Benefits of technology

[0007] In view of the aforesaid disadvantages, the present invention aims to provide a thin refrigeration air conditioner with a greater temperature difference to create a comfortable environment and also save energy. It includes a casing to house a thin heat exchanger, an air intake chamber, an air exit chamber, a side chamber and an air port baffle. The thin heat exchanger in associated with the air port baffle can control airflow amount to maintain a high temperature difference and low flow rate operation while the air and refrigerant flow through the thin heat exchanger to perform heat exchange process. Return airflow and airflow delivery can be maintained in a condition of an optimal temperature difference according to energy requirement of the A / C zone. Thus it can provide most comfortable condition and also save energy. It also takes less installation space and improves airflow distribution.

Problems solved by technology

Such a construction has problems in use, notably: 1.
Heat exchange efficiency is not desirable.
This results in waste of energy.
Moreover, when the conventional refrigeration air conditioner is used for refrigeration or freezers, due to its excessive height, the storage space is reduced.

first embodiment

[0018] Referring to FIGS. 2 and 3 for the invention. The thin refrigeration air conditioner 2 has an air fan motor 3 on one side (a front side or rear side). Air passes through the thin refrigeration air conditioner 2 to perform heat exchange, then is discharged through one or more air outlet B11 located on a ceiling B into an A / C room A to meet A / C requirement. The thin refrigeration air conditioner 2 includes a casing 20 which houses a thin heat exchanger 21, an air intake chamber 22, an air exit chamber 23, a side chamber 24 and an air port baffle 25.

[0019] The thin heat exchanger 21 contains a piping assembly 211 which has a refrigerant input end 2111 and a refrigerant output end 2112. The piping height H of the thin heat exchanger 21 is much smaller than the longitudinal length D of the piping, thus is a thin structure (referring to FIGS. 2 and 4). It further has a water collection tray 26 and a water discharge tube 27 on a rear end of the bottom thereof.

third embodiment

[0028] Refer to FIG. 6 for the invention. The refrigeration air conditioner 5 has an air fan motor 3 on one side. The refrigeration air conditioner 5 includes a casing 50 which houses a thin heat exchanger 51, an air intake chamber 52, an air exit chamber 53, a side chamber 54 and an air port baffle 55. The side chamber 54 further has a return air branch port 56 on the bottom. And the air intake chamber 52 and the side chamber 54 are divided by a spacer 57 without communicating with each other. The air port baffle 55 is located in the side chamber 54 and controlled by the controller 8 (referring to FIG. 9). The air port baffle 45 opens at a desired degree to control the amount of the second time air flowing through the return air branch port 56. After the second time air has entered the air exit chamber 53 and mixed up with the first time air, the temperature difference between the delivered A / C air and the return air from the return air branch port 56 is maintained at a minimum ran...

fourth embodiment

[0029] Refer to FIG. 7 for the invention. The refrigeration air conditioner 6 has an air fan motor 3 on one side. The refrigeration air conditioner 6 includes a casing 60 which houses a thin heat exchanger 61, an air intake chamber 62, an air exit chamber 63, a side chamber 64 and an air port baffle 65. The side chamber 64 further has a return air branch port 66 on the bottom. And the air intake chamber 62 and the side chamber 64 are divided by a spacer 67 without communicating with each other. The air port baffle 65 is located in the air exit chamber 63 and controlled by the controller 8 (referring to FIG. 9). The air port baffle 65 opens at a desired degree to control the amount of the first time air flowing out from the thin heat exchanger 61 and the second time air entering the side chamber 64.

Abstract

A thin refrigeration air conditioner has a casing which houses a thin heat exchanger, an air intake chamber, an air exit chamber, a side chamber and an air port baffle. The thin heat exchanger in cooperative with the air port baffle or a return air branch port can control airflow to maintain a high temperature difference and low flow rate operation while the air and refrigerant flow through the thin heat exchanger to perform heat exchange process. Return airflow and airflow delivery can be maintained in an optimal temperature difference condition according to energy requirement of the air conditioning zone. Thus it can provide a most comfortable condition and also save energy. It also takes less installation space and improves airflow distribution.

Description

BACKGROUND OF THE INPORTION [0001] 1. Field of the Invention [0002] The invention relates to a thin refrigeration air conditioner having a greater temperature difference and particularly to a thin refrigeration air conditioner that provides a comfortable and energy saving effect, does not occupy a lot of installation space, improves airflow distribution and delivers air at an optimal temperature difference. [0003] 2. Description of the Prior Art [0004] A conventional refrigeration air conditioner 1 (referring to FIG. 1) includes a heat exchanger 11 and an air fan motor 12 (to provide air conditioning (abbreviated A / C hereinafter) for an A / C room A0. Such a construction has problems in use, notably: [0005] 1. The longitudinal piping length D1 of the heat exchange 11 is relatively short. Hence the path length of air passing through the piping assembly 111 and heat exchange is short. Air temperature difference before and after the heat exchange is low. Heat exchange efficiency is not d...
