Microcapsule phase change material for air conditioning HVAC systems

Product Overview

Description

Application of phase change materials in building HVAC

 

 

 

Microcapsule phase change materials can be used for indoor floors, walls, ceilings, phase change material glass, and the like. The phase change material exchanges heat with the indoor environment to maintain a comfortable temperature in the room.
Product line: Honeycomb sheet
Microcapsule powder

 

 

purpose:

1. Energy-saving: use nighttime low-cost electricity to store energy and release refrigeration when needed during the day;

2. Space saving: reduce the volume of the ice storage tank;

3. Constant temperature: fluctuation of the surface temperature, always constant temperature.

 

 

application:

Residential, small and medium-sized buildings, hospitals, banks, airports, etc.

Several forms of industrial constant temperature and humidity machine air conditioning system

Energy saving calculation example:

 

The example of a medium-sized heat storage tank (35m3, 10 tons) is calculated:

 

Heat storage capacity of 1MWh large-scale heat storage tank (35m3, 10 tons of ice)

 

Ice storage heat = 320kj/kg. Microcapsule heat storage = 200kj/kg*0.8 (actual volume) = 160kj/kg

 

 

 

Traditional ice heat storage tank

 

Where 35 tons of water can produce 10 tons of ice (the ice making rate is about 30%):

 

10*103kg*320kj/kg=320GJ (heat storage)

 

 

 

Ice + phase change microcapsule heat storage tank

 

In order to achieve the above-mentioned ice heat storage capacity (320GJ), 12 tons of phase change microcapsules are solidified (6 ° C), and then 4 tons of water is frozen (-19 ° C). Under these conditions, the heat storage of the two is:

 

 

Ice: 4*103kg*320kj/kg=128GJ

 

Phase change microcapsule: 12*103kg*160kj/kg=1.92GJ

 

 

Compared with the original ice storage method, the power consumption ratio is: (1.28 + 1.92 * 1/2) / 3.2 = 0.7, that is, energy saving 30%.
