Heat Pipe Heat Exchanger Hot Cold

HEAT PIPE HEAT EXCHANGER for Energy Conservation Convert hot to cold and cold to hot. Can be used for air, water, liquid and gases medium Operating temperature 00C to 6000C Unique individual pipes easy to maintain / service Manor heat pipe is a self-contained, passive energy recovery device. A heat pipe can transfer up to 1000 times more thermal energy than copper, the best-known conductor; that too with less than 3.5°C per meter temperature drop. One of the amazing features of the heat pipes is that they have no moving parts and hence require minimum maintenance. They are completely silent and reversible in operation and require no external energy other than the thermal energy they transfer. Heat pipes are ruggedly built and can withstand a lot of abuse. Construction The Manor heat pipe comprises of three elements... a sealed container, a capillary wick structure and a working fluid. The capillary wick structure is integrally fabricated into the interior surface of the container tube. Operating Principle The Manor heat pipe is a super Thermal conductor that transmits thermal energy by evaporation and condensation of the working fluid. The working fluid inside the heat pipe is in equilibrium with its own vapour as the container tube is sealed under vacuum. Thermal energy applied to the external surface of the heat pipe causes the working fluid near the surface to evaporate instantaneously. Vapour thus formed absorbs the latent heat of vaporization and this part of the heat pipe becomes an evaporator region.

Due to the pressure gradients thus created within the heat pipe by the rapid generation of vapour near the surface, the excess vapour is forced to a remote area within the heat pipe having low temperature and pressure. The vapour then travels to the other end of the pipe where thermal energy is removed causing the vapour to condense into liquid again, thereby giving up the latent heat of the condensation. This part of the heat pipe works as the condenser region. The condensed liquid then flows back to the evaporator region to be reused, thus completing a cycle.

Heat is removed from the external surface of the condenser region by conduction, convection or radiation. The heal pipe works continuously in a close-loop condensation/ evaporation cycle and thus, the capillary pumping force is established within the wick structure that returns the working fluid from the condenser region to the evaporator region. The transfer efficiency level of each heat pipe is over 99%.

Manor industrial and commercial heat pipe heat exchanger contains a number of heat pipes. These heat pipes are placed horizontally across the width of the exchanger and pass through a center seal partition to avoid cross contamination. The exchanger is installed across two sideby- side air ducts. The exhaust air and the supply air are discharged in counter flow direction across the exchanger through the ducts to facilitate maximum energy transfer. The heat pipes pick up thermal energy from the exhaust (evaporator region) and transfer it to supply air (condenser region). Manor heat pipe heat exchanger can recover up to, 85% of exhausted thermal energy However, under ideal conditions the thermal efficiency of an economic system ranges between 55 to 70% and saves millions of Kilo Calories year after year. Manor heat pipe heat exchangers as standard are suitable for air-to-air heat recovery fora temperature range of-45°C to + 260°C. With special materials of construction for the tube, the exchanger can be designed to extend the range to425°C to4S(TC

BRINGING ENERGY DOWN TO EARTH: Save Energy. Think Environment. And vice versa. Any company that is energy conscious is also environmentally conscious. Less energy consumed means less waste, fewer emissions and a healthier environment. In short, bringing energy and environment together lowers the cost industry must pay for both.

MANIK ENGINEERS’ development in Fully automatic Gas Purger has led to countless saving in energy, time and money. What are “Non Condensable Gases” in a Refrigeration system? Refrigeration systems accumulate "foul substances". The foul substance gaseous in nature, are commonly referred to as non-condensable gases. Non-condensable gas constituents commonly include air, nitrogen, hydrogen, and hydrocarbons. The term ''non-condensable" means that, these gases will not liquefy at the temperatures and pressures present in condensers consistent with industrial refrigeration systems. For example, ammonia will change phase from gas to liquid if heat is removed while at a temperature of 35°C and a pressure of 12.5 Kg/cm2. At the same pressure, any nitrogen present would have to be cooled to -264°F (-164°C) in order to liquefy. As a result, any nitrogen that may accumulate in a refrigeration system always will remain in a gaseous state.

FIVE WAYS IN WHICH NON-CONDENSABLES ENTER THE SYSTEM:
1. The refrigerant, when delivered, may contain noncondensables up to 15%.
2. For service and maintenance certain parts of the refrigeration plant are frequently opened, causing air to penetrate into the system. Oil changing and recharging with refrigerant have the same effect.
3. Leakage: Systems operating with suction pressure below atmospheric pressure (i.e., working temperatures below -33°C for ammonia system) can have small leaks AUTOMATIC GAS PURGER FOR REFRIGERATION PLANTS (from system piping, valves, vessels valve stem packings, bonnet gaskets, compressor shaft seals, non-welded connections, and control transducers etc.) allowing air to penetrate into the system.
4. Inadequate evacuation before commissioning the refrigeration plant.
5. Decomposition of the refrigerant or the lubricating oil can occur due to catalytic action of the various metals in the installation and due to high discharge temperatures. Ammonia for instance decomposes into nitrogen and hydrogen.

Econet Ambient Cooling System

INTRODUCTION ECONET concept is based on intermittently and efficiently evaporating water on a large area in front of the heat rejection surface of Mini - Split, Rooftop, Air Cooled Chillers, Condensers and Dry Coolers. ECO NET FEATURES Water Spray System Quick change type plastic nozzles connected in series or parallel arrangement in order to provide uniform coverage area for an effective evaporation process. Nozzles are designed to operate with very low pressure and they can operate with normal city mains water pressure 1.5 Barg (21 psig) / (15m ) and above/)

ECONET Non metallic mesh provides an effective coverage area for an efficient evaporation surface with minimal air pressure drop Meshes are fixed in front of the heat rejection surface via spacer bars and / or fixing brackets to suit the unit configuration . Various size sectional mesh panels are either joined together to form a full mesh area or alternatively flexible mesh roll cut to fit to a required size in front of the heat rejection surface. This design provides easy maintenance and replacement for the mesh panels.
