Energy saving scheme for heat recovery of central air conditioning system

Système d'économie d'énergie pour la récupération de chaleur du système de climatisation central

Pour les systèmes de climatisation centralisée, nous pouvons utiliser des échangeurs de chaleur à haut rendement pour des projets de rénovation écoénergétiques. Nous pouvons également choisir des échangeurs de chaleur à plaques ou à microcanaux offrant un transfert thermique efficace et une faible résistance aux fluides. Nos échangeurs offrent une surface de transfert thermique plus importante et une performance thermique plus efficace, ce qui permet de réduire la consommation d'énergie à conditions de transfert thermique identiques. L'installation d'un récupérateur de chaleur dans le système de climatisation centralisée permet de récupérer et de réutiliser la chaleur émise. Il est également possible de l'associer à une pompe à chaleur, un moyen efficace de transférer l'énergie thermique d'une source de chaleur basse température vers une source de chaleur haute température en consommant peu d'électricité ou de combustible. L'utilisation de la pompe à chaleur dans les systèmes de climatisation centralisée permet d'améliorer le coefficient de performance (COP) du système et de réduire la consommation d'énergie.

Exhaust gas heat exchanger for heat pump drying

Combinaison libre d'échangeurs de chaleur pour unités de climatisation

Modular air conditioning units are an efficient and flexible central air conditioning solution that can be freely combined according to the actual needs of buildings, meeting different cooling or heating requirements by increasing or decreasing the number of units. Each unit is connected to each other through a return pipe and a supply pipe, forming a modular combination of a main return pipe and a main supply pipe.
We use plate heat exchangers, which have a heat transfer coefficient 3-5 times higher than tube heat exchangers under the same pressure loss. They occupy one-third of the space of tube heat exchangers and can achieve a heat recovery rate of over 90%.
Our air-cooled heat pump air conditioning unit adopts a compression refrigeration cycle, which is a dual-purpose air conditioning cooling and heating source unit. During summer cooling, outdoor air is used for heat dissipation (air cooling), while during winter heating, heat is extracted from outdoor air (air source).

Plate heat exchanger for drying linen in hotels and laundry industry

Échangeur de chaleur à plaques pour le séchage du linge dans les hôtels et les blanchisseries

Application principle:
During the washing and drying process of linen, steam or hot water enters one side of the plate heat exchanger as a high-temperature fluid, while the air to be heated (for drying) enters the other side as a low-temperature fluid. Through a plate heat exchanger, the high-temperature fluid transfers heat to the low-temperature fluid, causing the air temperature to rise and achieving the purpose of preheating.
Plate heat exchangers have good thermal conductivity and can effectively transfer the heat of steam to linen, improving thermal efficiency. This means that the drying process of linen can be completed faster or energy consumption can be reduced with the same energy consumption.
Structural design: The plate heat exchanger is composed of multiple thin metal plates that form sealed channels between them. Metal plates are usually made of materials with good thermal conductivity, such as aluminum foil, copper foil, or stainless steel foil.
Energy saving and environmental protection: By recycling and reusing heat energy, plate heat exchangers can reduce steam consumption, lower energy consumption, and protect the environment. This is particularly important for places such as hotels, guesthouses, hospitals, and the laundry industry that require a large amount of washing and drying of linen.
The application principle of the plate heat exchange core of the linen washing and drying heat exchanger is based on the basic principles of heat conduction and convection, and efficient heat exchange is achieved through reasonable structural design and material selection.
