Abstract

A heat-recoverable tubular surface condenser, pertaining to the technical field of air conditioning and refrigeration. The utility model comprises a shell and a plurality of heat radiating copper pipes in the cavity of the shell. The condenser is characterized in: a partition is mounted horizontally in the shell to isolate the cavity in the shell into an upper part and a lower part, and the heat radiating copper pipes in the two parts are serially connected into a refrigerant loop, and the water channels are separated. Compared to the prior art, the utility model is provided with a built-in heat recovery unit, which simplifies the pipeline design, reduces the physical dimensions of the equipment, and reduces equipment cost.

Description

But the trumpet cooler of recuperation of heat

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.

In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:

But the trumpet cooler of recuperation of heat, it comprises housing and places many heat radiation copper pipes of number of housing inner chamber.Its design feature is, the horizontal positioned dividing plate is divided into upper and lower two parts with the housing inner chamber in the described housing, and two parts heat radiation copper pipe is connected into refrigerant loop and makes each water route separately.

In above-mentioned trumpet cooler, the area of described top heat radiation copper pipe accounts for 20%～30% of lower part heat radiation copper pipe area.

The utility model provides a spot of domestic hot-water owing to adopted said structure when making compressor air-discharging enter the condenser condenses heat exchange, refrigerant vapour condensation deutomerite flows to into evaporimeter.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.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Description of drawings

Fig. 1 is the utility model structural representation;

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

The specific embodiment

Referring to Fig. 1 and Fig. 2, the utility model comprises housing 3 and places many heat radiation copper pipes 2 of number of housing 3 inner chambers.Horizontal positioned dividing plate 1 is divided into upper and lower two parts with housing 3 inner chambers in the housing 3, and two parts heat radiation copper pipe 2 is connected into refrigerant loop and makes each water route separately.

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 20%～30% of bottom condensing heat-exchange effect heat radiation copper pipe 2 areas, and the sensible heat heat of recuperation of heat accounts for about 10% of condensation heat, and recuperation of heat amount ratio is 15%.Through calculating, 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

But the trumpet cooler of 1 recuperation of heat, it comprises housing (3) and places the many heat radiation copper pipes of number (2) of housing (3) inner chamber, it is characterized in that, the interior horizontal positioned dividing plate of described housing (3) (1) is divided into upper and lower two parts with housing (3) inner chamber, and two parts heat radiation copper pipes (2) are connected into refrigerant loop and make each water route separately.
2, but the trumpet cooler of recuperation of heat according to claim 1 is characterized in that, the area of described top heat radiation copper pipe (2) accounts for 20%～30% of lower part heat radiation copper pipe (2) area.
