Is provided.

[0006] Steam flows through the route R1. Route R2
A high concentration solution flows through R5. Routes R3 and R4
Low concentration solution flows. A refrigerant flows through the routes R6, R7, and R8. Cooling water flows through the route R9. Route R10
, Cold water flows.

[0007] A fuel supply device (107) in a direct-fired absorption refrigerator using gas or oil as fuel, and a steam supply device 107 such as a boiler in a steam absorption refrigerator, supply steam to a route R1. Cold water is circulated through a path R10 on the evaporator side of the lower shell / low pressure shell 103 in which the evaporator / absorber is housed in an integrated shell.

In the absorption refrigerator 100 having the above-described structure, the temperature of the cold water in the path R10 is reduced by the cycle of vaporization and liquefaction in the lower shell / low-pressure shell 103 in which the evaporator / absorber is housed in the integrated shell.

When the production, sales, and maintenance operations of the absorption chiller 100 having the above-described configuration are performed, various persons are involved in the operations.

[0010] The personnel involved in production include, for example, researchers, developers, designers, manufacturers, and purchasers. The personnel involved in sales consist of customers, manufacturers 'sales representatives, and distributors' sales representatives. Personnel involved in maintenance are maintenance and service personnel on the maker side and maintenance and service personnel on the agency side.

When a customer purchases an existing absorption chiller (off-the-shelf product), the customer obtains the product specifications from a product catalog or a sales person, and examines the purchase. When a customer purchases an absorption refrigerator including a standard product and a custom-made product having a desired specification, the customer and a sales representative execute a meeting regarding the specification.

Researchers, for example, carry out research on new technologies and elements to be mounted on new products. The developer executes, for example, the development of a new product to be introduced to the market and the development of a component device that performs a minor change of an existing product. The designer executes design of a product including a standard product and a custom-made product satisfying specifications required by a customer, for example. The manufacturer performs assembly of the designed product, for example. The purchaser performs, for example, the procurement of materials necessary for manufacturing the product.

[0013] The maker-side sales representative and the agency-side sales representative execute, for example, negotiations and negotiations between the maker and the customer, and between the maker and the agent.

The maker-side maintenance and service staff and the agency-side maintenance and service staff perform, for example, maintenance and repair of products that are operating at the customer's place.

[0015]

[Problems to be Solved by the Invention] The personnel involved in production (production staff), the personnel involved in sales (sales staff), and the personnel involved in maintenance (maintenance staff) are efficiently involved. Inexpensive and high-quality products can be quickly put on the market, and the absorption refrigerator can be operated in a good condition.

[0016] The sales person in charge of the catalog
Business negotiations are performed with reference to printed materials such as pamphlets and information registered in the portable computer. At the time of negotiations, the sales representative responds to the production representative for questions that cannot be handled by the customer due to lack of information.
Further, the salesperson executes the order receiving process at the sales office. The salesperson registers ordering information and specification information using an external terminal or a facsimile connected to the manufacturer's system.

From the negotiation staff, a system that can execute order processing at a customer after reducing the number of topics that cannot be answered immediately and always accessing and understanding the latest data in the company in order to reduce negotiation time and delivery time is desired. It is rare.

On the other hand, the production staff responds to inquiries while the sales staff is in negotiations. The production staff refers to the registered order information and specification information to execute product production in the most efficient manner.

[0019] From the production staff, there is a demand for a system capable of reducing the number of inquiries accompanying negotiations and promptly obtaining order information and specification information in order to improve the efficiency of daily work.

Also, the production staff, the research staff, the development staff, the design staff, and the manufacturing staff, and the purchasing staff are responsible for information related to the production work, such as work programs, work data, and work. Manage progress schedules individually. If the latest information is always shared as data that can be immediately viewed from any person in charge, it is possible to execute a quick and appropriate production operation.

The maintenance and service staff visits the installation location of the running product on a regular basis, inspects the status of the product, and checks the parts and components.
Replace consumables. In addition, the maintenance / service person goes to the installation location of the product in response to a repair request from the customer and executes the product repair / service.

A customer desires a maintenance service in which maintenance is performed in advance before the equipment that needs repair is in an unhealthy state or is shut down.

A system in which a person in charge of maintenance can preliminarily grasp a place where the equipment is likely to fall into an unhealthy state, and recommend maintenance to the customer while showing data and the like supporting such a place. Is desired.

Conventionally, information sharing among customers, production staff, sales staff and maintenance staff has been insufficient, and it has been difficult to respond quickly.

The present invention provides a product design management system capable of realizing information sharing and quickly responding to various situations.
