Abstract
A liquid refrigerant added in a liquid storage tank is introduced into a pipeline of an air conditioner in a machine room. Refrigeration of an expansion valve and an evaporator is released through a counterbalance valve, so that emergency refrigeration is realized.
Description
The data center of technical field high-grade (as the Tier4 standard of American TI A942) and the place that need uninterruptedly freeze
Technical background stops and oily machine when also not keeping supplying electricity when the machine room civil power, generally all come that air conditioner in machine room is carried out emergency service and realize emergent refrigeration by getting backup battery (UPS or EPS), the purchase of these equipment and operation maintenance at ordinary times all need very big expense.The present invention adopts another kind of refrigeration modes, reaches emergent refrigeration by the cold-producing medium that discharges in the additional fluid reservoir.
The summary of the invention air conditioner in machine room is when normal operation, and the gaseous state cryogen that general compressor is discharged is condensed into liquid refrigerant and is stored in the fluid reservoir in condenser, and after the expansion valve step-down, absorption refrigeration is to get back in the compressor behind the gaseous state in evaporimeter.The principle of emergent refrigeration of the present invention is that the source of the liquid refrigerant of emergent refrigeration is the cold-producing medium fluid reservoir that adds, through the expansion valve step-down, absorption refrigeration is that gaseous state discharges by counterbalance valve in evaporimeter, emergency service only need be to the power supply of the indoor fan of air conditioner in machine room and refrigeration does not need the participation of compressor and outdoor condenser like this, and buying and the operating cost of backup battery (UPS or EPS) are reduced greatly.
The specific embodiment:
As shown in the figure, refrigeration system is normally moved the refrigerant circulation loop of work, be to return compressor by 1 (compressor), 2 (condensers), 3 (reservoirs), 4 (expansion valves), 5 (evaporimeters), this moment, 8 (magnetic valves) were in opening, and 7 (magnetic valves) and 9 (magnetic valves) are in closed condition.
Closed circuit when refrigeration system is met an urgent need refrigeration, 8 (magnetic valves) cut out, 7 (magnetic valves) and 9 (magnetic valves) are opened, emergent cold-producing medium is set out by 6 (additional fluid reservoirs), through 7 (magnetic valves), 4 (expansion valves), 5 (evaporimeters), 9 (magnetic valves), reach refrigeration by the release of 10 (counterbalance valves).
How much what add the interior cold-producing medium of fluid reservoir is time and the refrigeration work consumption that depends on emergent refrigeration.
Description of drawings: 1, compressor 2, condenser 3, reservoir 4, expansion valve 5, evaporimeter 6, additional fluid reservoir 7, magnetic valve 8, magnetic valve 9, magnetic valve 10, counterbalance valve.
Claims (1)
1. during the refrigeration of meeting an urgent need, the liquid refrigerant in the additional fluid reservoir enters in the pipeline of Air Conditioning Facilities, reaches emergent refrigeration by discharging after expansion valve and the evaporimeter refrigeration.
