.
A typical direct heat pump water heater is mainly composed of a heating tank plate, a pressure sensor, a power regulator, a water volume adjustment faucet, a water inlet pipe and a water outlet pipe component, among which the heating tank plate is the key component of the direct heat pump water heater. It consists of a groove weight, a sealing ring, a cover and an electric heating element, and the electric heating element is located in the groove of the groove plate.
The direct heat pump water heater works by direct conduction heating. Since the electric heating element is placed in the groove of the groove plate, when the cold water flows through the groove, it can directly flow through the surface of the heating element to be heated. And because the water tank is like a snake, the cold water flowing into the water inlet is gradually heated, and hot water with a higher temperature can be obtained at the water outlet.

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.
