A couple from a TTD Session

One of the pro motocross riders I shoot got married, and his lovely wife was game to have a little fun.

How fun that must have been!

Gary Peterson Photography

It was...
This should go in sports, but here is the husband....

THAT is very cool! What fun..nice shots

marikris

Yeah, you don't see that everyday! Way cool and a lovely bride. Specially love that shot of her on the bottom right corner.

How on earth did she keep the dress out of the chain???

Or the spokes????

Lol...

Very carefully....sitting on lots of dress....although I did notice that when we were finished, a bit of the touling from underneath had turned a bit brown...toasting on the muffler!

Very fun...I'd love to see a closer crop of her with those goggles on, along with the train~

angevin1

Nevermind...I went to the gallery and looked...she makes that bike look good!:D

Hmmm...

The two main heat pumptypes

Discuss with Professional heat pump manufacturer:China PalmAlmost all heat pumps currently in operation are either based on a vapour compression, or on an absorption cycle. These two principles will be briefly discussed in the following two sections. Theoretically, heat pumping can be achieved by many more thermodynamic cycles and processes. These include Stirling and Vuilleumier cycles, single-phase cycles (e.g. with air, CO2 or noble gases), solid-vapour sorption systems, hybrid systems (notably combining the vapour compression and absorption cycle) and electromagnetic and acoustic processes. Some of these are entering the market or have reached technical maturity, and could become significant in the future.Vapour compressionThe great majority of heat pumps work on the principle of the vapour compression cycle. The main components in such a heat pump system are the compressor, the expansion valve and two heat exchangers referred to as evaporator and condenser. The components are connected to form a closed circuit, as shown in Figure 1. A volatile liquid, known as the working fluid or refrigerant, circulates through the four components.In the evaporator the temperature of the liquid working fluid is kept lower than the temperature of the heat source, causing heat to flow from the heat source to the liquid, and the working fluid evaporates. Vapour from the evaporator is compressed to a higher pressure and temperature. The hot vapour then enters the condenser, where it condenses and gives off useful heat. Finally, the high-pressure working fluid is expanded to the evaporator pressure and temperature in the expansion valve. The working fluid is returned to its original state and once again enters the evaporator. The compressor is usually driven by an electric motor and sometimes by a combustion engine.

• An electric motor drives the compressor (see Figure 1) with very low energy losses. The overall energy efficiency of the heat pump strongly depends on the efficiency by which the electricity is generated. This is discussed in the section on Heat pump performance.
  
• When the compressor is driven by a gas or diesel engine (see Figure 2), heat from the cooling water and exhaust gas is used in addition to the condenser heat.
• Industrial vapour compression type heat pumps often use the process fluid itself as working fluid in an open cycle. These heat pumps are generally referred to as mechanical vapour recompressors, or MVRs; refer to the section on Heat pumps in industry.

Absorption heat pumps for space conditioning are often gas-fired, while industrial installations are usually driven by high-pressure steam or waste heat.Absorption systems utilise the ability of liquids or salts to absorb the vapour of the working fluid. The most common working pairs for absorption systems are:

• water (working fluid) and lithium bromide (absorbent); and
• ammonia (working fluid) and water (absorbent).

For heat transformers, which through the same absorption processes can upgrade waste heat without requiring an external heat source, refer to the section on Heat pumps in industry.
