In the heat recovery control system, the outdoor condenser is respectively connected with the refrigerating unit and the shell-and-tube heat exchanger through a tee joint, and the refrigerating unit is respectively connected with the control valve I and the control valve II through a tee joint.
The utility model has the advantages that:
1. the utility model relates to a heat recovery control system, this structure are applicable to among the various refrigerating unit uses, specifically are the shell and tube heat exchanger that adopts the condenser of refrigerating unit to connect in parallel, and hot water after the heat transfer through shell and tube heat exchanger pours into the hot-water tank into, supplies air conditioning system to use.
The utility model discloses a structure produces a large amount of heats with the condenser and retrieves to collect it in the hot-water tank, provide the heat source, supply the user to use, this structure is very big has utilized this partial dumped heat, effectively improves refrigeration plant's utilization ratio, has made a tractor serves several purposes, and cold and hot coproduction reduces the waste of heat, produces considerable economic benefits.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
example 1:
a heat recovery control system, comprising: the refrigeration unit comprises a refrigeration unit 1, the refrigeration unit is respectively connected with an outdoor condenser 2 and a shell-and-tube heat exchanger 5 in parallel, the outdoor condenser is sequentially connected with the shell-and-tube heat exchanger through a control valve II3 and a control valve I4, the shell-and-tube heat exchanger is connected with one end of a hot water pump 8 through a control valve III6, the other end of the hot water pump is connected with a hot water tank 7 through a pipeline, and the hot water tank is connected with the shell-and-tube heat exchanger through a pipeline.
Example 2:
according to the heat recovery control system of embodiment 1, the outdoor condenser is respectively connected with the refrigerating unit and the shell-and-tube heat exchanger through a tee joint, and the refrigerating unit is respectively connected with the control valve I and the control valve II through a tee joint.
Example 3:
the heat recovery method of the heat recovery control system according to embodiment 1-2, the method comprising the steps of:
firstly, high-temperature gas of a refrigerating unit enters an outdoor condenser through a control valve II for condensation, when a heat recovery system is required to be put into the outdoor condenser, the high-temperature gas enters a shell-and-tube heat exchanger through the control valve I, and hot water after heat exchange is sent into a hot water tank through a hot water pump through a control valve III for a user to use;
the shell-and-tube heat exchanger and the outdoor condenser are used for condensing the refrigerating unit and heating the refrigerating unit at the same time, when the heat recovery runs, the opening of the control valve III determines the flow rate of hot water, the temperature of a hot water outlet of the shell-and-tube heat exchanger is kept constant through a PID (proportion integration differentiation) adjusting mode, and meanwhile, the hot water pump also uses the PID adjusting mode to keep the water supply pressure constant.
Claims (2)
