Results for the case study

In this section, effects of the drying air temperature and the mass flow rate of drying air on the system performance were discussed. Specific heats, enthalpies, and entropies of the broccoli florets were calculated from Eqs. (15.2), (15.10), and (15.11-15.12), respectively. The properties of the inlet and outlet air were calculated from the computer aided thermodynamic tables. The reference (dead state) temperature for exergy analyses was taken to be 23oC. Exergy analyses of single-layer drying process of broccoli florets in a heat pump conveyor dryer were performed by using the data obtained from the experiments (Table 15.2).

Weaknesses of present sliding theory

Frictional drag may also occur in areas where ice becomes temporarily frozen to the bed. Robin (1976) proposed two mechanisms for forming such cold patches. In the first, which he termed the heat pump effect (Figure 7.6a), water that is formed in the zone of high pressure

Environmental controls and glacier behaviour an overview

The thermal regime is also partly determined by geological conditions, and in particular subglacial geothermal heat flux. The variability of geothermal heating can lead to temporally variable effects, such as massive subglacial melting beneath Vatnajokull in Iceland associated with volcanic activity, leading to intermittent jokulhlaups (e.g. Gudmundsson et al., 1997), or spatially variable effects, such as the initiation of rapid flow within the Greenland Ice Sheet over areas of thin crust with high geothermal heat flux rates (Fahnestock etal., 2001).

Ecosystem Processes At Scales Of Whole Reefs And Zones

Subsequent work, which has embraced a greater variety of reef types, notably those on continental shelves, has modified some aspects of this view of reef function (Pomeroy el al. 1974 Hatcher 1988 D'Elia and Wiebe 1990 Rougherie and Wauthy 1993). Rougherie and Wauthy (1993) proposed that atolls receive a major input of nutrient-rich water from the deep ocean. Geothermal heating reduces the density of deep, nutrient-rich water, causing it to percolate to the surface of the atoll, where the nutrients are incorporated into microbial systems, plankton and higher food chains. This hypothesis provides a mechanism for sequestering a major exogenous supply of nutrients.

Table 41 Alternatives to Fossil Fuels for Heating and Cooling

Ground-source heat pump Geothermal energy is used for everything from space heating and cooling to warming greenhouses and melting snow on roads and bridges. In France, Iceland, New Zealand, the Philippines, Turkey, the United States, and other countries with high-temperature resources, geothermal heat is used for electricity generation, district heat, and industrial processes like pulp and paper production. Ground-source heat pumps, which can be used virtually anywhere, use the stored solar energy of Earth or well water as a heat sink in summer and heat source in winter. The United States has the world's largest heat pump market, with up to 60,000 systems installed annually.40 According to the IEA, solar water heating, biomass for industrial and domestic heating, deep geothermal heat and shallow geothermal heat pumps are amongst the lowest cost options for reducing both CO2 emissions and fossil fuel dependency. In many circumstances these technologies offer net savings as compared to...

The North Atlantic Current

Some scientists have argued that global warming might have an effect on the North Atlantic Current. As Arctic glaciers melt, freshwater may be dumped into the current. As discussed earlier, both temperature and salt-water content have an impact on currents a giant dump of cold, freshwater could therefore have an effect on how a current flows. The worry is that the current could rapidly collapse, turning off the huge heat pump and altering the climate over much of the Northern Hemisphere.19 Some scientists have suggested that the result could be a new ice age.

Case Study Broccoli Drying

Latest Conveyor Drying Systems

Broccoli florets were dried in a heat pump conveyor dryer designed and constructed in the Department of Mechanical Engineering, Faculty of Engineering, Ege University, Izmir, Turkey, shown schematically in Fig. 15.1. Drying system consists of two main parts (i) heat pump and (ii) drying chamber. The air was heated by heat pump system that included a scroll compressor, two condenser (an internal and an external ones), expansion valve, evaporator, and a heat recovery unit and air temperature was controlled by a control unit. R407C was used as refrigerant in heat pump system. The drying air velocity was regulated by a fan and fan speed control unit and drying air was recycled. Drying compartment dimensions were 3 m x 1 m x 1 m and drying material was moved by a conveyor band system worked by a motor. Fig. 15.1 Schematic illustration of heat pump conveyor dryer system.

Canadian Association for Renewable Energies

The association maintained extensive websites, featuring information on the theory and application of renewable energy technologies, particularly those related to heat-pump applications. They maintained their online news feed until December 2006. The association is closely tied to the Earth Energy Society of Canada, formerly the Canadian Earth Energy Association, which was formed in 1989 to promote ground source geothermal heat pumps. It administered a 20 million program during the 1990s devoted to installing ground heat-pump systems. The Green Heat Partnership was formed in 2001 to encourage the adoption of space and water heating applications that use renewable energy technologies. Partners include the Earth Energy Society of Canada, the Canadian Solar Industries Association, the Canadian Biomass Association, and other private partners. Technologies being showcased by the initiative include heat pumps, solar thermal water heaters, solar thermal air heaters, and biomass combustors....

Towards the positive energy building

Energy conservation can be ensured by using better performing heating devices such as high efficiency boilers (condensing boilers), heat pumps or cogeneration. Cogeneration and heat pumps enable a better use of electricity. In a fossil fuel power plant, electricity is produced from a heat source with a yield which, in most cases, does not exceed 35-40 . The remaining energy is released and transmitted to the refrigeration air or water. In the case of cogeneration, the heat released is used for heating residential buildings or industrial installations. A heat pump operates according to a different principle. It operates in a way similar to a refrigeration device. By withdrawing heat from an external medium (water or air), it supplies a quantity of heat much larger than the electrical energy consumed. The ratio of the quantity of heat thus delivered over the consumed electrical energy (coefficient of performance or COP) is frequently around 3. Cogeneration is mainly applied in industry...

Models of Late Quaternary climate and icesheet evolution

(2) During a pre-glacial episode following an interglacial, the Nordic heat pump is reduced in strength or stopped, while the Antarctic circulation cell is enhanced. (3) During a full glacial, the open ocean heat pump operates at a maximum, while the Antarctic cell is stronger than during an interglacial. (4) During d glaciation, the Nordic cell is restabilized, while the open ocean heat pump is stronger than during interglacial periods. This model demonstrates how a change in one oceanic circulation component immediately affects the entire system. Reduced terrestrial radiation receipts as a result of Milankovitch forcing causes glacial ice cover and sea ice to expand. During this stage, the Nordic heat pump becomes gradually reduced and flow is concentrated in the open ocean. Evaporation from the ocean surface and lowering of the temperatures will occur simultaneously with a shift in the position of the westerly winds and more enhanced ocean circulation in lower latitude oceans. In...

Subnational action Then and now

Many other sub-national governments around the world have taken innovative steps to reduce greenhouse gas emissions. Colleagues in Canada are amongst those leading the way. British Columbia, for example, a mountainous province on the west coast of Canada, is the first North American jurisdiction to introduce a revenue neutral carbon tax. All carbon tax revenue will be recycled to British Columbians through tax reductions. British Columbia also requires that all new electricity projects have zero net GHG emissions and is the first state in North America to legislate the requirement for the public sector to be carbon neutral by 2010. Manitoba, a prairie province in the heart of Canada, has been harnessing geothermal technology. As a result of innovative incentives and loan programmes, Manitoba is the North American leader in ground source heat pump installations, quadrupling sales in recent years.

Ohio state university

Ohio State University has initiated the development of two green buildings on campus. The first building is the Nationwide and Ohio Farm Bureau 4-H Center. It opened in early 2008. This building includes carbon-reducing features, such as geothermal heating, the use of recycled rainwater, and environmentally-sound building materials. The student union, known as the Ohio Union, is under construction. The new Ohio Union will feature a location that discourages driving and encourages public transportation and walking, energy-saving lighting, and the reuse of existing union building materials. This building will open in 2010.

Direct Use of Geothermal Energy

As of 2009, direct utilization of geothermal energy worldwide is 50,583 MWt. The total annual energy use is 438,071 TJ (121,696 GWh). The five countries with the largest installed capacities are USA, China, Sweden, Norway and Germany accounting for 60 of the world's capacity, and the five countries with the largest annual energy use are China, USA, Sweden, Turkey, and Japan, accounting for 55 of the world use. However, an examination of the data in terms of land area or population shows that the smaller countries dominate, especially the Nordic ones. The largest increase in geothermal installed capacity (MWt) over the past 5 years are United Kingdom, Korea, Ireland, Spain and Netherlands and the largest increase in annual energy use (TJ year) over the past 5 years are United Kingdom, Netherlands, Korea, Norway and Ireland. All of these increases are due to geother-mal heat pump installations 12 . During the last decade, a number of countries have encouraged individual house owner to...

Industrial Waste

Little is published on the cost of the disposal of industrial wastes. The cost of toxic and hazardous waste disposal is known to be high and increasing. In addition, the personal liability of owners and managers of firms is increasing. Each proposed new environmental law imposes even more stringent requirements. As a result, capital expenditures and operating costs for industry have increased dramatically. One estimate is that every inch of paper added to regulations has increased industrial expenditures for environmental control by 10 million per year 7 , In general, industry does not assess the costs of environmental control but rather installs whatever end-of-the-pipe control is specified as the best available control technology by regulation. This limits their liability and negative press. A few companies search for more economic waste reduction technologies or new waste utilization systems. For example, when faced with the need to reduce emissions of volatile organic carbons...

Geothermal Energy

There are three components to the geothermal resource base (1) geothermal heating and cooling, or direct heating and cooling by surface or near-surface geothermal energy (2) hydrothermal systems involving the production of electricity using hot water or steam accessible within approximately 3 km of Earth's surface and (3) enhanced geothermal systems (EGS) using hydraulic stimulation to mine the heat stored in low-permeability rocks at depths down to 10 km and use it to generate electricity. Currently, geothermal heating provides approximately 28 GW of energy (mainly for heating and industrial applications). For example, municipalities and smaller communities provide district heating by circulating the hot water from aquifers through a distribution pipeline to the points of use. The barriers to increased penetration of direct geothermal heating and cooling systems are not technical, but with the high initial investment costs and the challenges associated with developing appropriate...

Benefits and costs

Large carbon reductions require a high overall efficiency with full use of the heat output, so there needs to be sufficient local heat demand. The construction of a heat supply system for district heating is most attractive for new residential areas, since it is far more costly to retrofit a heat supply network. However, in new residential housing where the requirement for heating has been reduced to a minimum through high energy efficiency standards, demand could prove insufficient to justify investment in a district heating system. Instead, heat demand can be covered by renewable energy sources such as solar thermal or ground source heat pumps.

Wind Power

Geothermal energy can be used to offset fossil fuels in several ways. First, the energy can be used to heat and cool buildings. Typically, a residential geothermal system relies on the fact that the Earth's temperate remains constant at about 55 degrees F (12.7 degrees C) at about 12 ft. (3.6 m.) below the surface. During the summer, the heat from the house is drawn down into the ground through a closed system, where it dissipates into the cool ground. During the winter, the relatively warm
