What is Pump?

What is a Pump?

The so-called pump is a device to concentrate the decentralized material and improve their bit energy. Heat is not material, but can, Hot concentration and increase the bit energy must be achieved through the carrier, the carrier is refrigerant. Heat pump is using of a small amount of high-grade electrical energy as a driving source of energy from the low-temperature scattered heat source to absorb low-grade heat and transfer to high-temperature heat source to achieve the pump heat purpose.

What is a Heat Pump?

Steam compression heat pump is currently the most common application of heat pump. This heat pump system works as below: the refrigerant is evaporated in the evaporator after absorbing heat, after evaporate into super-heated steam into the compressor, the refrigerant will be compressed into high temperature and pressure of the gas in the adiabatic compression of compressor. Then the condenser constant pressure condensed into low temperature and high pressure liquid, the liquid refrigerant flow past the throttle to become low-temperature low-pressure liquid, and then enter the evaporator to constant pressure endothermic, and then cycle back and forth. Heat pump water heater is transfer the heat in the air to water we need.

Heat pump technology is a technology to improve the energy grade, it is not the energy conversion process, so the energy conversion efficiency is not limited to 100% limit, but to comply with the inverse Carnot principle. The heat transfer coefficient of the heat transfer coefficient is also known as the Coefficient Of Performance (expressed in COP).Air source heat pump hot water equipment, the core technology is the energy efficiency ratio of COP value, selected air source heat pump hot water equipment, an important indicator should also be the size of COP value,when the energy efficiency ratio COP value is greater, means more energy-efficient.

And the effect of 0.25-mm coating, is equivalent to 10-cm to 15-cm glass wool, which can reflect 99.5% of infrared, 92.5% of visible light, and the highest sound insulation effect up to 68%,and the uniform sound insulation effect of more than 50%. Fireproof grade is A, and it is non-ignitable completely. This coating is Non-toxic and safety, with long-term durability, which service life is more than 15 years. If using this method, the construction is convenient and there is no harm for the original roof, and can prevent the roof of the aging. The plate surface temperature after construction is of 20 ℃ while comparing with before, largest indoor temperature can reach 8-10 ℃, the steel structure factory building energy consumption can be reduced to 30-70%.

Drafty Cooling:

Because some machines of the plant to generate heat and water vapor, the heat and water vapor if not discharge in time, will be accumulated in the plant, so that the steel structure workshop temperature will rise and affect the steel structure workshop environment. Solutions to these problems is to ensure that the plant drafty, install a moderate amount of suitable drafty system.  Proper exhaust system for steel structure workshop will significantly improve the air condition, lower the temperature in the steel structure factory building.

Install roofing unpowered drafty:

Unpowered ventilator is a kind of drafty equipment that dependents on air convection principle to ventilate, when diverge from indoor and outdoor air environment, will generate air activities, so as to eliminate indoor exhaust gas and heat. It doesn’t need the extra power, and it is environmental. But the dependence on the environment is strong, can't exhaust by force. Main products include turbine drafty, drafty bar (ribbon skylight drafty), the roof leak detector, etc.

Install roofing power exhaust fan:

Dining Room Furniture Ideas

Tables
Whether you're looking for round or oblong, rectangular or square, you'll find a table that suits your style. Some suggestions:

1. Round tables are best for smaller gatherings (and are ideal for family-style meals).

2. Round tables allow for less leeway when it comes to expanding your group (it’s tough to squeeze in extra guests).

3. Tables with leaves shrink and grow to suit smaller and larger groups.
4. When choosing your table size, don't forget to account for holiday entertaining. You don’t want to pack your guests in, but it’s reasonable to assume people will sit a bit closer than normal. We call it a “holiday factor:” a tight 2-inch gap between each chair.

Chairs
Striking that balance between comfort and modish is easier than you think:

1. Don't be afraid to mix and match. Try different chairs in the same color, the same chair in different colors, or the same materials with different patterns. Combine vintage and modern for diversity, or choose a variety of textures (woven, slipcovered, upholstered).

2. Chair heights are evocative. Higher backed armchairs project visual dominance; lower backed, armless chairs blend with your table.

3. Benches are ideal for more casual dining rooms. Mix with chairs or buy one for each side.

4. Chair cushions can add many things, from comfort to a pop of color. Bonus: Though they read mostly casual, you can remove them for formal affairs.

With these tips in hand we hope you're inspired to create the dining room of your dreams. Because fantastic meals deserve a backdrop to match. CDG furniture is a metal furniture manufacturers .

The 5 Benefits of Metal Furniture

Metal furniture has recently become an interesting topic in facility planning and design.

Once considered too utilitarian in style, contract metal furniture has developed a fresh surge in popularity for a variety of reasons including durability and cleanability. While wood furniture will always remain a popular option, here are the top five reasons to consider metal furniture for your group living, healthcare or camp environments:

1.Believe it or not, it has great style!  Metal furniture manufacturers have worked hard to create furniture that combines both form and function. Natural colors that are reminiscent of wood and laminate drawer faces can transform a basic piece of metal furniture into something indistinguishable from wood furniture aesthetically.

2.Cleanability and pest management. There is overwhelming scientific evidence that metal furniture does not deter bed bugs any better than wood furniture, but metal furniture does allow easier clean up and tolerates pest fighting chemicals better than wood due to its less absorbent surface. Metal furniture has bends, folds and board areas that still offer pests like bed bugs a place to hide so it is by no means bed bug or pest proof but with proper inspection and maintenance metal furniture can be a useful component of a pest management plan.

3.It’s got spirit & style! While most metal furniture is designed to mimic or blend in with wood furniture, metal can also be a great statement as part of a team or school spirit color design.  Standard primary color options or custom match paints are easy to achieve on metal furniture since metal does not the variations and graining of wood. Painted metal surfaces are consistent easy to standardize in for any color scheme.

4.Extreme durability. Metal furniture is a work horse of the contract furniture market. Metal furniture can tolerate extreme use which makes it perfect for any group living environment – especially dormitory and transient housing applications. Metal beds and bunk beds are durable and cleanable. Metal case pieces can include underbed storage, night stands, and chests of drawers. Metal’s finishes are well-sealed so with proper care metal beds and case pieces can withstand punctures, drink rings and general heavy use. What’s more, if the finish ever gets damaged do-it-yourself patch kits can create a like-new look in very little time.

5.It’s affordable. While good-quality metal furniture might have a higher sticker price than wood equivalents, you can expect metal furniture to last 10 – 15 years or longer.  Many metal furniture collections have warranties that will cover normal use for ten years or more. Metal furniture may require a larger up-front investment but the replacement cycle is less frequent.

Metal furniture is more and more used in restaurants, cafes, hotels and other public places, for the dining and leisure environment to create a highly durable, comfortable living space.
