How does the heating and cooling heat pump work?

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.

What does the operating time of the heating and cooling heat pump have to do?

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?

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.

What is the basic principle of heating and cooling heat pump?

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.

Will the floor height affect the installation of the 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.

Winter has arrived, and people tend to use heat pumps as heating machines. If the heat pump unit can be installed reasonably, the service life and heating capacity of the heat pump will be improved. Let Jnod tell you how to install it, see below:

1. Unit installation location planning

1) The installation requirements of the heat pump main unit are similar to the installation requirements of the outdoor unit of the air conditioner. It can be installed on the roof, balcony, and ground. The air outlet should avoid the windward direction.

2) The distance between the main unit (wind from the side) and the surrounding walls or other obstructions should not be too small. There should be no obstructions within 1 meter of the air outlet, and ensure that the heat exhaustion and suction of the heat exchanger are not hindered.

3) There should be no obstructions within 1 meter of the air inlet of the main unit (top air outlet), and no obstructions within 2 meters of the air outlet to ensure that the heat exhaustion and suction of the heat exchanger of the main unit are not hindered.

When the unit is installed under the eaves or there are horizontal obstacles above the unit, the installation location of the unit must be in a well-ventilated place, otherwise it is easy to short-circuit the air flow, resulting in poor heat dissipation capacity of the unit.

2. Unit installation environment control

1) Try not to place it in direct sunlight.

2) Not on the window sill of the bedroom or near the bedroom.

3) There is enough distance between the air inlet and outlet to facilitate heat dissipation.

4) Places that can withstand more than 2-3 times the weight of the outdoor unit.

5) A place where there is no oily smoke or other corrosive gas.

6) A place that does not affect other factors or the environment.

What is the second stage of the workflow of Swimming Pool Heat Pump?

What should we pay attention to when using Swimming Pool Heat Pump?

What is the first stage of the workflow of Swimming Pool Heat Pump?

In the first step, the indoor hot and humid air in the swimming pool first exchanges heat with the outdoor fresh air through the heat exchanger to become warm and humid air, and then the warm and humid air flows through the evaporator, the temperature drops, and the water vapor condenses into cold water droplets and is separated from the air. Make the air dry and realize the function of air dehumidification; at the same time, the heat energy (latent heat and sensible heat) is released in the process of air cooling, water vapor condensation and cooling are absorbed by the refrigerant.

What is the second stage of the workflow of Swimming Pool Heat Pump?

In the second step, the heat energy absorbed by the refrigerant first (latent heat) heats the pool water through the heat exchanger to realize the pool water heating function: the residual heat (sensible heat) passes through the air condenser to heat the cooled indoor air to realize the air insulation function. In the severely cold winter, when the energy available for the heat pump to extract in the air is too small, and the heat energy recovered by the heat pump is not enough to meet the requirements of the indoor air temperature, the auxiliary air heater is added to supplement the heat energy required for the indoor hot air. The Swimming Pool Heat Pump only needs to provide its own operating power, that is, it runs continuously according to the above working procedures, and achieves a harmonious balance of the three functions of pool water heating, air conditioning and dehumidification with low energy consumption.

What should we pay attention to when using Swimming Pool Heat Pump?

1. When maintaining and cleaning the Swimming Pool Heat Pump, make sure that the Swimming Pool Heat Pump is in a power-off state. In addition, when the heat pump is not in use: the power supply should also be cut off.

2. Do not use gasoline, Tianna water, volatile oil, solvents and other chemicals, or liquid pesticides on the Swimming Pool Heat Pump, otherwise it may cause parts to crack and deform.

3. The area around the Swimming Pool Heat Pump should be kept dry and well ventilated.

4. Regularly clean the air-side heat exchanger to maintain a good heat exchange effect. If the shutdown time is long, the water in the pipeline of the unit should be drained, the power supply should be cut off, and the protective cover should be put on. When it is necessary to use it again, the system must be thoroughly checked before turning it on.

What do you know about heating and cooling heat pumps?

What is the working medium of the heating and cooling heat pump?

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.

What role does the heating and cooling heat pump play?

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.

A heat pump is part of a heating and cooling system. Like an air conditioner, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.

HOW A HEAT PUMP WORKS

A.COOLING MODE

One of the most important things to understand about heat pump operation and the process of transferring heat is that heat energy naturally wants to move to areas with lower temperatures and less pressure. Heat pumps rely on this physical property, putting heat in contact with cooler, lower pressure environments so that the heat can naturally transfer. This is how a heat pump works.

B.HEATING MODE

A Heat pump in heating mode operates just like cooling mode, except that the flow of refrigerant is reversed by the aptly named reversing valve. The flow reversal means that the heating source becomes the outside air (even when outdoor temperatures are low) and the heat energy is released inside the home. The outside coil now has the function of an evaporator, and the indoor coil now has the role of the condenser.

The physics of the process are the same. Heat energy is absorbed in the outdoor unit by cool liquid refrigerant, turning it into cold gas. Pressure is then applied to the cold gas, turning it to hot gas. The hot gas is cooled in the indoor unit by passing air, heating the air and condensing the the gas to warm liquid. The warm liquid is relieved of pressure as it enters the outdoor unit, turning it to cool liquid and renewing the cycle.

Now, more and more families are making the preparation for the Winter, Like installing the heat pump for house heating and hot water.
