3. Structure and principle
The equipment mainly consists of: control device and heating and cooling circulation equipment, air conditioner outdoor unit, ventilation duct, industrial humidifier (high-pressure spray pump) . This device applies a temperature and humidity synchronous control method, that is, blowing hot air in winter to raise the indoor humidity to the required temperature. Conversely, cold air blows out in summer to lower the indoor temperature to the desired temperature. The humidity will be automatically controlled according to the instrument setting value, achieving the purpose of fully automatic constant temperature and humidity.
4. Design and construction parameters of the standard curing room
The standard curing room for concrete specimens is in working condition all year round. There are three ways to save energy: the height of the standard curing room is about 100 meters, the volume should not be too large, the thermal insulation performance should be good, and there should be specimens rack to make full use of space. There should be no windows in the standard breeding room, and the door should be well sealed (and should also be insulated and decorated). The roof and four walls of the standard breeding room should be insulated. The standard maintenance room has certain requirements for electricity and water. When the machine is turned on normally, no power or water outage is allowed, otherwise parts will be burned. And seriously affect the quality of maintenance.
5. Equipment installation
(i) The installation sequence is: host machine, refrigeration unit
(ii) Unit
Selection of machine location: Selection of refrigeration unit.
There should be at least space around the unit as close as possible to the standard maintenance room to facilitate maintenance and installation.
The refrigeration unit should be installed outdoors to facilitate the isolation of heat dissipation and noise. Use copper pipes to connect and seal the host. The closer the distance between the host and the unit, the better, to achieve the best cooling effect. The installed solar In places where there is no direct radiation, dust and corrosive gases, the operating temperature of the unit should not be higher than ℃. The working voltage needs to be stable, and the condensation fins should be cleaned frequently with water to make the machine work properly and save electricity.
(iii) Circuit installation
The sensor cable should pass through the hole in the wall and enter the standard maintenance room. It should be stringed along the aluminum-plastic pipe. The hanging height of the sensor bracket is about the center position from the air outlet to the ground.
The ground wire of the unit must be firmly connected to a professional ground wire. For example, if a temporary house does not have a special ground wire, a ground wire welded with a steel plate should be buried.
The above various wires and cables are fixed on the wall with cement nails. Their direction should be horizontal and vertical, even and neat.
6. Use and maintenance
Before testing the machine, check the pipeline or circuit according to the instruction manual. There must be no errors and whether the voltage is (three-phase four-wire). You must understand the instruction manual before you can test the machine in the following steps.
Instructions for use
Turn on the power switch. The temperature and humidity setting values of this instrument have been set before leaving the factory, so there is no need to adjust it yourself.
When the ambient temperature is higher than the set value, the host air conditioner works and the air cooler blows out cold air to reduce the indoor temperature to the set value.
When the ambient temperature drops below the set value, the hot air blower blows out hot air to raise the indoor temperature to the set value. If it is difficult to raise the indoor temperature, this device is equipped with an auxiliary heating system.
When the humidity is lower than the set value, the host drives the high-pressure pump to start humidifying, and vice versa, it stops working.
Maintenance
The instrument must be maintained by dedicated personnel. During use, the operation status of each state must be checked frequently. Tap water and power must be supplied normally to avoid affecting the maintenance effect or damaging the unit. Sewage maintenance is required after one month of use. The indoor floor It should be cleaned frequently. If the refrigeration effect is poor, fluorine should be replenished. Please ask professional air conditioning and refrigeration maintenance workers to do it. Connect the liquid filling pipe on the low pressure side. When the temperature of the two copper pipes of the unit is close to the same, the fluorine is full.
. Check the working status of the cooler and whether the cooling system is blocked by dust. If the above phenomenon occurs, please flush the condenser with water. If there is less fluorine, the refrigerant R should be replenished in time.
After the machine has been in operation for one year, the cable aging procedure should be checked to prevent leakage, and the sensitivity of the leakage protection switch should be checked at the same time.
Add mechanical oil to the high-pressure pump regularly, and the water used must be absolutely clean.
