Home technology expert Ross Tretheway discusses the new age of homeheat pumpsin a Future House feature. Ross takes us through the four different types: water to water, water to air, air to air, and air to water. He details how those systems work and how they pull warmth from the ground. Ross talks to his father, plumbing and heating expert Richard Tretheway, about how heat pumps have evolved.
How Heat Pumps Work
热泵通过发现和移出建筑物来工作和移出建筑物。夏季，热泵将在家里吸收热量，并让其在外面消散，从而使空调系统更有效地工作。bob体育app苹果下载HomeHome
In the winter, a heat pump can scavenge heat from the outdoors (even in temperatures as low as zero degrees) and pump it into the home for comfort. The only requirement? Enough electricity to run the compressors.
的re are Two Sides to the Story
Heat pumps have two sides: the source side and the load side:
- 源侧是泵从那里收集热量的地方。在夏天，房屋的内部将是源头。HomeHome在冬季，系统的室外侧是源侧。
- 的load side is where the heat is being delivered to. The heat pump removes the heat in the summer and dumps it outside, making the outdoors the load side. In the winter, the heat pump sources heat from outside and supplies the home, making the house the load side.
Geothermal Heat
许多热泵系统需要地热热。这是被困在地球表面的热量，它全年保持温度一致。这些系统需要向下钻入地球并运行管道系统的水系统。然后，水通过地面并回到系统以进行加热时吸收热量。
这些系统通常很昂贵，并且在120度左右（锅炉可能会更高）最大化。但是，它们比其他一些系统更有效，使bob体育app苹果下载其成为绝佳的选择。
Different Types of Heat Pumps
Heat pumps are becoming more and more advanced, but there are four basic types: water to water, water to air, air to air, and air to water.
水到水
这种热泵需要地热钻井，这意味着要在地球上钻入热量。水在地面下方行进，向上抬起，然后通过热交换器行进。在热交换器中，源水加热负载水。然后，负载侧水通过加热系统，就像迫使热水系统一样。
Water to Air
Water to air systems require geothermal drilling to source the heat in the earth’s surface. Then, the hot water runs through a coil in a duct. When air blows across that coil, it heats up, just as it would with a furnace.
Air to Air
In an air to air system, the heat pump sources heat from the air on the load side, which is then transferred to a refrigerant. This refrigerant then travels through a coil inside the ductwork, where load side air blows across it, similar to a furnace. These are the most common heat pumps.
空气到水
An air to water system sources heat from the air on the source side and transfers it to a refrigerant. This refrigerant then cycles through a heat exchanger where it can heat the load side water to be pumped through the house.
Once in the house, this water can serve several purposes. It can be pumped to a zone manifold for hydronic heat, cycled through a heat exchanger for domestic hot water, or even pumped through a coil to supply a ducted system. In the summer, this system can remove heat from the home, cool the refrigerant, and supply the home with cooling.
的re are a ton of advantages to this system over the others. First, no drilling is required. Second, you get the efficiency of hydronics. In some cases, homeowners relying on older heating systems can expect to save thousands of dollars each year on heating costs, as well.
Resources
Ross explored four different types of heat pump systems: water-to-air, water-to-water, air-to-air, and air-to-water. These heat pumps can usually be sourced through a local HVAC technician or sales representative.
