Complaint
Product name | Plate heat exchanger, rekuperator |
Brand | Holtop |
Material | Aluminum foils |
Function | Used in comfortable air conditioning ventilation system and technical air conditioning ventilation system. Supply air and exhaust air totally separated, heat recovery in winter and cold recovery in Summer |
Type | Sensible heat exchanger |
Working principle of Cross-counter flow plate heat exchangers (air-to-air)
Two neighbor aluminum foils form a channel for fresh or exhaust air stream. Heat is transferred when the partial air streams flow crossly and partial air streams flow counter through the channels, and fresh air and exhaust air is totally separated
Main features
1.Sensible heat recovery
2.Total separation of fresh air & exhaust air streams
3.Heat recovery efficiency up to 80%
4. 2-side press shaping
5.Double folded edge
6.Completely joint sealing.
7.Resistance of pressure difference up to 2500Pa
8.Under pressure of 700Pa, air leakage less than 0.6%
Material type
B series (standard type)
Heat exchanger is made of pure aluminum foils, with galvanized end cover and aluminium alloy wrap angle. Max.air temperature 100°C, it is suitable for most of the occasion.
G series (high temperature type)
Heat exchanger is made of pure aluminum foils, with galvanized end cover and aluminium alloy wrap angle. Sealing material is special and allow the Max. air temperature to be 200°C, it is suitable for special high temperature occasion.
F series ( Anti-corrosion type)
Heat exchanger is made of pure aluminum foils cover by special anti-corrosion material, with galvanized end cover and aluminium alloy wrap angle., it is suitable for the corrosive gas occasion.
Aluminum foils thickness range from 0.12 to 0.18mm because of the different specification heat exchanger.
Heat exchanger size and air volume
THE MAJOR IMPACT OF FACTORS
Heat exchange coefficient
According to research, heat exchange rate is based on the heat exchange coefficient, larger coefficient means higher
heat exchange rate. Holtop use the special pure aluminum foils to produce heat exchanger, heat exchange rate is effectively improved.
Heat exchange area
Heat exchange capacity is relevant to the heat exchange area. By changing the plate structure, increase heat exchange area, heat exchange efficiency is also increased. In order to increase the heat exchange area, Holtop heat exchanger has grooves in all the plates.
Plate distance
Small plate distance can increase heat exchange efficiency, but resistance also increased. Large plate distance means
less resistance but efficiency is low. Only choose the suitable plate distance can have ideal heat exchange efficiency.
Turbulent flow
Because the special plate structure of Holtop heat exchanger, when airstream enter the heat exchanger will become turbulent so heat exchange efficiency increased
