In the previous article, we talked about what air source heat pumps are and their advantages. This article mainly discusses the types of air source heat pumps and how to choose a suitable household air source heat pump.
Air source heat pump types
According to the size of the unit capacity, it is divided into household small units, medium units, large units, etc.
According to the form of unit combination, it can be divided into integral units (units with one or several compressors sharing one water side heat exchanger are called integral units) and modular units (units composed of several independent modules are called modular units).
1. Air source heat pump underfloor heating
Air source heat pump air energy (source) heat pump floor heating utilizes low-grade heat energy in the air to be compressed by a compressor and converted into high-temperature heat energy. The water temperature is heated to no more than 60 ℃ (usually 35-50 ℃) and circulated as a heat medium in a dedicated pipeline to heat the ground decoration layer. The ground is heated by radiation and convection heat transfer from the ground, and the heat rises from the building surface to evenly distribute the temperature of the entire indoor space without a sense of hot air, which is conducive to maintaining moisture in the environment and improving human comfort.
Transporting heat from the air to indoor heating saves 75% of electricity compared to electric underfloor heating. It provides 24/7 heating and is easy to install. It is buried underground and is space saving, and can be paired with different decoration styles. It can also meet various needs such as household and commercial use.
2. Air source heat pump central air conditioning
Air energy (source) heat pump central air conditioning obtains a large amount of heat from the air for free from the outside, and then transfers the heat to the indoor environment through electrical energy, achieving an energy-saving effect of generating more than three parts of heat from one part of electricity. It has high efficiency, no pollutant emissions, and does not affect the atmospheric environment. It provides a good choice for owners and developers to choose convenient, energy-saving, and efficient central air conditioning.
3. Air source heat pump water heater
Air source heat pump water heater is a type of water heater that is loaded with an air source heat pump to absorb low-temperature heat from the air. After being compressed by a compressor, it is converted into high-temperature heat energy to heat the water temperature. Traditional electric water heaters and gas water heaters obtain heat energy by consuming gas and electricity, while air energy (source) water heaters achieve the purpose of heating water by absorbing heat from the air. Under the same electrical energy consumption, they can absorb about three times the amount of heat energy to heat water. They also overcome the disadvantages of solar water heaters being unusable on cloudy and rainy days and inconvenient installation, and have many advantages such as high safety, high energy efficiency, long service life, and no emission of toxic and harmful gases.
Air source heat pump water heaters have the characteristics of high efficiency and energy conservation. Under the premise of producing the same amount of hot water, the consumption cost of air source water heaters is only 1/4 of that of electric water heaters, and even higher than the energy efficiency of electric assisted solar water heaters.
