1. Application of plate heat exchanger in heating and air conditioning
Domestic hot water belongs to the utilization of low-temperature thermal energy, and the general temperature is between 25-60 °C. The plate heat exchanger can heat the normal-temperature water to the required temperature through the high-temperature heat source of steam or hot water, and it can also be used between buildings. For cooling and district heating, plate heat exchangers are widely used in air conditioning systems due to their low price, high temperature resistance, corrosion resistance and other advantages.
2. Application of plate heat exchanger in urban central heating
The urban central heating system includes a water-water heat exchange system, a steam-water heat exchange system and a domestic hot water heating system. The plate heat exchanger has the advantages of compact structure, high heat exchange efficiency, simple operation and easy maintenance. Applying it to the urban central heating system can reasonably distribute heat energy and improve the level of heat exchange. Today, the plate heat exchanger has become an indispensable part of the urban central heating system.
3. The effect of plate heat exchanger on ice storage system
When the power load of the ice storage air conditioner is low at night, the electric refrigeration air conditioner is used to make ice and store it in the ice storage device to meet the cooling demand of the next day. This method can reduce the power load during peak hours and the installed capacity of the air conditioning system. , thereby effectively saving energy and costs. Most ice storage systems now use plate heat exchangers, and the effect of plate heat exchangers on reducing grid pressure cannot be underestimated.
4. The pressure effect of plate heat exchanger on high-rise buildings
First, ordinary HVAC systems use water and ethylene glycol as heat transfer media, which tend to generate extremely high static pressures. In HVAC systems in high-rise buildings, plate heat exchangers are used as pressure retarders, The static pressure can be decomposed into lower parts, thereby reducing the pressure of the system on valves, hot and cold water units, etc., effectively saving energy and operating costs.
