Abstract

The utility model relates to the technical field of air conditioning refrigeration, in particular to a pipe type condenser in a thermal recovery type machine set. The thermal recovery pipe type condenser comprises a shell and a plurality of heat radiating pipes which are arranged in an inner cavity of the shell, a baffle plate is horizontally arranged in the shell for dividing the inner cavity of the shell into an upper part and a lower part, the heat radiating pipes of the two parts are connected in series into a coolant loop and separate each water path, and fins are arranged on the heat radiating pipes of the upper water path. The thermal recovery pipe type condenser adopts an integral series connection heat recovery condenser structure, simplifies the system pipeline design, and lowers the device cost under the condition that the appearance size of the machine set is not increased.

Description

Recuperation of heat tubular type condenser

Technical field

The utility model relates to the air conditioner refrigerating technical field, particularly the trumpet cooler in the heat reclamation type unit.

Background technology

The heat reclamation type handpiece Water Chilling Units can make full use of the heat of unit, provides the domestic hot-water in refrigeration, saves the unit power consumption, has certain environment protection significance, is just accepted by increasing user.But because how this product provide and guarantee that unit operation is stable and how not increase the appearance and size aspect with respect to common handpiece Water Chilling Units in the heat recovery water and have technological difficulties, cause this series products not at home market obtain extensive use.At present, the arrangement of condenser has two kinds in the heat reclamation type unit: the one, adopt parallel condenser, and the 2nd, adopt the tandem condenser.For the recuperation of heat handpiece Water Chilling Units, adopt the advantage of parallel condenser to be that recuperation of heat amount in theory can reach 100% of condensation load, the recuperation of heat amount can design control as required.Shortcoming is, the cold medium flux between two parallel condensing devices need be regulated by the variation of recuperation of heat amount, for making the unit can relatively stable operation, and realizes the required control relative complex of service requirement of being correlated with when operation.In fact really be used for the also few of recuperation of heat by this way.When adopting the tandem condenser, preposition condenser is a heat-recovery condenser, is used to absorb the superheat section of compressor assembly high-temperature exhaust air, so that the hot water of higher temperature to be provided; And rearmounted condenser is used for absorption refrigeration agent condensation heat release.The advantage of tandem condenser is that control is simple, but the condenser of series connection has increased the appearance and size of unit equally, makes the pipeline of system connect complexity, has increased the unit cost.

Summary of the invention

In order to overcome the shortcoming that exists in the above-mentioned prior art, but the purpose of this utility model provides a kind of trumpet cooler of recuperation of heat.Its built-in heat reclamation device has been simplified the circuit design of system, has reduced unit appearance and size, has reduced equipment cost.

The realization the technical solution of the utility model is as follows:

Recuperation of heat tubular type condenser, it comprises housing and places some radiating tubes of housing inner chamber, horizontal positioned one dividing plate in described housing, the housing inner chamber is divided into upper and lower two parts, two parts radiating tube is connected into refrigerant loop and makes each water route separately, on the radiating tube in last water route fin is set.

Described fin is wrapped on the radiating tube with one-piece auger.

The utility model is owing to adopted said structure, recuperation of heat tubular type condenser, it comprises housing and places some radiating tubes of housing inner chamber, horizontal positioned one dividing plate in described housing, the housing inner chamber is divided into, following two parts, two parts radiating tube is connected into refrigerant loop and makes each water route separately, on the radiating tube in last water route, be provided with fin with the one-piece auger winding, radiating tube in the last water route distributes the waste heat of taking out of from condenser, fin helps the better distribute heat of radiating tube that domestic water is provided, radiating tube in the following water route continues to distribute remaining waste heat, the utility model adopts the design of monoblock type series connection heat-recovery condenser designs simplification system pipeline, reduces equipment cost on the basis that does not increase unit appearance and size.

Fig. 2 is that the A-A of Fig. 1 is to schematic diagram;

Fig. 3 is the structural representation of the diffusing pipe of heat in the water route, top;

Among the figure, 1, housing, 2, radiating tube, 3, dividing plate, 4, fin.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises housing 1 and places many heat radiation copper pipes 2 of number of housing 1 inner chamber.Horizontal positioned dividing plate 3 is divided into upper and lower two parts with housing 1 inner chamber in the housing 1, and two parts heat radiation copper pipe 2 is connected into refrigerant loop and makes each water route separately, and one-piece auger twines and is provided with fin 4 on the radiating tube 2 in last water route.

When the utility model used, top heat radiation copper pipe 2 was a heat reclamation device, absorbs the superheat from the cold-producing medium that compressor discharge is come, and the hot water of higher temperature is provided.Cold-producing medium flows to lower part heat radiation copper pipe 2 again and carries out condensing heat-exchange.Heat radiation copper pipe 2 areas that play the recuperation of heat effect account for the 22%-28% of bottom condensing heat-exchange effect heat radiation copper pipe 2 areas, the radiating tube 2 that fin 4 helps to go up in the water route better dispels the heat, and the heat of recuperation of heat accounts for about 15% of condensation heat, and recuperation of heat amount ratio is 20%.Unnecessary recuperation of heat area only can increase degree of supercooling, can not cause the variation of condensation temperature, adopts the utility model both to reclaim superheat, and the domestic hot-water is provided, and has also increased the refrigerating capacity of unit simultaneously to a certain extent.

Claims
