Product Description
The central air-conditioning system is composed of the cold heat source system and the atmosphere control system. The refrigeration system provides for the atmosphere control system must measure coldly, with counter-balances the indoor environment the cold load; The system hot system provides with counter-balances the indoor environment heat load for the atmosphere control system the quantity of heat. The refrigeration system is the central air-conditioning system very important part, it used the type, the movement way, the structural style and so on immediate influence central air-conditioning system's in movement efficiency, highly effective, the rationality.
Central air conditioning commonly used terminology
1st, comfortable air conditioning:
Causes the air conditioned room to satisfy the request which the people live, controls the room by human body's comfortable request the air parameter.
2nd, technological air conditioning; Also said that the constant temperature constant humidity air conditioning, causes indoor parameter controls and so on air temperature, humidity, stream velocity, cleanness based on this, satisfies the technique of production the request
2nd, technological air conditioning; Also said that the constant temperature constant humidity air conditioning, causes indoor parameter controls and so on air temperature, humidity, stream velocity, cleanness based on this, satisfies the technique of production the request
3rd, refrigeration quantity: When the air-conditioner carries on the refrigeration movement, in the unit interval/unit time, the low pressure side refrigerant the quantity of heat which absorbs in the evaporator. The commonly used unit is W or KW.
4th, heat pump system quantity of heat; The air-conditioner carries on when the heat pump system hot movement (heat pump auxiliary electric heater should simultaneously movement) in the unit interval/unit time send in airtight spatial, the room or the region quantity of heat.
5th, coefficient of performance: The refrigeration (heat) circulates the refrigeration which produces (heat) the quantity and the refrigeration (heat) consumes ratio of the electric power is the coefficient of performance. When refrigeration is called the energy efficiency ratio, indicated with EER: Makes when the heat is called the coefficient of performance, indicated with COP.
6th, air blower serpentined: In collection central air-conditioning system commonly used heat exchange equipment, and so on is composed of the finned tube and the air blower, the secondary refrigerant flows through the air blower serpentined (in tube) when with the tube place air heat transfer, causes the air temperature decrease. The air blower serpentined belongs to the air cooling equipment.
7th, water cooling cold water unit: The water cooling cold water unit belongs to the central air-conditioning system's refrigeration unit part, its secondary refrigerant is the water, is called cold water unit, but condenser's cooling often the lukewarm water heat transfer temperature decrease realizes for the use, thus is called for the water cooling unit. Relative is called the forced-air cooling unit with the water cooling machine, the forced-air cooling unit's condenser by serves the cooling purpose with the room air forced draft heat transfer.
8th, module machine: Develops in the VRV system's foundation comes, in 1985, invented by the Australian Czechoslovakia abundant group and applies special. It the traditional freon pipeline change is the waterway system, the indoor outside machine merge is the refrigeration unit, the indoor machine changes the air blower serpentined. Realizes the refrigeration process using the secondary refrigerant water's heat transfer, the module machine, because can act according to the cold burden requirement automatic control start unit quantity, realizes the nimble combination to acquire fame.
