For the concrete and cement specimens conservation standards in the
road transport, railways, bridges, civil construction, irrigation,
hydropower, scientific research units have extensive uses and the
promotion of greater value. National Standard (GBJ81-85) provides
concrete specimens of curing temperature of 203C, relative humidity
of 90%. In 1999, the state recommended the new standard
(GB/T17671-1999)cement specimens with conservation model for the
conservation room temperature of 201C, relative humidity of not
less than 90%. Conservation pool water temperature of 20C1. I plant
design HWS-SW-constant temperature and humidity control instrument
with the following features1. refrigeration and heating equipment
room on the conservation of the external avoid moist air corrosion
of the equipment. extension of the useful life of equipment and
reduce the failure rate, increase the reliability of the equipment
can be. 2, humidifiersultrasonic humidifier with fine spray
uniformity, no noise, reliability, water-conserving electricity. 3,
a high degree of automation in different temperatures in different
seasons, no artificial regulation, machines automatically converted
to thermal cooling system. ensure a constant temperature of 201C,
humidity above 90% RH. 4, computer control; The machines contain
microcomputer microcomputer temperature controller and humidity
controller In addition to accurate control of temperature and
humidity to go, but also show the number of conservation indoor
temperature and humidity, avoid the use of wet and dry ball
humidity temperature look-up table for trouble. The whole apparatus
consists of a set of closed refrigeration compressors, ventilation,
air duct and return air components, put cooling or heating up
through the air duct and drafts sent through the conservation
indoor drafts back to the crew back, repeatedly makes conservation
standards achieved room temperature, ultrasonic humidifier, spare
tank components humidification system, computer control of its
principles, as follows1, temperature controlconservation during the
summer months, when the indoor temperature rose to 21C, Outdoor
machines, producing a fan of wind (air conditioning refrigeration
principle) when the temperature dropped to 20machines stopped
working, In winter, when conservation of the indoor temperature of
19C, outdoor machines, Fans warming hot air (heat pump
air-conditioning system of the thermal principle) when the
temperature rose to 20C, the machine stopped working. 2, humidity
controlindoor conservation requirements in more than 90% RH.
Therefore, the conservation indoor set up a Taiwan ultrasonic spray
humidifier, computer humidity controller effective control of the
humidity of over 90%.
