Plumbing

Piping is to install the tube (pipe) and the tube and the hose to protect the wiring etc. to transport the fluids such as the liquid, gases, and fine particles. The installed tube might be indicated and it say.

 

 

Liquid piping

 

The turbulent flow of jurisdiction causes wear-out and the corrosion of the

part.

 

* The water piping: Attention is necessary for damage in the cold district

by freezing.

o The drinking water: Such as breeding and the rust of the elution and bacilli of the

poisonous substance ..making impure.. is requested not to be.

o Water for miscellaneous use

o Drain: The characteristic put together at not deterioration by the element included

in drain but the temperature is necessary.

o The heat source water: It is necessary to keep it warm.

* Oil piping:

 

Gas piping

 

If pipes is not laid by an appropriate thickness, it becomes the loss of energy due to

the decrease in pressure and the temperature, etc.

 

* The steam pipework: The heat insulation put together at the temperature

is necessary.

* Compress air piping

* The fuel gas piping: The security devices such as gas leak alarm systems and the

emergency shut-off valves are necessary.

o City gas piping

o Lpg piping

* The refrigerative piping: The refrigerative piping is necessary between indoor units of the outdoor machine in Eacondishonar and the freezer etc. of the separation type.

* A special gas: A special gas is used in the hospital and the chemical factory, etc.Medical treatment gas piping, chemical plant piping, vacuum line, and aerospace piping, etc.

 

Fine particle piping

 

The jurisdiction part is made smooth because the fine particle is blocked, the bend is reduced,

and the consideration such as enlarging the curvature is especially necessary.

 

An explosiveness fine particle grounds the piping of straightening prevention about

static electricity, and uses the inert gas.

 

Moreover, the use of the screw conveyer flight conveyer bucket conveyer belt conveyer is preferable in the big one of the material and grain with a large adhered fine particle the density.

 

* Suck piping: The one transported by inhaling and making Gawa negative pressure. If the separation of the fine particle is insufficient, it causes the damage of the blower for the absorption.

* Force feed piping: The one transported by making sending side positive pressure. The

humidity management of the gas used is important.

 

Piping for wiring protection

 

Piping for instrumentation

Piping such as measurement equipment and control equipment, pressures,

temperatures, radiations, visible light rays, and measurement data transmissions,

etc.

 

Piping for electric installation

The electric wire tube and the electric wire duct are used to protect the cable for the commercial power of lighting equipment and the power equipment, etc. and the cable for the weak electric current equipment of the automatic fire information equipment and the broadcasting equipment, etc.To prevent the electric shock accident because of the leak beforehand, the tube is grounded without fail.

* F ..averting.. device

Heating

Heating is a generic name of the act the heat of the room and turning up the

heat.

 

The number also of heating where electricity was used is increasing in house heating before now though the central heating that uses the steam warmed with the technique or the boiler that burns kerosene, coal, the gas, and charcoal with the stove and takes was a main current.

(Japan〈Kanto?Kyushu〉It is likely to be used in the home where a sickly person and the senior citizen exist even if it is spring and autumn and a rainy season though) every three months of about the middle of November every year is necessary.

 

 

Classification according to heating method

 

* Netsden classification (heat transmission, radiation, and convection)

* Heat source classification (thermal storage (heated stone etc.) and flame, steam, heating air, and direct infrared rays that electric resistance, heat exchange, and single movement become possible, etc.)

* Consumption energy classification (natural energy such as fossil fuel,

electricity, and solar heats of kerosene and gas, etc.)

 

Classification that becomes standard when buying it

 

* Correspondence space ability (one that size of room was assumed to be

standard)

* Heating ability immediately (one that earliness at time achieved from room

temperature to preset temperature when starting was assumed to be standard)

* Initial cost (one including construction expense needed for purchase and

installation)

* Running cost (unit price, durability, and maintenance cost etc. of energy that is

necessary to obtain calorie)

* Convenience of fuel procurement (purchase of fuel and one by replenishment

labor)

 

Equipment for heating

 

* The one by fire

o Stove

o Fireplace

o Pechka

o Oil fan heater

o Gas heater with fan for combustion air and circulating

o Central heating

o Oil air conditioner

o Jet heater

o Brazier

o Hearth

o Kotatsu

o (Is it bean jam?)

 

 

* The one by compressor driving of gas engine drive

o Eacondishonar (Alias: Heat pump with Hepon and gas)

 

* The one by circulation of gas (one that the same space doesn't include

flame etc.)

o The one to warm air by solar heat and terrestrial heat and to

make it circulate(chiefly OM system)

o Korean stove

 

* The one with hot water

o Warm water type floor heating

o Warm water type panel heater

o Warm water type room heater

o Heating function with Hiyaonsi generator

o (hot-water bottle)

 

* The one by electricity

o Eacondishonar(alias: Air conditioner and heat pump by

electricity)

o Oil heater

o Ceramic heating resistor

o Electric stove

o Electric thermal storage heater

o Halogen heater

o Carbon heater

etc.)

o Electric foot warmer
