Nowadays, there are many hotels, baths, office buildings, schools, hospitals and factories. At the same time, there are air-conditioning centralized cooling and domestic hot water supply. Carrier launched 30HXC total heat recovery screw unit, through the discharge of water chillers into the atmosphere The condensed heat is recovered to make hot water, which makes the energy of central air conditioning effective. Using, the energy consumption of users is greatly reduced, the economic benefit is effectively improved, and at the same time, it can be reduced. Environmental pollution caused by condensation heat. 30HXC total heat recovery screw unit is energy-saving. New choice of environmental protection air conditioning system.
Working principle of Carrier 30HXC full heat recovery screw chiller Carrier 30HXC full heat recovery screw chiller adopts single-cylinder double-loop condenser. Structural design, by adding a heat recovery loop to recover all condensation heat. As shown in the figure The unit with heat recovery option is shown. There is hot water in and out on the condenser. Interface, convenient for users to install and use.
Flowchart of Carrier 30HXC Total Heat Recovery Screw Chiller System When cooling: turn on the cooling water pump and turn off the hot water pump. The unit is in refrigeration priority mode. Run. Heat recovery: turn on the hot water pump and turn off the cooling water pump. The unit can give priority to refrigeration. Mode operation, controlling the outlet water temperature of evaporator; It can also be transported according to the heat recovery priority mode. Ok, control the temperature of hot water.
In winter, there are suitable low-temperature heat sources (such as groundwater, surface water, soil source, medium) Water, etc.) can be used, the low-temperature heat source water can be connected to the evaporator of the unit, through the whole Preparation of high temperature hot water by heat recovery unit. In this case, the total heat recovery unit can be completed. Completely replace the boiler and make hot water all year round.
Option description
The water chamber interfaces of evaporator and condenser can be reversed respectively.
The standard unit water chamber interface is on the right side of the unit (with the control cabinet as the front), and this option provides the left water chamber interface.
Evaporator and condenser water chamber can provide
1.6MPa/2.1MPa high pressure option.
Cryogenic unit
Outlet temperature range of low-temperature ethylene glycol or salt solution evaporator: -6℃~+4℃
Some models can provide the lowest temperature option of -10℃ to meet the needs of process refrigeration application.
Silent cabinet
The first generation of quiet speakers can reduce the noise of the unit by more than 10dB(A) on average: the installation and disassembly are convenient, which has no influence on the maintenance and management of the unit and has a beautiful appearance (see P3 in this book).
