泳池、SPA、桑拿及溫室的高效供熱製冷對策
The use of plate heat exchangers for heating pools, spas & saunas, and greenhouses has become common practice, mainly due to the thermodynamic advantages and low cost compared to shell-and-tube technology. A plate heat exchanger can utilize heat from various sources, including district heating, solar-heated water circuit, or geothermal groundwater. It can also use chilled water to remove heat when the application in question must be cooled.

Trends in the industry
Swimming pool facilities with spas and saunas are used for both fitness and recreation. In recent years there has been an influx in demand for these types of spaces with growing tourism and health consciousness. Greenhouse technology for food production has also become increasingly popular as climate change adversely affects crops. Both industries are looking to become more sustainable by making the most out of available heat, regardless of the source. Low-carbon heating and cooling is also a crucial priority as the global energy system moves away from fossil fuels as a source of energy. The challenge is making these changes happen, without compromising on performance.
By choosing Alfa Laval, you won’t have to compromise. Our heat exchangers allow a close temperature approach for maximum heat recovery while maintaining a steady temperature in your pool, spa, sauna, or greenhouse. As a company, we are dedicated to enabling the clean energy transition, reducing the carbon footprint of our value chain, and enabling your process to be as energy efficient as possible.
Swimming pool
Pools require heating to the optimum set temperature, comfortable for recreation and fitness. The heat source has traditionally been a hot water boiler but can also be a solar-heated water-circuit, district heating or geothermal groundwater. A heat exchanger should separate the primary heating loop from the secondary, which will contain the pool water. This is both for safety and hygiene purposes. The heat exchanger should be placed before chlorination to reduce corrosion and equipment damage. Alfa Laval caters to pools of various sizes and heat demands with customizable gasketed plate heat exchangers.
In tropical climates, it may be necessary to cool the water temperature of a swimming pool. This can be achieved using chilled water as the other medium.

Spas & Saunas
Spas and saunas are popular recreational activities that require heating and maintenance of a comfortable set temperature. Regardless of the dimension of your facility, Alfa Laval’s heat exchangers can be tailored to suit your application. The heat source can be geothermal groundwater, or a solar-heated water circuit, among others. A heat exchanger that separates the primary and secondary loops will transfer the thermal energy to the spa/sauna water. The high flow rate of fluid through the heat exchanger enables self-cleaning, reducing the chance of fouling and sediment build-up, allowing your application to run for longer, with minimum downtime.

Greenhouses
Whether growing vegetables or flowers, a greenhouse requires the right temperature and humidity for optimum yield. The energy source in the case of heating will often be geothermal groundwater. Heat is transferred from the energy source to the water that is circulated in mild steel piping installed along the soil bed using an Alfa Laval heat exchanger. Depending on the composition of the geothermal water, plate heat exchangers with Titanium plates could be required to minimize the risk of corrosion and reduce sediment build-up and fouling. Low-temperature heat is sufficient, which is efficiently recovered with a gasketed plate heat exchanger from Alfa Laval.
In some climates, the air in the greenhouse may need to be cooled. This is achieved using chilled water as the other medium.
